Carbonodraco is the oldest known parareptile, and is slightly older than Erpetonyx, the previously oldest known parareptile. Specimens of Carbonodraco are limited to skull and jaw fragments found at the Ohio Diamond Coal mine in Linton, Ohio.
Acleistorhinus (ah-kles-toe-RYE-nuss) is an extinct genus of parareptile known from the Early Permian (middle Kungurian stage) of Oklahoma. [1] It is notable for being the earliest known anapsid reptile yet discovered.
Parareptilia ("near-reptiles") is an extinct subclass or clade of basal sauropsids/reptiles, typically considered the sister taxon to Eureptilia (the group that likely contains all living reptiles and birds).

However, Hylonomus, the oldest eureptile known from fossil evidence, lived millions of years before parareptiles appeared in the fossil record. The discovery of Erpetonyx helped to shorten this gap between parareptile and eureptile fossils, as Erpetonyx lived in the Late Carboniferous and is one of the oldest known parareptiles (though ...
