Meaning of the name: Tooth with three bumps
Thrinaxodon is one of the most studied cynodonts. It lived about 250 million years ago. Thrinaxodons can be considered ancestors of mammals, or at least they are very close to the true ancestors. These were carnivorous animals no longer than half a meter, combining features of both mammals and reptiles. Thrinaxodons likely had fur. The dentition suggests that it was a carnivorous animal, feeding mainly on insects, small herbivores, and invertebrates. One innovation of Thrinaxodon was the secondary palate - a complete cranial partition between the nasal passage and the throat. This allowed the small creature to chew without interrupting its breathing, which was an important milestone in the evolution of mammals, later changing their digestion and metabolic rate. Thrinaxodon's body structure was light, reminiscent of modern martens in proportions, with an elongated and highly flexible torso in the horizontal plane. Judging by the large eye sockets, Thrinaxodon likely hunted primarily at night.
