Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution. [PDF]

J Anat
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Natural and Anthropogenic Factors Influencing Nesting Ecology of the American Crocodile in Florida, United States

Frontiers in Ecology and Evolution, 2022
Nesting ecology of American crocodiles (Crocodylus acutus) in Florida has been both positively and negatively influenced by anthropogenic and natural factors since the species was placed on the federally endangered species list in 1975.

Boon or Bane? The Significance of Scientific Knowledge and Education Consciousness for Crocodylian Conservation in Malaysia

ASM Science Journal, 2022
A fundamental scientific apprehension of the exact nature of crocodiles, combined with the awareness through education for these reptiles could provide a crucial opportunity to enhance the conservation efforts in Malaysia.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia. [PDF]

J Anat
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

A new horned crocodile from the Plio-Pleistocene hominid sites at Olduvai Gorge, Tanzania. [PDF]

PLoS ONE, 2010
BackgroundThe fossil record reveals surprising crocodile diversity in the Neogene of Africa, but relationships with their living relatives and the biogeographic origins of the modern African crocodylian fauna are poorly understood.

Differences in distress: Variance and production of American Crocodile (Crocodylus acutus) distress calls in Belize

Ecology and Evolution, 2020
Acoustic communication of American Crocodiles (Crocodylus acutus) is relatively understudied. Our overall aim was to determine the acoustic structure of wild American Crocodile distress calls, distinguish call differences among size classes (hatchling ...

Tracking crocodylia: a review of telemetry studies on movements and spatial use

Animal Biotelemetry, 2023
Crocodylians are top predators that play key ecological roles in aquatic ecosystems. As in other groups of large predators, crocodylian populations are often impacted by habitat loss, habitat degradation or direct exploitation for commercial purposes or ...

Evaluation of the use of drones to monitor a diverse crocodylian assemblage in West Africa

, 2022
International audienceContext: West African crocodylian populations are declining and in need of conservation action. Surveys and other monitoring methods are critical components of crocodile conservation programs; however, surveys are often hindered by ...

The biochronology and palaeobiogeography of Baru (Crocodylia: Mekosuchinae) based on new specimens from the Northern Territory and Queensland, Australia [PDF]

PeerJ, 2017
New records of the Oligo–Miocene mekosuchine crocodylian, Baru, from Queensland and the Northern Territory are described. Baru wickeni and Baru darrowi are accepted as valid species in the genus and their diagnoses are revised.
