Life-Sized Models and Dinosaur Facts

The Dinosaurs Alive exhibition was a recent highlight of the fair at the PNE in Vancouver, British Columbia. The annual fair is held in the second half of August and takes place at the Pacific National Exhibition in Hastings Park. The dinosaur exhibition consisted of life-sized or close to life-sized models, many of which were animatronic. The models were a great introduction to the real animals.

This article contains photos of some of the models as well as facts about dinosaurs in general and information about the real-life versions of the species on display. The photos were taken by me during my visits to the fair.

Introduction to Dinosaurs

Dinosaurs appeared about 230 million years ago. They became extinct around 66 million years ago (according to the latest assessments), except for the evolutionary line that produced modern birds. Birds have many skeletal similarities to dinosaurs as well as scales on their feet and the lower part of the legs. The similarities are so striking that many biologists consider birds to be a type of dinosaur instead of simply being descended from dinosaurs. Based on this idea, dinosaurs didn't become extinct. They live on in the form of birds.

As a group, dinosaurs were highly successful and existed for a very long time. During this time period, some species disappeared and others appeared. Based on our discoveries so far, the smallest species were slightly bigger than a chicken. We've discovered only limited remains of big animals, so their size is hard to estimate. Some seemed to have been huge, however.

The biggest dinosaurs known at the moment belonged to a group known as sauropods. These herbivorous animals had a very long neck and tail. Argentinosaurus huinculensis is believed to have been a massive sauropod and may have been one of the longest dinosaurs. It had an estimated length of 35 to 37 metres (114.8 to 121.4 feet). A single vertebra of this animal is as tall as a human.

Scales and Feathers

Scientists are continuing to find dinosaur fossils and are discovering new features of the animals' bodies and lives. Many dinosaurs seem to have been covered by scales, but some had feathers. The list of feathered animals is growing.

Dinosaur forelimbs covered in feathers are sometimes referred to as "wings", but researchers say that it's unlikely that feathered dinosaurs could fly. The feathers are believed to have been used for insulation or in displays to other members of the species. It's thought that some of the smaller and lighter feathered dinosaurs might have been able to glide, however. The idea that some of them could also fly hasn't been completely ruled out, especially in the evolutionary line that eventually produced today's birds.


The fact that some dinosaurs had feathers has been established by the fossil record. Less certain is the idea that dinosaurs were warm-blooded (endothermic) instead of cold blooded (ectothermic). The term "warm-blooded" means that an animal maintains a warm temperature by processes and adaptations within their body. Cold-blooded animals have to change their body temperature by behaviours such as sun bathing to warm themselves up and moving into the shade to cool themselves down.

The proposal that at least some dinosaurs were endothermic is based on bone structure that seems to indicate rapid growth in the animals. Some researchers think that this high growth rate meant that dinosaurs must have been able to maintain a warm body temperature. Other researchers are less impressed by the evidence in the bones and think that the dinosaurs might have been mesothermic. A mesothermic animal can partially regulate its temperature by internal processes. The great white shark is an example of a modern animal that is mesothermic.

Biological Classification of Dinosaurs

Two different systems of biological classification are used—the Linnaean system, which is generally used by school students and the general public, and the phylogenetic system, which is used by most biologists. In the Linnaean system, organisms are placed in categories based on their appearance and structure. The phylogenetic system is based on clades (groups of organisms with a common ancestor) and evolutionary lines.

All dinosaurs belong to the clade known as the Dinosauria. This contains two smaller clades—the Ornithischia or bird-hipped dinosaurs and the Saurischia or lizard-hipped dinosaurs. Each of these contains even smaller clades. One of the clades within the Saurischia—the Therapoda—gave rise to modern birds.

It might be thought that birds must have originated from the Ornithischia, since the scientific and common name of the clade refers to birds. Biologists say that this isn't the case, however. A hip that resembles the one found in birds evolved twice in the dinosaur lineage—once in the Ornithischian line and once in the Saurischian line that led to birds.

We don't know the colour of Dakotaraptor, but we do know that the feathers of Archaeopteryx were black and white.

The Dinosaurs Alive Exhibit: A Brief Review

The Dinosaurs Alive exhibit at the PNE included twenty dinosaurs, fourteen of which were animatronic. Moving parts in the animatronic models included some combination of the head, mouth, tongue, eyes, neck, tail, forelegs, or a hind leg. A roaring sound was played as a dinosaur moved, which was meant to represent the animal's voice.

The exhibit was both entertaining and educational, although it had some problems. One of these was the realism of the surface of some of the dinosaurs. The models had a slightly shiny, rubberized appearance. Bumps were used to represent scales. These features were successful in some models but less so in other ones. I did like the fact that the models had some accurate structural details and that their features reflected recent research, however.

