酷東西

趣味知識

Anodontosaurus had a wide, pointed tail club made of bone that it could swing to defend itself.1

Its skull had small polygonal plates of bone behind the eye, called postocular caputegulae.1

The name 'toothless lizard' was a mistake: the first fossil had its teeth crushed and hidden, so the scientist thought it had no teeth.1

Anodontosaurus lived between about 75.6 and 67 million years ago, during the Late Cretaceous.1

There are two species of Anodontosaurus: A. lambei and A. inceptus.1

For many years scientists thought Anodontosaurus was the same as another ankylosaur called Euoplocephalus, but later studies showed it was a different genus.1
