Orretherium (say "Or-reh-THEER-ee-um") is an ancient mammal that lived a very long time ago. Its name means "Five teeth beast." Part of this name comes from the Aonikenk language, spoken by the Tehuelche people in South America. This animal lived in what is now Chile, in South America. It was around during the Late Cretaceous period, which was the very end of the time of the dinosaurs. Its fossils were found in a place called the Dorotea Formation.

What Was Orretherium?
Orretherium was a type of early mammal. It belonged to a group called mesungulatids. These were small, early mammals that lived alongside the giant dinosaurs. Scientists believe Orretherium was likely a small creature. It probably looked a bit like today's shrews or mice.
When Did Orretherium Live?
Orretherium lived during the Late Cretaceous period. This was about 83 to 66 million years ago. This time was the final part of the Mesozoic Era. It was when many famous dinosaurs like Tyrannosaurus rex and Triceratops were alive. Orretherium survived until the very end of this period.
Where Did Orretherium Live?
The fossils of Orretherium were found in Chile, a country in South America. Specifically, they were discovered in the Dorotea Formation. This area was likely a rich environment back then. It would have had plants and other small animals. This allowed early mammals like Orretherium to thrive.
Discovery of Orretherium
Orretherium was first described by scientists in 2021. This means it is a relatively new discovery. The scientists who studied it were led by Martinelli and his team. Finding fossils like Orretherium helps us learn more about early mammal life. It shows how mammals were evolving even when dinosaurs ruled the Earth.
Why Is Orretherium Important?
The discovery of Orretherium is important for several reasons. It helps us understand the diversity of early mammals. It also gives clues about how mammals spread across continents. Finding it in South America shows that these types of mammals were present there. This adds to our knowledge of ancient ecosystems.
