Abstract:
The clade Archosauria contains two very different sister groups in terms of diversity (number of species) and disparity (phenotypic variation): Crurotarsi (taxa more closely related to crocodiles than to birds) and Ornithodira (pterosaurs and dinosaurs including birds). The extant species of Crurotarsi may constitute a biased sample of past biodiversity regarding growth patterns and metabolic rates. Bone histological characters can be conserved over hundreds of millions of years in the fossil record and potentially contain information about individual age at death, age at sexual maturity, bone

Abstract:
The phylogenetic position of Scleromochlus taylori has been disputed recently, in terms of whether it is a basal sister group of Pterosauria or of Dinosauromorpha. The seven specimens, all from the Lossiemouth Sandstone Formation (late Carnian, Late Triassic) of Lossiemouth, near Elgin, north–east Scotland, suggest that Scleromochlus shares no unique features with either Pterosauria or Dinosauromorpha, together the Ornithodira, but is a close outgroup. Scleromochlus retains a primitive ankle structure, and it has a slender humerus, femur and fibula. Scleromochlus shows the classic bird–like ch

Archosauromorpha é definido como o clado que compreende todos os diápsidos mais intimamente relacionados à linhagem de aves (Ornithodira ou Avemetatarsalia) e crocodilianos (Pseudosuchia ou Crurotarsi) do que aos lepidossauros. Além de seus táxons basais (e.g., Tanystropheidae, Rhynchosauria e Allokotosauria), Archosauromorpha inclui o clado Archosauriformes, que, por sua vez, inclui os Archosauria. Durante o Triássico, os arcossauromorfos tornaram-se um dos primeiros grupos de diápsidos a se diversificar em termos de tamanho corporal e disparidade morfológica. A extinção em massa Permo-triáss

Abstract:
Sikannisuchus huskyi, a new genus and species of archosaur, is described from the Upper Triassic (Norian) Pardonet Formation of northeastern British Columbia. It has a broad, flat skull, and may have reached 4 m in length. It is referred to the Archosauria on the basis of a lateral mandibular fenestra, laterally compressed serrated teeth, elongate transverse processes, neural spine table, osteoderms, and thecodont dentition. It is autapomorphic in that the postfrontal enters the border of both the orbit and the supratemporal fenestra, and it has a large prefrontal that contacts both the nasal

Abstract:
This study aims to investigate functional disparity in the locomotor apparatus of bipedal archosaurs. We use reconstructions of hindlimb myology of extant and extinct archosaurs to generate musculoskeletal biomechanical models to test hypothesized convergence between bipedal crocodile-line archosaurs and dinosaurs. Quantitative comparison of muscle leverage supports the inference that bipedal crocodile-line archosaurs and non-avian theropods had highly convergent hindlimb myology, suggesting similar muscular mechanics and neuromuscular control of locomotion.

Um esqueleto parcialmente completo e semi-articulado de um rauissuquídeo, proveniente de níveis pertencentes à Cenozona de Therapsida (Mesotriássico) da Formação Santa Maria, foi coletado em 2003, no município de Dona Francisca, RS, Brasil. Neste espécime, os ossos do crânio e mandíbula estavam quase todos desarticulados e puderam ser retirados isoladamente da rocha. Tal forma de preservação possivelmente seria uma evidência de que os ossos do crânio deste animal poderiam apresentar mobilidades entre si.
