酷東西

趣味知識

Tototlmimus is the first ornithomimid dinosaur formally named from Mexico.1

Its fossils were found in the Packard Shale, which is about 72 million years old.1

Only parts of the hands and feet have been discovered, so scientists don't know its full size.2

The name Tototlmimus comes from the Nahuatl word 'tototl' meaning bird, and 'mimus' meaning mimic.1

Its foot bones show it had an arctometatarsus, a special structure that helped it run fast.1

Tototlmimus lived on the ancient continent of Laramidia, which is now western North America.2
