Colobomycter

Colobomycter is an extinct genus of acleistorhinid parareptile known from the Early Permian of Oklahoma.

== Discovery == The type species, Colobomycter pholeter, was first described from fossil remains in 1958, at which time it was believed to represent a synapsid, specifically, a pelycosaur. However, the discovery of new material and reexamination of the holotype led to its reclassification as a member of the Eureptilia. More recent studies indicate that Colobomycter is properly placed within the amniote clade Parareptilia, as part of the group Lanthanosuchoidea and closely related to the taxon Acleistorhinus. A second species of Colobomycter was described in 2016, Colobomycter vaughni.
