Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1451-1463, June 2026.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Stable oxygen isotopes of crocodilian tooth enamel allow tracking Plio-Pleistocene evolution of freshwater environments and climate in the Shungura Formation (Turkana Depression, Ethiopia) [PDF]

open access: yesBiogeosciences
This study adopts a new approach describing palaeohydrology and palaeoclimates based on the interpretation of stable oxygen isotopes (δ18Op) recorded in fossil crocodilian teeth.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

open access: yesDevelopmental Dynamics, Volume 255, Issue 6, Page 602-615, June 2026.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Retention of the Full Visual Opsin Repertoire in Some Australian Cryptozoic Lizards

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
This study investigates the link between visual evolution and fossorial habits in the endemic Australian skink genus Lerista. We provide evidence for positive site‐specific selection in all 4 cone opsins, as well as relaxed selection specific to LWS. We also provide evidence of selection linked to limb reduction, an indicator of fossorial adaptation ...

The wide gape of snakes: A comparison of the developing mandibular symphysis in sauropsids

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 937-949, June 2026.
Our analysis explores the adaptations at the mandibular symphysis required to allow extreme lower jaw mobility in macrostomate snakes taking a comparative approach. Abstract The origin and evolution of snakes has been marked by the acquisition of many morphological and functional novelties, one of which is the possession of a highly kinetic skull ...

Radiographic-anatomical aspects and gastrointestinal transit time in the spectacled caiman Caiman crocodilus crocodilus (Linnaeus, 1758) (Crocodylia, Alligatoridae)

open access: yesBiotemas, 2014
In Brazil, there is increasing interest in the establishment of captive breeding programs for caiman. However, there is a paucity of in-depth studies on the proper care of these reptiles in captivity, particularly regarding optimal food type and ...
