DINO FACTS :
One of the most intelligent dinosaurs was Troodon. It was a hunting dinosaur, about 2 metres long, and had a brain size similar to that of a mammal or bird of today, stereoscopic vision, and grasping hands.
The oldest known dinosaur is Saltopus. It was a small carnivore that lived 245 million years ago. Remains of this dinosaur have only been found in Scotland, so the UK might hold the key to the origin of dinosaurs.
The speediest dinosaurs were the ostrich mimic ornithomimids, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour.
