Priconodon crassus
Sign in to savePriconodon (meaning "saw cone tooth") is an extinct genus of ankylosaurian dinosaur (perhaps nodosaurid), mainly known from its large teeth. Its remains have been found in the Early Cretaceous (Aptian-Albian age) Arundel Formation of Muirkirk, Prince George's County, Maryland, USA, and possibly the Potomac Group, also located in Maryland. As an ankylosaur, Priconodon would have been a large armored quadrupedal herbivore, though no size estimation has been done due to the scarcity of described remains.

Priconodon (meaning "saw cone tooth") is an extinct genus of ankylosaurian dinosaur (perhaps nodosaurid), mainly known from its large teeth. Its remains have been found in the Early Cretaceous (Aptian-Albian age) Arundel Formation of Muirkirk, Prince George's County, Maryland, USA, and possibly the Potomac Group, also located in Maryland. As an ankylosaur, Priconodon would have been a large armored quadrupedal herbivore, though no size estimation has been done due to the scarcity of described remains.
==History of discovery== O. C. Marsh named the genus for USNM 2135, a large worn tooth from what was then called the Potomac Formation. As ankylosaurians were by and large unknown at the time, he compared it to Diracodon (=Stegosaurus) teeth. It was not identified as an ankylosaurian until Walter Coombs assigned it to Nodosauridae in 1978.
