Veterinary Record, EarlyView.Abstract Background Gastrolith ingestion is a known inherent behaviour in crocodiles. However, the interpretation of coelomic radiographs in crocodilians is challenging due to the limited informative literature in this field. Methods Dorsoventral coelomic radiographs of 49 juvenile saltwater crocodiles (Crocodylus porosus) were acquired twice, with an ...

Thermoregulation in captive broad-snouted caiman (Caiman latirostris) [PDF]
, 2014 Background: Crocodilians are ectothermic animals. For this reason, the environmental temperature has substantial effects on their physiology and behavior.

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts
Conservation Science and Practice, EarlyView.Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

Live birth in an archosauromorph reptile
Nature Communications, 2017 Although live birth evolved repeatedly in other clades, it has not been found in archosauromorphs, the group including modern birds and crocodilians. Here, the authors describe a fossilized pregnantDinocephalosaurusfrom ∼245 million years ago, providing ...

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

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

The wide gape of snakes: A comparison of the developing mandibular symphysis in sauropsids
Journal of Anatomy, EarlyView.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 ...