Dinosaur facts were posted around the exhibit as well as in front of the models. More information would have been nice, though, especially in relation to the models and their real-life counterparts. The availability of a knowledgeable person who could answer people's questions would have been a great enhancement to the exhibit. A printed, audio, or downloadable tour guide would probably have been useful, too. The Dinosaurs Alive exhibit was free with admission to the PNE fair, however, which might have limited the desire of the exhibit's owner to offer anything other than a basic self-guided tour. Facts about some of the real dinosaurs depicted in the exhibit are given below.

Dakotaraptor was discovered in South Dakota and lived about 66 million years ago. It was a bipedal predator that was about 5.5 metres or 18 feet long. It's one of the biggest raptors known so far. "Raptor" is the common name for dinosaurs belonging to the Dromaeosauridae clade (or the Dromaeosauridae family in the Linnaean system). Velociraptor is another animal that belongs to the clade. This raptor was the size of a turkey, despite its depiction as a large animal in Hollywood movies.

The ulna from the forelimb of Dakotaraptor shows quill knobs where feathers were attached. Its forelimbs and perhaps its whole body were covered by feathers. A claw from the forearm can often be seen at the bottom of the wing in reconstructions of the animal. The term "wing" is used as a term for the feathered forelimb, as is often the case in dinosaur biology. Like Ostriches, Dakotaraptor couldn't fly. The large, curved claws on the animal's feet are known as sickle claws and were likely used to kill or hold down prey. The animal is thought to have been a good runner.

The model of Dakotaraptor in the Dinosaurs Alive exhibit looked more heavyset than the version shown in the illustration above. Neither the creator of the model nor the artist has made an error. Fossil remains of two versions of the dinosaur have been discovered. One version is slender while the other is robust. It's thought that this difference may be an example of sexual dimorphism. This is a phenomenon in which the male and the female of a species have noticeable differences in appearance. It's unknown whether the robust Dakotaraptor was the male or the female.

The Dakotaraptor model is more heavyset than the version shown on the identification sign. An explanation for this disparity would have been useful for the public.

Qianzhousaurus was a relative of Tyrannosaurus rex. It has been nicknamed Pinnochio rex due to its long snout. The dinosaur was discovered in China and like Dakotaraptor is thought to have lived about 66 million years ago. Its discovery was reported in 2014 and was exciting for the scientists who had suspected that long-snouted tyrannosaurs existed. Qianzhousaurus and T. rex belong to the clade (or family) known as the Tyrannosauridae.

Qianzhousaurus was a carnivore, like its relatives. It was probably a fearsome predator. It had long and narrow teeth while T. rex had wider ones. There were other differences between the snouts of the two animals, including the fact that Qianzhousaurus had small horns on the top of the snout.

Some dinosaurs had hair-like fibres on parts of their body, which formed what has been called "dino fuzz". The fibres were actually feather precursors or proto-feathers. Some researchers strongly suspect that T. rex and its relatives had this fuzz, at least in their juvenile stages. Others disagree with this idea. The creators of the Dinosaurs Alive exhibit have chosen to put the fibres on the back of the Qianzhousaurus model and on the juvenile T. rex model.

Tyrannosaurus rex

Tyrannosaurus rex lived in what is today western North America. At the time when T. rex was alive, the area was an island continent known as Laramidia. Laramidia was separated from the rest of North America by ocean. T. rex fossils date from 68 to 66 million years ago. The animal was a predator, though it may also have scavenged food.

Unlike the case for most dinosaurs, many T. rex fossils have been found. Even preserved soft tissue in the form of protein inside the animal’s bones (and recently in the bones of other dinosaurs) has been identified in fossils. This is a very exciting discovery, since soft tissue rarely survives the fossilization process. Dinosaur DNA hasn’t been found, however.

The largest and most complete T. rex skeleton known today has been named Sue. In life, Sue was about 12.3 metres (40 feet) long and about 3.7 metres (12 feet) tall at the hips. She died at about 28 years of age, which is thought to be around the maximum lifespan for her species.

T. rex had a very large head and a long tail. It was bipedal and walked on its powerful hind limbs. The forelimbs were much smaller. They each had two digits with claws and a smaller third digit without claws. The puzzle about whether the animal had feathers and if so to what extent is one that many scientists would love to solve. A covering of proto-feathers would change the appearance of T. rex significantly.




