趣味知識

Chenanisaurus is one of the last dinosaurs known from Africa before the asteroid hit 66 million years ago.2

Its fossils were found in a phosphate mine, which is a marine rock layer. Finding a dinosaur there is like finding a lion while hunting for whales.2

Chenanisaurus had a deep, short lower jaw, even deeper than in the related dinosaur Carnotaurus.1

It had at least ten teeth in its lower jaw, and the front teeth were D-shaped while the back ones were flat and dagger-like.1

This dinosaur was about 7 to 8 metres long, similar in size to Carnotaurus and Pycnonemosaurus.1

Chenanisaurus had very short arms, with a short upper arm bone, an even shorter lower arm, and tiny hands.2

Unlike the partly feathered T. rex, Chenanisaurus had only scales and a smaller brain.2
