Roars, Rumbles, and Resonance: A Systematic Review and Meta‐Analysis of Crocodylian Acoustic Signals [PDF]

open access: yesEcology and Evolution
Crocodylians are highly vocal reptiles, possessing a complex acoustic signalling system including vocal and non‐vocal signals used for courtship, mating, mediating conflict, and providing maternal care.

First record of a tomistomine crocodylian from Australia [PDF]

open access: yesScientific Reports, 2021
Based on the known fossil record, the majority of crocodylians from the Cenozoic Era of Australia are referred to the extinct clade Mekosuchinae. The only extant crocodylians in Australia are two species of Crocodylus.

Ontogenetic variation in the crocodylian vestibular system [PDF]

open access: yesJournal of Anatomy, 2021
Crocodylians today live in tropical to subtropical environments, occupying mostly shallow waters. Their body size changes drastically during ontogeny, as do their skull dimensions and bite forces, which are associated with changes in prey preferences ...

A juvenile subfossil crocodylian from Anjohibe Cave, Northwestern Madagascar [PDF]

open access: yesPeerJ, 2016
Madagascar’s subfossil record preserves a diverse community of animals including elephant birds, pygmy hippopotamus, giant lemurs, turtles, crocodiles, bats, rodents, and carnivorans.

Using Crocodylians for monitoring mercury in the tropics. [PDF]

open access: yesEcotoxicology, 2023
AbstractMercury contamination is a widespread phenomenon that impacts ecosystems worldwide. Artisanal Small Scale Gold Mining (ASGM) activities are responsible for more than a third of atmospheric Hg emission. Due to Hg toxicity and its broad and elevated prevalence in the environment resulting from ASGM activities in the tropics, its biomonitoring is ...

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha [PDF]

open access: yesJournal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Unique Population or Unique Species? Genetic Insights Into the Pygmy Freshwater Crocodiles of Northern Australia [PDF]

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
There is debate over whether isolated populations of “pygmy” Australian freshwater crocodiles are a unique species. This is a conservation concern as these populations face unique challenges. We found some population differences which support these populations as being ecologically unique and valuable for targeted conservation.

Crocodylian remains from the Miocene of the Fore-Carpathian Basin and its foreland—including the world’s northernmost Neogene crocodylian

open access: yesActa Palaeontologica Polonica
The geographic distribution of Crocodylia in Europe throughout the Cenozoic experienced fluctuations in the extension of its northern limit. Whereas crocodylians reached very high latitudes during the early Eocene (78ºN), their northward extension was ...

Novel Alligator Cathelicidin As-CATH8 Demonstrates Anti-Infective Activity against Clinically Relevant and Crocodylian Bacterial Pathogens [PDF]

open access: yesAntibiotics, 2022
Host defense peptides (HDPs) represent an alternative way to address the emergence of antibiotic resistance. Crocodylians are interesting species for the study of these molecules because of their potent immune system, which confers high resistance to ...

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae [PDF]

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 787-802, October 2026.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...