Regaliceratops was a horned dinosaur that was closely related to the better-known Triceratops. Both animals belonged to the clade or family known as the Ceratopsidae. Regaliceratops is believed to have lived about 70 million years ago. Its remains were discovered in the province of Alberta in Canada.

Unlike all the animals shown above, Regaliceratops belonged to the Ornithischian line of dinosaurs and was a quadruped. It was also a herbivorous animal. It had a large horn on its nose, a smaller horn over each eye, and other projections on its head. It also had a huge, decorated frill behind its head. The massive skull and frill of one animal was found to weigh 592 pounds once it was extracted from the ground.

The function or functions of the head ornamentation is unknown, but there are some theories in relation to Triceratops that may apply to Regaliceratops as well. The projections may have been used for defence. They may also have been used in courtship displays or in dominance displays when interacting with rivals.




Like Regaliceratops, Pinacosaurus was an Ornithischian dinosaur, a quadruped, and a herbivore. It lived in China and Mongolia 80 million to 75 million years ago. The animal is notable for the spikes on its head, the spiked plates of bone along its back that look like a suit of armour and the bony, club-shaped structure at the end of its tail.

Pinacosaurus belonged to the clade or family known as the Ankylosauridae. The clade contained armoured dinosaurs, which are sometimes referred to as living tanks. Their dermal plates protected them from their enemies. Their tail club is believed to have been used as a weapon.

Since bones of multiple Pinacosauruses have been found together, researchers suspect that the animals travelled in groups or herds. Their armour would probably have been excellent protection from predators, unless the herbivores were somehow flipped on to their back. This would have exposed their soft and vulnerable belly.

The Advantage of Dinosaur Models

Models can bring dinosaurs to life in a way that may not be possible for an illustration, especially when the models are life-sized. In order for this to happen, though, the model must be as realistic as possible. Ideally, it should also be based on our latest knowledge of dinosaurs. This may not be possible due to the expense of creating a large model and the time required for its creation.

The Dinosaurs Alive exhibition has appeared twice at the PNE fair. The 2016 exhibition was larger and more interesting than the 2015 one and was the basis for this article. It was definitely worth visiting, despite its limitations.

In 2017, an animatronic display of giant insects replaced the dinosaurs, which I didn't find as interesting. The dinosaurs weren’t present at the 2018 fair, either. In 2019, a display called Dinosaur Stomp appeared at the fair. The animated models in this display were created by the same company that created the Dinosaurs Alive exhibition.

I hope that another dinosaur exhibit appears at the PNE soon, perhaps in an improved form. Dinosaurs are a fascinating and intriguing group of animals. It's very enjoyable to learn about them.

Hi Linda. Your pictures are great. This is an interesting hub and the fair looks like it would be a lot of fun. Thanks for sharing your information and pictures.

Blessings to you.

Linda Crampton (author) from British Columbia, Canada on September 20, 2016:

Thank you for the interesting comment, Alun. I think that biological classification is both useful and frustrating at the same time. I share your view that there are problems with the Linnaean system. I think that's to be expected when we try to impose a human system of categorizing things on the natural world. The cladistic system seems to work better because it's based on evolutionary relationships. Scientists don't agree on all of these relationships, though, which can make the results confusing. They are often intriguing results, though!

Greensleeves Hubs from Essex, UK on September 20, 2016:

Nothing in the world of animal life interests me so much as prehistoric life Linda, and none of course are so dramatic and other-worldly as dinosaurs. It's good to see any exhibition of dinosaur models and I guess this one, with its animatronics, will appeal to children. And it's very good that some of the lesser known species are included too (some that I've never heard of), because that serves to illustrate the vast range of species within this enormously successful group of animals.

I must admit I'm still more familiar with the old Linnaean classification, than the modern cladistic system, but using that older system I've always had issues. Traditionally dinosaurs have been classified as reptiles. And yet I've always felt for reasons too involved to go into here, that differences in anatomy and physiology were so great that dinosaurs should really be considered quite separately from reptiles, in a class of vertebrates all of their own. Equally however, I feel that birds - although evolved from dinosaurs - are sufficiently distinct today to retain their own class status - Aves. Anyway, that's just a personal view.

Thanks for your article and your photos. Alun

You have interesting and detailed information and this topic.

Linda Crampton (author) from British Columbia, Canada on September 19, 2016:

Hi, Audrey. I agree - the exhibit is both fascinating and fun!

AudreyHowitt on September 19, 2016:

What fun! Fascinating and fun!

Linda Crampton (author) from British Columbia, Canada on September 19, 2016:

Thank you for the visit and the comment, ValKaras. Dinosaur history is definitely amazing! I think it's fascinating as well.

