Procynosuchus delaharpeae
Procynosuchus delaharpeaeProcynosuchus delaharpeae was an agile, semi-aquatic cynodont that navigated Late Permian freshwater rivers and floodplains much like a modern otter. Its specialized skeleton featured flexible vertebral articulations, broad paddle-like feet, and a robust ribcage adapted for undulating through shallow water while hunting fast-moving prey. As one of the earliest known cynodonts, it possessed differentiated teeth and a developing secondary palate that allowed it to chew and breathe simultaneously.
