Cisneros, Juan Carlos
MetadataShow full item record
Anomodontia was a highly successful tetrapod clade during the Permian and the Triassic. New morphological information regarding two bizarre basal anomodonts is provided and their palaeoecological significance is explored. The osteology of the recently discoveredTiarajudens eccentricusCisneroset al. 2011, from the Brazilian Permian, is described in detail. The taxon exhibits unusual postcranial features, including the presence of gastralia. Additional preparation and computed tomography scans of the holotype of Anomocephalus africanusModesto et al. 1999 discovered in the Karoo Basin of South Africa allow a reappraisal of this genus.