ValKaras on September 19, 2016:

A very interesting hub, indeed. If one doesn't know something about it as you do, who would ever think that birds have anything to do with those prehistoric monsters - except sit on their backs. It's amazing stuff, Linda, thank you for sharing.

Linda Crampton (author) from British Columbia, Canada on September 18, 2016:

Thank you for the very interesting comment, Deb. Evolution and adaptation in animals are fascinating topics to explore.

Deb Hirt on September 18, 2016:

So much is being considered now. The claw near the elbow in ancient birds could be the rear facing claw on some perching birds. To make a long story short, after every ice age and readjustment in climate, "new animals" have come into being to survive the next challenge with new climate. We are already seeing new species, two from the wood warblers, in fact, that should be good survival candidates for the upcoming climate challenge. Some animals will perish, of course, but there are so many others that will continue to be our future. By the way, I would query the fact that your dakotaraptor is kin to the Greater Roadrunner. It would be quite interesting to work on THAT project!

Linda Crampton (author) from British Columbia, Canada on September 14, 2016:

Thank you, Martie. I appreciate your comment. It's very interesting to think about dinosaurs having feathers!

Martie on September 14, 2016:

Hi Alicia, this is an extremely interesting article about dinosaurs. Can't imagine those huge ones with feathers. Excellent article!

Linda Crampton (author) from British Columbia, Canada on September 12, 2016:

I find studying the past fascinating, too, Larry. As you say, there are so many puzzles to solve! Thanks for the visit.

Larry Rankin from Oklahoma on September 12, 2016:

So many puzzle pieces to put together. I'm always fascinated with archaeology.

Linda Crampton (author) from British Columbia, Canada on September 09, 2016:

Thank you very much, Vellur. The dinosaurs are certainly interesting. I hope to see the exhibit again in the not too distant future.

Nithya Venkat from Dubai on September 09, 2016:

Dinosaur Fair is amazing! So many types of dinosaurs, great photos. Learned a lot about dinosaurs reading your interesting and informative hub.

Linda Crampton (author) from British Columbia, Canada on September 05, 2016:

Hi, vespawoolf. Yes, the exhibit is educational and very interesting. It's worth seeing, especially for people who are fascinated by dinosaurs. Thanks for commenting.

Vespa Woolf from Peru, South America on September 05, 2016:

What an educational and fascinating exhibit! I've been interested in dinosaurs since I was young, and the Jurassic Park movies certainly heightened interest in these prehistoric creatures. How interesting that they're most closely related to birds. Thank you for sharing your personal photos, too.

Linda Crampton (author) from British Columbia, Canada on September 04, 2016:

Thank you very much, Devika.

DDE on September 04, 2016:

An informative hub and with lovely photos.

Linda Crampton (author) from British Columbia, Canada on September 03, 2016:

Hi, Suhail. Thanks for the visit. The movie industry has a lot to answer for with respect to people's understanding of dinosaurs! I hope Dinosaurs Alive visits your part of Canada soon.

Suhail and my dog on September 03, 2016:

Hi Linda,

I love to read about dinosaurs and this hub was no exception.

What you wrote about Dakotaraptor and the size of velociraptors is something everybody should know. I don't know why they chose to use velociraptors in Jurassic Park series of movies. They would have been better of using Deinonychus instead.

And finally, I wish I could attend the Dinosaurs Alive at PNE.

Linda Crampton (author) from British Columbia, Canada on September 01, 2016:

Hi, Faith. I think you would have enjoyed the Dinosaur Alive display if it was as good as the Vancouver one. Some of the dinosaurs would have been terrifying in real life, but they would have been interesting, too! Thank you very much for the comment.

Faith Reaper from southern USA on September 01, 2016:

Interesting hub, Alicia. Thank you for taking us along with you to the great exhibit. There was a Dinosaur Alive exhibit in the city in which I work one weekend not too long ago, and I so wanted to take my grandchildren, but that particular weekend they already had other plans. I know they would have love it. And after reading this, I wish I had gone anyway without the grands.

I couldn't even imagine living among the dinosaurs, especially the T-rex, would have been terrifying to me. It is hard to picture them with feathers!

I appreciate all the details and photos you've included. Wonderful hub!

Linda Crampton (author) from British Columbia, Canada on August 31, 2016:

Thank you very much, Manatita. I appreciate your kind comment, as I always do. I'm guessing that you're referring to the Natural History Museum in your comment. I went there many years ago and found it fascinating. I'd love to go there again! Best wishes to you, Manatita.

manatita44 on August 31, 2016:

Thanks Alicia. A very well-written article, and with much work put in. You've made the dinosaurs very life-like and the models are probably great for kids. I've seen them in theme parks and movies which were quite scary.

