They are also the dominant types in the oldest adequately known reptilian fauna and possess many archaic features which illustrate the structure of the primitive reptilian stock. Most of the earlier work on pelycosaurs was done by Cope. He realized...

... as the track of a cotylosaur. It occurs together with the track of Gilmoreichnus kablikae , which is either a captorhinomorph or possibly a juvenile pelycosaur. These facilitate the assignment of a late Early Permian (late Autunian) age to the strata. The third set of footprints, those of a small herbivorous...

These ichnotaxa suggest the presence of temnospondyls, seymouriamorphs, diadectomorphs, araeoscelids, captorhinids and synapsid pelycosaurs as potential trackmakers. These faunas correlate to the late early Permian. Two ichnoassociations correspond to two different...
