Although dinosaurs were the largest land animals of all time, a majority of them were smaller than a turkey!

Birds are believed to be the direct descendants of dinosaurs and therefore the only living dinosaurs today.The largest land dinosaurs like the brachiosaurus and the diplodocus also had the smallest brains!

The Stegosaurus’s brain was only as large as a walnut.

Some scientists believe there were over 800 different species of dinosaurs.The smallest dinosaur was the Compsognathus, which was the size of a chicken and had a very long tail. It ran after insects.

The Utahraptor may have been the deadliest dinosaur. It was a swift-running raptor with a huge claw on the middle toe of each foot.

Elasmosaurus lived in the sea and probably paddled along near the surface of the water. It was about 46 feet long, but more than half of its body length was a snakelike neck that could whip into the water to snap up fish.

The largest dinosaurs were over 100 feet (30 m) long and up to 50 feet (15 m) tall