Interesting take on birds. Most certainly much gentler. We do have a great museum in London, near South Kensington, where quite a few are on display. Many tourists and nationals with groups of children go there.

Once again, great to see your wonderful write on dinosaurs. Much Love.

Linda Crampton (author) from British Columbia, Canada on August 31, 2016:

Hi, Mel. Thanks for such an interesting comment. Top down seems to make more sense to me, too. I'll have to research both ideas to see what the evidence or reasoning is. It can be difficult learning about dinosaurs from indirect evidence, but it's so interesting!

Mel Carriere from San Diego California on August 31, 2016:

Having feathers doesn't make them any more cute and cuddly. These "terrible lizards" are not lizards at all, but birds! There are two theories, called "top down" and "bottom up" to explain how dinosaurs began to fly. Top down says they started in trees and began to glide down, bottom up that they were on the ground and leapt into the sky. We're talking over millions of years, of course. Top down seems to make more sense but I think bottom up has more adherents. Any thoughts?

This was great. I learned a lot.

Linda Crampton (author) from British Columbia, Canada on August 30, 2016:

Hi, Jodah. Thank you for the comment. I've been interested in dinosaurs for a long time, too. I think it's exciting that information about them is still being discovered. Hopefully new models will be created as new discoveries are made.

John Hansen from Queensland Australia on August 30, 2016:

I have always been interested in dinosaurs since I was a young child and even considered studying palaeontology after leaving school, so I would have enjoyed this exhibit New species are being discovered all the time and the recent finding that many may have had feathers is interesting. I must say the model of the Dakotaraptor is hard to accept as what that dinosaur may have looked like. Good hub, Linda.

Linda Crampton (author) from British Columbia, Canada on August 29, 2016:

Thank you so much for the kind comment, Flourish. I appreciate both the comment and the share a great deal. The children that I saw at the PNE were very interested in the dinosaurs. So were the adults!

FlourishAnyway from USA on August 29, 2016:

between the review and the detailed information on the dinosaurs, you have truly outdone yourself on this one! the photos make me think that kids would love this place and they do need a guide to provide information and answer questions. Sharing!

Linda Crampton (author) from British Columbia, Canada on August 29, 2016:

Thanks for the comment and the share, Jackie. Many of the dinosaurs must have been majestic in their natural settings. I wish there was a way to go back in time to see them. I've never seen any of the Land Before Time films. I should find out what I've been missing!

Jackie Lynnley from the beautiful south on August 29, 2016:

Very interesting! I was just watching Land Before Time again last night, lol, that is the preferable ones to me. They are beautiful though and I can imagine how majestic they were in their natural settings long ago.


Linda Crampton (author) from British Columbia, Canada on August 29, 2016:

Hi, Nell. I can understand why you're a dinosaur fan. They are fascinating and mysterious creatures. Thanks for the visit.

Nell Rose from England on August 29, 2016:

How cool! I would love to go there! I was a great dinosaur fan when small, I used to collect loads of models and write all about them in my school books! lol!

Linda Crampton (author) from British Columbia, Canada on August 29, 2016:

Hi, Dianna. Thank you very much for the comment. I'd like to see the exhibit in other areas to compare it to the Vancouver version. I noticed that the PNE exhibit had several dinosaurs discovered in Canada. It would be interesting to see what models were included in other areas.

Dianna Mendez on August 29, 2016:

I viewed this exhibit at the Cincinnati Museum and thought it was impressive. Putting them outdoors really gives them almost a sense of reality. I would love to see this at the PNE. Your background on the dinosaurs is educational and interesting.

Linda Crampton (author) from British Columbia, Canada on August 29, 2016:

It is an interesting exhibit. I'm glad that I'm able to see it. Thanks for the visit, Bill.

Bill Holland from Olympia, WA on August 29, 2016:

What a great exhibit!!!! I would absolutely love to see that. Thanks for taking me along so I could snap some pictures in my mind.

Linda Crampton (author) from British Columbia, Canada on August 29, 2016:

Hi, Buildreps. Thanks for the comment. The thought of a dinosaur with feathers is strange but very interesting. I hope we discover a lot more about animals from the past.

Buildreps from Europe on August 29, 2016:

Fascinating article, Alicia. The idea that dinosaurs like the T-rex or Dakotaraptor might have feathers must have looked funny to us, after we've got used to the Hollywood movies. I can't somehow get used to the idea that these quite heavy animals could run that fast, but on the other hand is it for us humans almost impossible to outrun an elephant. Thanks for the nice article!
