Ostracotheridae
Ostracotheridae is an extinct family of Mesozoic mammals belonging to the order Multituberculata. These small, rodent-like creatures lived during the Cretaceous period and into the early Paleogene. Fossil evidence suggests they were widespread across North America and Eurasia.

Their molars typically possessed multiple cusps arranged in a specific pattern, which gave the order its name.
The exact diet and lifestyle of Ostracotheridae are not definitively known, but based on their dentition and
