Wildlife Monographs, Volume 223, Issue 1, August 2026.We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

A well-preserved vertebra provides new insights into rebbachisaurid sauropod caudal anatomical and pneumatic features [PDF]
Acta Palaeontologica PolonicaRebbachisauridae is a clade of sauropod dinosaurs whose maximum diversification and abundance are known from the Cretaceous of South America. We describe an anterior caudal vertebra, MDPA-Pv 007, from the Upper Cretaceous of Argentine Patagonia, whose ...

The Anatomical Record, Volume 309, Issue 7, Page 1713-1748, July 2026.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

A re-examination of a Middle Jurassic sauropod limb bone from the Bathonian of the Isle of Skye [PDF]
, 2004 A limb bone from the Bathonian of the Isle of Skye, previously identified as a possible femur of the sauropod dinosaur <i>Cetiosaurus</i>, is reassessed in light of comparisons with other sauropod material, including the lectotype of <i>

A re-evaluation of the enigmatic dinosauriform Caseosaurus crosbyensis from the Late Triassic of Texas, USA and its implications for early dinosaur evolution [PDF]
Acta Palaeontologica Polonica, 2018 The holotype specimen of the Late Triassic dinosauriform Caseosaurus crosbyensis is redescribed and evaluated phylogenetically for the first time, providing new anatomical information and data on the earliest dinosaurs and their evolution within the ...

, 1992 Dinosaurs The dinosaur faunas of the Fruitland and Kirtland Formations were first described in detail by Gilmore (1916), who based his study on specimens collected by Bauer and Reeside. Subsequently, the collections of Charles Sternberg were described by Wiman(1930, 1931, 1932, 1933), Osborn (1923), Gilmore (1935) and Ostrom (1960, 1961).

Journal of Comparative Neurology, Volume 534, Issue 7, July 2026.The phylogenetic position of oviraptorosaurs close to birds makes them a key group for understanding the acquisition of avian senses. Here, we describe the first inner ear endocasts for caenagnathids, a major subclade of oviraptorosaurs, which demonstrates that labyrinth morphology varied more than expected within oviraptorosaurs.

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail
Small, Volume 22, Issue 40, 17 July 2026.The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Anatomical network analysis of sauropodomorph cranial topology
Palaeontology, Volume 69, Issue 4, July/August 2026.Abstract The cranium of sauropodomorph dinosaurs is relatively small and diverse in shape. However, the cranial topology of sauropodomorphs has not previously been investigated. The distinct pattern of physical interactions (joints) among the elements (bones) of an anatomical system (cranium) reveals information about its morphology, leading to a ...

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology
Biological Reviews, Volume 101, Issue 3, Page 1073-1090, June 2026.ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.
