Determining whether a phosphatic concretion containing a Cretaceous juvenile crocodylian is a coprolite or a non-fecal concretion [PDF]
Scientific ReportsPhosphatic concretions in terrestrial settings are often identified as coprolites based upon their biotic contents and high phosphorus levels. However, recent discoveries have shown that non-fecal origins of fossiliferous phosphatic concretions are more ...

Expanded phylogeny elucidates Deinosuchus relationships, crocodylian osmoregulation and body-size evolution [PDF]
Communications BiologyTransmarine distribution and gigantism in the Late Cretaceous North American crocodyliform Deinosuchus has been difficult to reconcile with consistently inferred phylogenetic relationships to alligatorids, an otherwise freshwater and smaller-bodied group.

The velar chord and dynamic integration of the gular valve in crocodylians. [PDF]
Anat Rec (Hoboken)AbstractCrocodylians evolved a unique gular valve that is capable of creating a water‐tight seal between the oral and pharyngeal cavities, allowing the animal to safely submerge with an open mouth. The gular valve has traditionally been described as consisting of two separate parts: an active mobile ventral portion (consisting of the tongue and ...

Unraveling Population Trend of a Critically Endangered Freshwater Crocodylian, Gharial (Gavialis gangeticus) in the National Chambal Sanctuary, India [PDF]
Ecology and EvolutionThe gharial (Gavialis gangeticus), an endemic freshwater crocodylian species, has shown signs of recovery following a severe population decline, primarily due to concerted conservation efforts initiated in the mid‐1970s.

Population status and genetic assessment of mugger (Crocodylus palustris) in a tropical regulated river system in North India [PDF]
Scientific ReportsFor rewilding the depleted crocodylian populations in India, a targeted ‘one-species one area’ based conservation approach was adopted in the early-1970s.

Developmental and evolutionary origins of the crocodylian snout and amniote face
, 2021 Crocodylians (alligators, crocodiles, and gharial) are instantly recognizable by their flattened skulls and tooth-filled jaws, adaptations which aid in capturing prey in shallow water and along riverbanks.

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 ...
