Palaeontology, Volume 69, Issue 2, 2026.Abstract There is a growing consensus that pterosaurs and the flightless Lagerpetidae are closely related. This relationship is supported by apomorphies throughout the skeleton, including endocranial character states such as a well‐developed floccular fossa and a tall anterior semicircular canal. Our knowledge of lagerpetid anatomy has been improved by

Discussão sobre a dieta alimentar dos rincossauros (Diapsida, Archosauromorpha) do Neotriássico com base em evidências morfológicas, biomecânicas e botânicas [PDF]
, 2021 Os rincossauros do Neotriássico (Hyperodapedontidae) apresentam uma característica anatômica única no reino animal: as extremidades do dentário e das pré-maxilas encontram-se externas à boca, em um arranjo funcionalmente similar ao de um bico de ave, sem

Novas informações sobre a morfologia dentária de Hyperodapedontinae (Archosauromorpha, Rhynchosauria) [PDF]
, 2021 Rhynchosauria é um grupo de Archosauromorpha basais, com registro fóssil restrito ao período Triássico. Eram formas herbívoras com um peculiar aparato mastigatório caracterizado por pré-maxilares voltados ventralmente, formando um “bico”, e um sistema de

Sobreviventes: diversificação de Archosauromorpha após a Extinção Permo-Triássica [PDF]
, 2020 : The Archosauromorpha is defined as the clade that comprises all diapsids more closely related to the lineage of birds (Ornithodira or Avemetatarsalia) and crocodylians (Pseudosuchia or Crurotarsi) than to Lepidosauria. In addition to their ‘basal’ taxa

Journal of Vertebrate PaleontologyMultiple cranial and mandibular remains of Hyperodapedon huxleyi known from the lower part of the Upper Triassic Maleri Formation were examined to reveal distinct bite marks. These were identified as punctures based on their circular or oval or elliptical outline and deep penetration into the cortical bone, and were found associated with several bone ...

First record of Triassic Rhynchosauria (Reptilia: Diapsida) from the Lower Zambezi Valley, Zimbabwe [PDF]
, 1992 True rhynchosaurids are described from Zimbabwe for the first time. The fossils occur as partially associated skeletons and scattered isolates in upward-fining, micaceous fluvial sandstones of the Pebbly Arkose Formation (late Triassic) in the Western ...

The phylogeny of basal archosaurs [PDF]
, 1994 Archosaur systematics has received much attention from the mid 1970s and several influential works on this topic have emerged. As discrepancy exists among proposed phylogenies, some of the most important of the papers in question are assessed here ...
