Dinosaur species

Theropods A-Z

Allosaurus   A large meat-eating dinosaur from the Late Jurassic. It grew up to 12 metres (39 feet) long. It had sharp teeth and three big, clawed toes on each foot. It probably hunted in packs to bring down large prey. 

Archaeopteryx   A bird-dinosaur from the Jurassic Period. It is the earliest known bird. Like birds, it had feathers, wings and a small, light body. However, it had much more in common with theropods. Like them, it had strong jaws and sharp teeth, a long neck and stiff tail and three clawed fingers. It fed on meat, fish and insects.
