Secodontosaurus

Secodontosaurus was a pelycosaur that lived in Texas during the Early Permian age. Though it had the same body style as other sphenacodontids, it had an unusually low and narrow skull. It had a long neural spines, like Dimetrodon, which Secodontosaurus was related to. The cranial modifications of Secodontosaurus indicate an adaptation to some specialized feeding strategy, perhaps preying upon burrowing animals, or perhaps aquatic feeding habits.
