The ornithomimidae were mostly scattered across Asia and North America during the late Cretaceous period, approximately between 100.5 and 66 million years ago
They had small heads, long necks, and arms covered with feathers, had no teeth, and had long legs.
This new species, Tototlmimus packardensis, was named as such by the team at the National Autonomous University of Mexico, led by paleontologist Claudio Ines Serrano-Brañas.
Although they only found fragments of the skeleton, including parts of the hands and feet, this has been enough evidence to differentiate it from other members of the same family. The Tototlmimus has five unique anatomical details in its leg’s bones, which distinguishes it from other ornithomimidae.
It is noteworthy that the name Tototlmimus comes from the Nahuatl word “tototl” which means bird.
This specimen seems to have lived about 72 million years ago, and their fossils were found in Sonora, northwestern Mexico, and is the only dinosaur of its kind ever found in the country.
