A sulcimentisaurian member of the possibly paraphyletic family Silesauridae. The type species is G. paraisensis. Announced in 2024; the final article version was published in 2025.
Garcia & Müller (2025) revise the fossil record of probable pterosaur precursors from the Triassic strata of the Candelária Sequence of the Santa Maria Supersequence (Brazil) and study their phylogenetic affinities, recovering lagerpetids as an evolutionary grade ancestral to pterosaurs.[404]
Aureliano et al. (2025) compare the vertebra of the lagerpetid Venetoraptor gassenae and the pterosaur Caiuajara sp., and report evidence indicating that early signs of postcranial skeletal pneumaticity were already present in non-pterosaurian pterosauromorphs, and evidence of an increase of pneumatic complexity during pterosauromorph evolution.[405]
Tolchard, Perkins & Nesbitt (2025) describe new silesaurid fossil material from the base of the Dockum Group (Texas), providing evidence of continued presence of members of this group in the area of southwestern United States throughout the Late Triassic.[406]
Marsh (2025) identifies fossil material of a large silesaurid from the Petrified Forest Member of the Chinle Formation (Arizona, United States), and interpret both this specimen and a large coelophysoid theropod from the same locality as evidence of presence of large theropods and non-dinosaurian dinosauriforms in western North America before the Triassic–Jurassic extinction event.[407]
Lovegrove et al. (2025) describe a large silesaur femur from the Ladinian-Carnian Ntawere Formation (Zambia), and argue that the studied specimen and previously described silesaur femora from the same formation cannot be confidently referred to Lutungutali sitwensis.[408]
Evidence from the study of bone pneumaticity in extant birds, indicating that studies of skeletal pneumaticity in extinct archosaurs that don't take soft tissues in the internal bone cavities into account might overestimate the volume fraction of pneumatic bones that was composed of air, is presented by Burton et al. (2025).[410]
Byrne et al. (2025) reconstruct the red blood cell size evolution in archosaurs on the basis of histological indicators of red blood cell size, and report evidence of increase of their size in crocodile-line archosaurs and decrease of their size in bird-line archosaurs.[411]
Xu & Barrett (2025) review the research on the evolutionary history of feathers from the preceding years.[412]
New tetrapod fossil assemblage, including lagerpetid and early-diverging sauropodomorph fossil material, is described from the Carnian strata from the lower exposures of the Niemeyer Complex (Brazil) by Doering et al. (2025).[413]
A study on the biogeography of Triassic pterosaurs and lagerpetids is published by Foffa et al. (2025), who interpret their findings as indicating that lagerpetids tolerated a broader range of environmental conditions than pterosaurs, resulting in expansion of pterosaur distribution only after the climate became more humid following the Carnian pluvial episode.[414]
Sena et al. (2025) measure metadiaphyseal and nutrient foramina openings in the femora of immature specimens of Halszkaraptor and Rhamphorhynchus, and calculate similar mass-independent maximal metabolic rates and blood flow rates for the studied archosaurs in spite of their different locomotion and ecology.[415]
Wang et al. (2025) describe new feather specimens from the Cretaceous amber from Myanmar, including a feather type with similarities to primitive feathers of non-avian theropods, preserved with melanosomes suggestive of a black color with a red luster, and a probable ornithothoracine (possibly enantiornithean) feather type preserved with melanosomes suggestive of a gray or black color.[416]
Hedge et al. (2025) revise archosaur eggshells from the Mussentuchit Member of the Cedar Mountain Formation (Utah, United States), and identify remains of eggs produced by oviraptorosaur theropods, ornithopods and a crocodylomorph.[417]
