Few Permian vertebrates are of greater interest than the one herewith figured, as restored from a remarkably complete specimen discovered the past year by Mr. Paul C. Miller in the vicinity of Seymour, Baylor County, Texas. The genus and species were originally described by Dr. Broili in 1904 from two imperfect skulls, the clavicular girdle, and a few of the anterior vertebrae and ribs, found on West Coffee Creek, Texas, and preserved in the museum at Munich. Nothing whatever has since been…

Postcranial anatomy and histology of Seymouria, and the terrestriality of seymouriamorphs
Seymouria is the best known of the seymouriamorphs, a group of Permo-Carboniferous reptiliomorphs with both terrestrial and aquatic taxa. The majority of research on Seymouria has focused on cranial
A reevaluation of Ariekanerpeton, a Lower Permian seymouriamorph (Vertebrata: Seymouriamorpha) from Tadzhikistan
This taxon is similar to Discosauriscus austriacus, and only three characters separate them: the absence of an interpterygoid vacuity, the loss of a phalanx in the fourth manual digit, and the absence in post-metamorphic specimens of Ariekanerpeton.
Morphology and Histology of Dorsal Spines of the Xenacanthid Shark Orthacanthus platypternus from the Lower Permian of Texas, USA: Palaeobiological and Palaeoenvironmental Implications
Detailed studies on Carboniferous species of the xenacanth Orthacanthus have shown that the xenacanth dorsal fin spine can be used for skeletochronological analyses and provides valuable information
Gnathostome vertebrae and the classification of the Amphibia
Four pairs of arcualia were primitively present in each segment of gnathostomes. The individual vertebral ossifications of early temnospondyls are most economically interpreted as the endochondral
