A reevaluation ofAriekanerpeton, a Lower Permian seymouriamorph (Vertebrata: Seymouriamorpha) from Tadzhikistan (original) (raw)

Journal of Vertebrate Paleontology, 1996

Abstract

ABSTRACT Several specimens of Ariekanerpeton sigalovi are described and illustrated for the first time. This taxon is similar to Discosauriscus austriacus, and only three characters separate them: 1) the absence of an interpterygoid vacuity, 2) the loss of a phalanx in the fourth manual digit, and 3) the absence of dermal scales in post-metamorphic specimens of Ariekanerpeton. Both taxa are represented by larvae and juvenile post-metamorphic specimens, but no fully adult individuals. Ariekanerpeton and Discosauriscus share several derived characters with Seymouria and are considered to be closely related to the latter.
