THE CONTINENTAL TETRAPOD-BEARING TRIASSIC OF SOUTH BRAZIL
The Rosario do Sul Group is one of the better-known tetrapod-bearing continental deposits of Triassic age. It crops out in central Rio Grande do Sul, south Brazil, and has yielded a fauna of more
An unusual new archosauriform from the Middle–Late Triassic of southern Brazil and the monophyly of Doswelliidae
TLDR
The phylogenetic analysis indicates that Doswellidae is the closest large monophyletic entity to Archosauria, which achieved a wide palaeolatitudinal distribution during the late Middle and Late Triassic time span.
BIOESTRATIGRAPHY OF SOUTHERN BRAZILIAN MIDDLE-UPPER TRIASSIC
The rocks of Middle/Upper Triassic from Southern Brazil (Parana Basin) can be divided in three major and clearly distinct biostratigraphic units from the basis to the top: 1) Therapsid Cenozone,
Redescription and phylogenetic relationships of Meridiosaurus vallisparadisi, a pholidosaurid from the Late Jurassic of Uruguay
TLDR
A phylogenetic analysis confirmed the monophyly of Pholidosauridae, and a new definition is proposed: a stem-based group name including Pholidosaurus schaumburgensis Meyer, 1841 and all taxa closer to it than to Dyrosaurus phosphaticus or Pelagosaurus typus Bronn, 18 41.
Study of a digital cranial endocast of the non-mammaliaform cynodont Brasilitherium riograndensis (Later Triassic, Brazil) and its relevance to the evolution of the mammalian brain
TLDR
The proposition of an early evolution of the mammalian brain associated with selective pressures for better sensorial acuity is supported, especially regarding improved olfaction, which began with small Triassic mammaliamorphs.
A new rhynchosaur from south Brazil (Santa Maria Formation) and rhynchosaur diversity patterns across the Middle-Late Triassic boundary
The rhynchosaur previously referred to as the “Mariante Rhynchosaur” is here formally described as a new genus and species based on two specimens: a complete skull (without the lower jaw) articulated
A New Specimen of Caiman brevirostris (Crocodylia, Alligatoridae) from the Late Miocene of Brazil
TLDR
The holotype materials of this species and a new specimen from the late Miocene of southwestern Amazonia, Brazil are presented and the diagnosis was expanded, and a phylogenetic analysis was conducted, returning results that consistently recover Caiman brevirostris within a clade that includes Caiman latrostris, Caiman cf.
