Cranial anatomy of Emeroleter levis and the phylogeny of Nycteroleteridae.
Autor: Kayla D Bazzana-Adams, Mark J MacDougall, Jörg Fröbisch
Publikováno v: PLoS ONE, Vol 19, Iss 4, p e0298216 (2024)
Among the diverse basal reptile clade Parareptilia, the nycteroleters are among the most poorly understood. The interrelationships of nycteroleters are contentious, being recovered as both monophyletic and paraphyletic in different analyses, yet thei

Ontogenetic Change in the Temporal Region of the Early Permian Parareptile Delorhynchus cifellii and the Implications for Closure of the Temporal Fenestra in Amniotes.
Autor: Yara Haridy, Mark J Macdougall, Diane Scott, Robert R Reisz
Publikováno v: PLoS ONE, Vol 11, Iss 12, p e0166819 (2016)
A juvenile specimen of Delorhynchus cifellii, collected from the Early Permian fissure-fill deposits of Richards Spur, Oklahoma, permits the first detailed study of cranial ontogeny in this parareptile. The specimen, consisting of a partially articul

Plicidentine in the Early Permian parareptile Colobomycter pholeter, and its phylogenetic and functional significance among coeval members of the clade.
Autor: Mark J MacDougall, Aaron R H LeBlanc, Robert R Reisz
Publikováno v: PLoS ONE, Vol 9, Iss 5, p e96559 (2014)
Once thought to be an exclusively anamniote characteristic, plicidentine, a pattern of infolding of dentine, is now known to be found in various amniote clades, including Parareptilia. In the absence of detailed analyses of parareptilian dentition, m

Revised Description of the Early Permian Recumbirostran 'Microsaur' Nannaroter mckinziei Based on New Fossil Material and Computed Tomographic Data
Autor: Diane Scott, Jörg Fröbisch, Robert Seeger, Bryan M. Gee, Joseph J. Bevitt, Mark J. MacDougall, Maren Jansen, Robert R. Reisz, Jasper Ponstein
Publikováno v: Frontiers in Ecology and Evolution, Vol 9 (2021)
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. We present a new p

Publikováno v: Frontiers in Ecology and Evolution, Vol 9 (2021)
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 footprint record of reptiles

Conflicting evidence for the use of caudal autotomy in mesosaurs
Autor: Jörg Fröbisch, Vincent Fernandez, Aaron R. H. LeBlanc, Mark J. MacDougall, Antoine Verrière, Tanja Wintrich
Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-9 (2020)
'Scientific Reports ', vol: 10, pages: 7184-1-7184-9 (2020)
Scientific Reports
The early Permian mesosaurs were the first amniotes to re-invade aquatic environments. One of their most controversial and puzzling features is their distinctive caudal anatomy, which has been suggested as a mechanism to facilitate caudal autotomy. S

Publikováno v: Journal of Environmental Management. 201:407-424
Cumulative effects assessment (CEA) - a type of environmental appraisal - lacks effective methods for modeling cumulative effects, evaluating indicators of ecosystem condition, and exploring the likely outcomes of development scenarios. Random forest

Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 475:1-11
The Richards Spur locality, Oklahoma, USA, represents an Early Permian infill in a series of Ordovician limestone and dolostone karst fissures. It exhibits the most diverse terrestrial Palaeozoic community currently known, with > 40 distinct tetrapod
