Argentinastruthio

Argentinastruthio is an extinct species of theropod part of the extinct group, Ornithomimosaurs (aka Ornithomimids), that lived in what is now Argentina in South America, during the Late Cretaceous from 71 million years ago to 66 million years ago. Its fossilized skin discovered in the Salta Formation suggests that, unlike most other Ornithomimids, Argentinastruthio was completely scaly, possibly due to the area they lived in probably being much hotter than the Sahara Desert of today, but the fossilized skin was discovered to be on its leg, so it is possible that its torso, arms, tail, and head could have been feathered, but no one knows for sure yet until more skin fossils of Argentinastruthio in different parts of their bodies have been unearthed. They were most likely herbivorous, but may have had fed on worms, insects, eggs (unlike most other Ornithomimids), and small mammals, making it an omnivore instead of just a herbivore. They were named when its fossils were first discovered in 1933, they were first thought to be ostriches that escaped from circuses in 1800s, until complete skeletons were discovered, confirming that they weren't ostriches nor were they birds. It is unknown why Argentinastruthio became extinct suddenly.
