酷東西

趣味知識

Tochisaurus is known only from a single left foot bone, called a metatarsus.1

The foot bone is 242 millimetres long, making Tochisaurus a relatively large troodontid.1

Its second toe bone was very thin and reduced, so it probably walked on only two toes, like an ostrich.1 3

The name Tochisaurus comes from the Mongolian word for ostrich, because its foot looks like an ostrich's foot.1

Tochisaurus lived about 72 to 66 million years ago, during the Maastrichtian stage.2

It was a member of the Troodontidae family, a group of bird-like dinosaurs.1
