Notostylops

Notostylops ("south pillar face") is a genus of extinct South American ungulates from Eocene Argentina. Fossils of the genus have been found in the Sarmiento, Casamayor, Andesitas Huancache and Koluel Kaike Formations.
Description.
"Notostylops" was a very generalized animal, very similar to first eutherians and ungulates. It would have resembled a raccoon or weasel and is suspected to have browsed on low-growing plants. It was probably adapted to a fairly wide range of ecological niches, but its robustness indicates it had same digging traits. Its tall skull housed rodent-like incisor teeth. "Notostylops" was about long.
