What was aparathid?

Aparathid is an extinct group of small to medium-sized mammals that belonged to the order of ungulates, specifically within the clade Perissodactyla, which includes modern horses, rhinos, and tapirs. They lived during the Paleocene to Eocene epochs, approximately 66 to 34 million years ago. Aparathids are characterized by their unique dental and skeletal features that distinguish them from other early ungulates. Fossil evidence suggests that they were herbivorous and adapted to various terrestrial environments.
