Diversity patterns of nonmammalian cynodonts (Synapsida, Therapsida) and the impact of taxonomic practice and research history on diversity estimates

Lukic-Walther, Marcus; Brocklehurst, Neil; Kammerer, Christian; Fröbisch, Jörg

Nonmammalian cynodonts represent a speciose and ecologically diverse group with a fossil record stretching from the late Permian until the Cretaceous. Because of their role as major components of Triassic terrestrial ...

Novel Endocranial Data on the Early Therocephalian Lycosuchus vanderrieti Underpin High Character Variability in Early Theriodont Evolution

Pusch, Luisa C.; Ponstein, Jasper; Kammerer, Christian; Fröbisch, Jörg

Therocephalia is one of the major therapsid clades and ranges from the middle Permian to Middle Triassic. The earliest therocephalians were large-bodied predators whose fossils are common in middle Permian rocks of South ...

Regionalization, constraints, and the ancestral ossification patterns in the vertebral column of amniotes

Verrière, Antoine; Fröbisch, Nadia; Fröbisch, Jörg

The development of the vertebral column has been studied extensively in modern amniotes, yet many aspects of its evolutionary history remain enigmatic. Here we expand the existing data on four major vertebral developmental ...

Revised Description of the Early Permian Recumbirostran “Microsaur” Nannaroter mckinziei Based on New Fossil Material and Computed Tomographic Data

MacDougall, Mark J.; Seeger, Robert; Gee, Bryan; Ponstein, Jasper; Jansen, Maren; Scott, Diane; Bevitt, Joseph; Reisz, Robert; Fröbisch, Jörg

The early Permian Richards Spur locality of Oklahoma has produced abundant material of numerous terrestrial fossil tetrapods, including various “microsaurs,” several of which are considered to belong to the clade Recumbirostra. ...

The Definition of Bioregions in Palaeontological Studies of Diversity and Biogeography Affects Interpretations

Brocklehurst, Neil; Fröbisch, Jörg

Studies of diversity, whether of species richness within regions (alpha diversity) or faunal turnover between regions (beta diversity), will depend heavily on the “bioregions” into which a study area is divided. However, ...

The postcranial anatomy of Gorgonops torvus (Synapsida, Gorgonopsia) from the late Permian of South Africa

Bendel, Eva-Maria; Kammerer, Christian; Smith, Roger M. H.; Fröbisch, Jörg

Gorgonopsians are among the most recognizable groups of synapsids from the Permian period and have an extensive but mostly cranial fossil record. By contrast, relatively little is known about their postcranial anatomy. ...

Marchetti, Lorenzo; Voigt, Sebastian; Buchwitz, Michael; MacDougall, Mark J.; Lucas, Spencer G.; Fillmore, David L.; Stimson, Matthew R.; King, Olivia A.; Calder, John H.; Fröbisch, Jörg

The origin of Reptilia and the biostratigraphic and palaeobiogeographic distribution of its early representatives are still poorly understood. An independent source of information may come from the extensive Carboniferous ...
