Sarcoprion (from the Ancient Greek, "flesh saw") is an extinct genus of eugeneodont holocephalan from the Permian of Greenland. Similar to other helicoprionids such as Agassizodus and Helicoprion, it possessed tooth whorls on the symphysis of the jaw as well as flattened, pavement-type teeth. It is distinguished from other members of its family by the presence of sharp, symphyseal teeth on both the upper and lower jaws. The tooth whorl on the lower jaw bore sharp, compact tooth crowns, while a row of backward facing, triangular teeth was present on the roof of the mouth. The preserved material does not show evidence of a distinct upper jaw, implying it may have been fused to the cranium, reduced, or lost entirely. The type and only species in the genus is S. edax.




Description



Sarcoprion had a thin, pointed snout, with proportionally small tooth whorls and a greatly elongated rostrum compared to its relatives for which comparable skull material is known. The most complete known specimen consists only of a partial cranium and lower jaws.
