Review of the tetrapod skull–neck boundary: implications for the evolution of the atlas–axis complex

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2435-2470, December 2025.
ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

Novel report of an osteogenic tumor in a late Jurassic Mamenchisaurid from Thailand

open access: yesJournal of Anatomy, Volume 247, Issue 3-4, Page 699-711, September/October 2025.
Here we describe a pathology in an ulna of a Late Jurassic mamenchisaurid from Thailand. We use anatomical descriptions, CT scanning, and bone histology to identify the pathology as an osteogenic tumor. Abstract Here we report on an osseous abnormality and multiple fractures in an ulna of a subadult basal Eusauropod (Mamenchisauridae) from the Late ...

How femoral morphology informs our understanding of the evolution of ornithopod locomotion and body size

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Ornithopoda is one of the three main ornithischian dinosaur clades in which secondary quadrupedality is represented. However, when it evolved from obligate bipedality remains controversial. Indeed, the ability to alternate between the two habits was inferred in some ornithopods based on ichnological observations and a mosaic of bipedal and ...
