Species
Clepsydrops limbatus
Clepsydrops limbatusDimetrodon limbatus roamed early Permian equatorial floodplains as one of the earliest dominant terrestrial apex predators. Towering neural spines supported an expansive dorsal sail, deeply scored with grooves for blood vessels that likely assisted in rapid thermoregulation and visual courtship displays. Its differentiated heterodont teeth allowed it to easily shear through the tough hide of contemporary amphibians and early reptiles.

Responsible observation
- Museum Exhibits: Examine Permian red-bed skeletal mounts to see the distinct heterodont teeth.
- Fossil Viewing: Look for fine vascular channels preserved along the elongate neural spines.
