Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

Development of the abdominal musculature in the chicken embryo

open access: yesJournal of Anatomy, EarlyView.
In this study, we investigate anatomy, morphogenesis, segmental origin, and fiber formation of the abdominal musculature in the chicken embryo. We show that abdominal muscles arise from somites 24 to 28, and that the segmental identity of individual fibers in the abdominal muscle sheets is maintained.

Hoffmann's two‐toed sloth I: Complete myology in the thoracic limb of Choloepus (Pilosa: Xenarthra)

open access: yesJournal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and prolonged suspensory support than three‐toed sloths and accordingly demonstrate myological traits consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the elbow joint, and grip on the support.

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

open access: yesJournal of Anatomy, EarlyView.
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.

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

open access: yesJournal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb
