A suture in time: The ontogeny of cranial suture morphology in mammals

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 501-516, March 2026.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

The histology of rhynchosaur (Diapsida, Archosauromorpha) ankylothecodonty

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 526-540, March 2026.
Dental evolution is a major topic in vertebrate palaeontology and provides key insights into the evolutionary history of several amniote clades. This study investigates rhynchosaur ankylothecodonty within the broader evolutionary context of Archosauromorpha.

New information on Late Triassic sauropodomorph dinosaurs provides support for the independent acquisition of postcranial skeletal pneumaticity in avemetatarsalian lineages

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 541-578, March 2026.
PSP in early‐branching sauropodomorphs probably evolved first in the neural arches of the posterior cervical vertebrae, expanding anteriorly and posteriorly along the vertebral column. The distribution of PSP in Late Triassic early‐branching sauropodomorphs does not appear to be correlated with body size.
