Found in China, the Archaeornithomimus It is the oldest ornithomimidae or ostrich mimic dinosaur, which lived in the Cretaceous period 70 million years ago.

Unlike its later cousins, which had three long "toes" on each leg, Archaeornithomimus had a short, small toe, and all of its leg bones are much shorter than any other ornithomimid, as well as its hind legs were especially robust.

This finding has led some scientists to wonder if the Archaeornithomimus is a true ornithomimido or a new carnivorous dinosaur not yet identified.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news about archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
