Cranial Anatomy of Ennatosaurus tecton (Synapsida: Caseidae) from the Middle Permian of Russia and the Evolutionary Relationships of Caseidae
Abstract Detailed description of the Middle Permian Russian caseid Ennatosaurus tecton shows that three autapomorphies distinguish it from other caseids: a broad anterior ramus of the jugal, a large… Expand

Evolution of the Amphibian Ear with Implications for Lissamphibian Phylogeny: Insight Gained from the Caecilian Inner Ear
Abstract The inner ear is a complex structure consisting of the vestibular and auditory systems. Across vertebrates, morphological variation in the inner ear provides a source of homologous features… Expand

Reappraisal of the Early Permian amphibamid Tersomius texensis and some referred material
Abstract The accuracy of the taxonomic assignment of three skulls in the collections of the Museum of Comparative Zoology (Harvard University) to the Early Permian taxon Tersomius texensis has been… Expand

A redescription of Carrolla craddocki (Lepospondyli: Brachystelechidae) based on high‐resolution CT, and the impacts of miniaturization and fossoriality on morphology
Some recent morphological analyses have brought into question the monophyly of Lissamphibia (frogs, salamanders, and caecilians). In these analyses, brachystelechid “microsaurs” are found to be… Expand

Histological microstructure of the claws of the African clawed frog, Xenopus laevis (Anura: Pipidae): implications for the evolution of claws in tetrapods.
Claws are consistent components of amniote anatomy and may thus be implicated in the success of the amniote invasion of land. However, the evolutionary origin of these structures in tetrapods is… Expand

The Braincase of Eocaecilia micropodia (Lissamphibia, Gymnophiona) and the Origin of Caecilians
The scant fossil record of caecilians has obscured the origin and evolution of this lissamphibian group. Eocaecilia micropodia from the Lower Jurassic of North America remains the only stem-group… Expand

AN EARLY PERMIAN VARANODONTINE VARANOPID (SYNAPSIDA: EUPELYCOSAURIA) FROM THE RICHARDS SPUR LOCALITY, OKLAHOMA
Abstract Description of the first varanodontine varanopid material from the highly fossiliferous limestone fissure fill deposits at Richards Spur (Dolese Brothers Limestone Quarry), Oklahoma, is… Expand

Evolutionary development of the neurocranium in Dissorophoidea (Tetrapoda: Temnospondyli), an integrative approach
SUMMARY Ontogenetic data can play a prominent role in addressing questions in tetrapod evolution, but such evidence from the fossil record is often incompletely considered because it is limited to… Expand

The anatomy and development of the claws of Xenopus laevis (Lissamphibia: Anura) reveal alternate pathways of structural evolution in the integument of tetrapods
Digital end organs composed of hard, modified epidermis, generally referred to as claws, are present in mammals and reptiles as well as in several non‐amniote taxa such as clawed salamanders and… Expand

The morphology of the terminal phalanges in Permo-Carboniferous synapsids: an evolutionary perspective
Morphological features of the terminal phalanges of extinct tetrapods can be used to infer whether or not keratinous claws were present even though these structures are not preserved in the fossil… Expand
