Redescription of the holotype specimen of Cephalerpeton ventriarmatum
Moodie, 1912, from the Middle Pennsylvanian (Moscovian) Francis Creek Shale
of Mazon Creek, Illinois, confirms that it is a basal eureptile with close
postcranial similarities to other protorothyridids, such as Anthracodromeus
and Paleothyris. The skull is long and lightly built, with large orbits and
a dorsoventrally short mandible similar to most basal eureptiles. Two
specimens referred previously to Cephalerpeton cf. C. ventriarmatum from
the approximately coeval Linton, Ohio, locality differ significantly from
the holotype in cranial and mandibular proportions and tooth morphology.
This material and an additional Linton specimen compare favourably to
‘short-faced’ parareptiles, such as Colobomycter and Acleistorhinus, and
justify recognition of an acleistorhinid parareptile in the Linton
assemblage. The new binomen is thus the oldest known parareptile.
