A Unique Late Triassic Dinosauromorph Assemblage Reveals Dinosaur Ancestral Anatomy and Diet
This is the first time nearly complete dinosaur and non-dinosaur dinosauromorph remains are found together in the same excavation, clearly showing that these animals were contemporaries since the first stages of dinosaur evolution. Expand
Middle–Late Permian tetrapods from the Rio do Rasto Formation, Southern Brazil: a biostratigraphic reassessment
Dias-da-Silva, S. 2011: Middle–Late Permian tetrapods from the Rio do Rasto Formation, Southern Brazil: a biostratigraphic reassessment. Lethaia, Vol. 45, pp. 109–120. The Rio do RastoExpand
A new Permian temnospondyl with Russian affinities from South America, the new family Konzhukoviidae, and the phylogenetic status of Archegosauroidea
This taxon is considered to be a nomen dubium and purge it from the strict consensus tree, and the phylogenetic results support the erection of a new family – Konzhukoviidae – to replace ‘Tryphosuchinae’ and accommodate Konz hukovia vetusta, K. tarda and K. sangabrielensis, the new Brazilian species basal to the Russian forms.

New postcranial elements of the Thalassodrominae (Pterodactyloidea, Tapejaridae) from the Romualdo Formation (Aptian–Albian), Santana Group, Araripe Basin, Brazil
New postcranial material from the Romualdo Formation (Aptian-Albian) from the Araripe Basin is described, which is the most complete postc Cranial material assigned to the Thalassodrominae described so far. Expand
A new aetosaur from the Upper Triassic of the Santa Maria Formation, southern Brazil.
A new Late Triassic juvenile aetosaur from the Santa Maria Formation of southern Brazil is described, increasing the paleobiodiversity of this interesting group to five taxa in Western Gondwana. Expand
The oldest known co-occurrence of dinosaurs and their closest relatives: A new lagerpetid from a Carnian (Upper Triassic) bed of Brazil with implications for dinosauromorph biostratigraphy, early
Abstract Late Triassic deposits from south Pangea (Argentina and Brazil) bear the oldest (so far) and most informative unequivocal records of dinosaurs worldwide. Herein we describe a new lagerpetidExpand
The femoral anatomy of Pampadromaeus barberenai based on a new specimen from the Upper Triassic of Brazil
Femora of the holotype and only previously known specimen of the early sauropodomorph Pampadromaeus barberenai are incomplete and fractured. Here, we describe a new complete femur assigned toExpand
New material of Procolophon (Parareptilia: Procolophonoidea) from the Lower Triassic of Brazil, with remarks on the ages of the Sanga do Cabral and Buena Vista formations of South America
We describe a large, fragmentary procolophonid skull and three large vertebrae from the Sanga do Cabral Formation, Parana Basin, Lower Triassic of Brazil. Cranial and dental morphology allow us to ...
Prozostrodon brasiliensis, a probainognathian cynodont from the Late Triassic of Brazil: second record and improvements on its dental anatomy
The second known specimen (CAPPA/UFSM 0123) of Prozostrodon brasiliensis is described, showing that the adult individual has more postcanine tooth morphotypes than the juvenile one. Expand
Phylogenetic reappraisal of Rhytidosteidae (Stereospondyli: Trematosauria), temnospondyl amphibians from the Permian and Triassic
Increasing efforts to collect Upper Permian and Lower Triassic rhytidosteids should help to improve stratigraphical, palaeogeographical and phylogenetic information regarding this widespread group of temnospondyls. Expand
