A stem batrachian from the Early Permian of Texas and the origin of frogs and salamanders
The origin of extant amphibians (Lissamphibia: frogs, salamanders and caecilians) is one of the most controversial questions in vertebrate evolution, owing to large morphological and temporal gaps in… Expand
A reevaluation of early amniote phylogeny
Abstract A new phylogenetic analysis of early amniotes based on 124 characters and 13 taxa (including three outgroups) indicates that synapsids are the sister-group of all other known amniotes. The… Expand
Four well-constrained calibration points from the vertebrate fossil record for molecular clock estimates.
Recent controversy about the use of the vertebrate fossil record for external calibration of molecular clocks centers on two issues, the number of dates used for calibration and the reliability of… Expand
Molecular timescales and the fossil record: a paleontological perspective.
Abstract The fossil record serves a crucial function as an external calibration for genomic clocks and molecular evolutionary timescales. Although certain portions of the vertebrate fossil record are… Expand
The first articulated skeleton of Dendrerpeton acadianum (Temnospondyli, Dendrerpetontidae) from the Lower Pennsylvanian locality of Joggins, Nova Scotia, and a review of its relationships
ABSTRACT The discovery of the first articulated, well-preserved specimen of Dendrerpeton acadianum makes it possible to describe this taxon completely for the first time, and reassess its… Expand

CHAPTER 2 – A NEW PERSPECTIVE ON TETRAPOD PHYLOGENY
This chapter provides an in-depth explanation of the origin of amniotes. It follows articles from various authors, especially those that compare hypotheses on the origin of lissamphibians where… Expand
THE ORIGIN AND EARLY EVOLUTION OF TURTLES
▪ Abstract 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… Expand
Owenetta kitchingorum, sp. nov., a small parareptile (Procolophonia: Owenettidae) from the Lower Triassic of South Africa
Abstract The parareptile Owenetta rubidgei is known from several skulls, all found in Upper Permian sediments of South Africa. The anatomy of a new species of Owenetta, O. kitchingorum, from the… Expand
