Paraplacosauriops (near Placosauriops) is an extinct genus of anguid lizards from the middle Eocene of France.

Taxonomy

[edit]

Paraplacosauriops was originally named Plestiodon quercyi by Filhol (1882) on the basis of dentary remains from fissure fill deposits in Quercy, France.[1] Hoffstetter (1944) referred P. quercyi to the glyptosaurine genus Placosaurus, which is likewise endemic to Europe.[2] However, Auge and Sullivan (2006) recognized quercyi as belonging to the tribe Melanosaurini and not a Placosaurus-like glyptosaurin, so they erected Paraplacosauriops for P. quercyi.[3]

Description

[edit]

Distinguishing features of Paraplacosauriops include a distinguishing heterodont dentition, especially the anterior teeth being extremely slender, pointed and not peg-like.[3]
