The discovery of an amphibamid temnospondyl from the Early Permian of Texas that bridges the gap between other Palaeozoic amphibians and the earliest known salientians and caudatans from the Mesozoic is reported.
A reevaluation of early amniote phylogeny
It is indicated that three major clades of amniotes extend from the present to the Palaeozoic, and these three clades are the Synapsida (including Mammalia), Parareptilia (including Testudines), and Eureptili (including Sauria).
The first articulated skeleton of Dendrerpeton acadianum (Temnospondyli, Dendrerpetontidae) from the Lower Pennsylvanian locality of Joggins, Nova Scotia, and a review of its relationships

Although Dendrerpeton bears a general resemblance to the highly terrestrial dissorophoid temnospondyls and even shares with them a large squamosal embayment supported ventrally by the quadratojugal and a quadrate process, phylogenetic analysis does not support a sister-group relationship.

It is plea for closer interactions between paleontologists and molecular biologists in studying the timescale of vertebrate evolution and proposes three qualitative, phylogenetic criteria that can be used within a comparative framework for the selection of well-constrained calibration dates from the vertebrate fossil record.
GAINING GROUND: THE ORIGIN AND EVOLUTION OF TETRAPODS
- R. Reisz
- Environmental Science
- 12 September 2003
This book is a timely, well written addition to the paleontological literature, and represents an outstanding effort to introduce the reader to the rather complicated story of the origin of fourlimbed vertebrates and their gradual, initial colonization of land.
THE ORIGIN AND EARLY EVOLUTION OF TURTLES
- O. Rieppel, R. Reisz
- Environmental Science
- 1 November 1999
A critical reexamination of turtle relationships continues to support a sister-group relationship of turtles with a clade of marine reptiles, Sauropterygia, within crown-group Diapsida (Sauria), and an aquatic origin of turtles is suggested.
The Oldest Caseid Synapsid from the Late Pennsylvanian of Kansas, and the Evolution of Herbivory in Terrestrial Vertebrates

These results demonstrate for the first time that large caseid herbivores evolved from small, non-herbivorous caseids, and are mirrored by three other clades, documenting multiple, independent, but temporally staggered origins of herbivory and increase in body size among early terrestrial tetrapods, leading to patterns consistent with modern terrestrial ecosystem.
Cranial Anatomy of Ennatosaurus tecton (Synapsida: Caseidae) from the Middle Permian of Russia and the Evolutionary Relationships of Caseidae
Phylogenetic analysis of Caseidae yields a single most parsimonious tree and its topology reveals that the pattern of dental complexity in terms of the number of apical cuspules is homoplasious, cautioning against its use as a unidirectional phylogenetic character.
