The postcranial skeleton of the family Limnoscelidae and its taxonomic implications for understanding basal amniotesWideman, Natalia Kazimiera 01 January 2002 (has links)
The Diadectomorpha is a central taxon in understanding the origin and early evolution of amniotes. It is considered a sister taxon to Amniota and is so similar to amniotes that some researchers have placed it within the Amniota itself. This group is composed of three families: the Limnoscelidae, the Tseajaiidae, and the Diadectidae. Being the most basal member of this group, the family Limnoscelidae is especially important in these studies.

A reinterpretation of the small Captorhinid Reptile Captorhinikos Parvus Olson as a new genus, reanalysis of its cranial anatomy, and a phylogenetic analysis of the basal reptilian family CaptorhinidaeAlbright, Gavan McBride 01 January 2003 (has links)
The cranial anatomy of the basal captorhinid reptile Captorhinikos parvus (Reptilia, Captorhinidae), is reinterpreted here based on analysis of a group of new specimens recovered subsequent to its original diagnosis as well as further analysis of the original specimens utilized in E.C. Olson's original characterization of the species. Structural features inconsistent with the generic description suggest the redefinition of C. parvus as a new genus, Rhodotheratus parvus. Analyses of basal members and selected derived members support the characterization of Rhodotheratus as a distinct taxon.
