ABSTRACT We describe four newly discovered and three-dimensionally preserved specimens of the discosauriscid seymouriamorph Discosauriscus pulcherrimus from the Lower Permian lacustrine sediments of the Boskovice Basin (Czech Republic). Their excellent preservation revealed new cranial features that allowed us to present a new skull reconstruction of middle-sized specimens of this tetrapod. The new features include: (1) the sculpturing of the anterior wedge-like process of the parasphenoid consisting ...

The Upper Permian seymouriamorph tetrapod Karpinskiosaurus from European Russia includes two species: Karpinskiosaurus secundus and Karpinskiosaurus ultimus. Karpinskiosaurus secundus is represented by two specimens with skull lengths of about 75 mm. All specimens of K. ultimus are smaller than those of K. secundus. Revision of the cranial anatomy of all previously known and several new specimens of Karpinskiosaurus shows that the specimens of K. secundus and most of the specimens of K. ultimus ...

ABSTRACT Two nearly complete, articulated, mature specimens of the amphibian Seymouria are described from the Lower Permian Tambach Formation, lowermost unit of the Upper Rotliegend, of the Bromacker locality in the mid-region of the Thuringian Forest near Gotha, central Germany. They are assigned to S. sanjuanensis, known elsewhere only from the Lower Permian deposits of Wolfcampian age in the southwestern United States. This confirms an earlier referral of two immature specimens from the same ...

Isolated skeletal elements of the amphibian genus Seymouria were recently discovered at the Richards Spur locality near Fort Sill, Oklahoma, a prolific source of Early Permian tetrapod remains. Five of the seven described bones are of juvenile size and include three neural arches, a humerus, and a femur, whereas the other two are partial vertebrae, apparently adult. All seven are morphologically similar to equivalent skeletal elements in Seymouria specimens previously collected in Europe and North ...

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 ...
