I don’t know much about dinosaurs but I have a mate that does! His name is Alec and he is 11 years old. He has loved dinosaurs and animals for ages – like lots of you! I have asked Alec to help me write about the dinosaurs here at Taronga.

Here’s what he had to say about our Dinosaur Profile for November – Deinonychus!

Deinonychus was a species of raptor that lived in the early Cretaceous period (which was 145 million years ago and a much nicer place and time than the late Cretaceous at 65 million years ago). It was about as big as a fully grown Labrador, ate meat and lived large. It was about 3.4 metres long and was commonly found in the USA. It was closely related to the Velociraptor and had feathers.

It had enough bite force to break through bone, which it might have done. It had 70 curved teeth to slice and dice flesh into bite-sized meals. It was a pack hunter like most raptors, and therefore had a large social sense. If you don't know what that means, it means it likes to talk to its friends in a special language, in a dino-like way.

Most raptors and other predators are nocturnal, that means they hunt at night to have a better chance of surprising prey. Modern day reptiles, like the dinosaurs, are cold blooded; they rely on sunlight to stay active and alive.

See you next month readers!
