An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, Volume 309, Issue 11, Page 3137-3168, November 2026.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

Journal of Anatomy, Volume 249, Issue 4, Page 924-949, October 2026.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Odontoid fractures

MOJ Orthopedics & Rheumatology, 2018
Odontoid fractures account for approximately 7-15% (1) of cervical spine fractures, and almost 60% of fractures involving the axis. Neurological involvement is seen in upto 25% pts (2), and the primary mortality rate is around 12% (2). The mean age of occurrence is 47 years, with 2 peaks.
