Pliogonodon is an extinct genus of crocodylomorph. The type species, P. priscus, was named by Joseph Leidy in 1856. The holotype, known as USNM 7448, is a worn and broken tooth found from Phoebus Landing on the Cape Fear River in North Carolina.[1] Although the age of the strata in which the tooth was found was not recorded, it is thought to have come from Miocene-age beds.[2] The holotype and another tooth found at the same location are all that is known from the genus. The genus is considered a nomen dubium because of the lack of diagnostic features possessed by the teeth, and has been suggested to be synonymous with the alligatoroid Deinosuchus.[3] Although Carroll (1988) assigned the genus to the basal neosuchian family Goniopholididae,[4] current consensus is that Pligonodon is a Deinosuchus specimen.[5]
The two teeth are conical and curve slightly inward, estimated to be around 2 inches (5.1 cm) in length if they had been fully preserved. The enamel is wrinkled and the base of the crowns are hollow.[2]
