Tritylodontidae

Tritylodontidae refers to a family of extinct cynodont therapsids, which are relatives of mammals. The genus Tritylodon is part of this family and its fossils are found in Late Triassic and Early Jurassic rocks, dating back to approximately 208 to 200 million years ago.1

Key characteristics of tritylodonts include:
* Dentition: A distinct gap separates the front incisors from complex cheek teeth that have two to four rows of cusps arranged lengthwise.1
* Skeletal Structure: In skull and general skeletal construction, they closely resembled true mammals.1
* Jaw Articulation: Unlike mammals, their lower jaw retained components from earlier amniotes, rather than the single dentary bone characteristic of mammals.1

It is believed that tritylodonts likely had habits similar to later rodents and multituberculates.1
