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

open access: yesJ 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

Taxonomic clarifications concerning the crocodyliform genus Isisfordia [PDF]

open access: yesPeerJ, 2020
Background In a recent paper, a new species of the crocodyliform genus Isisfordia was erected based on, in part, a specimen previously designated as the holotype of ‘Crocodylus (Bottosaurus)’ selaslophensis. This new species was given the name Isisfordia

Role of Chromosome Changes in Evolution and Diversity [PDF]

open access: yesGenomics & Informatics, 2015
The karyotypes of most species of crocodilians were studied using conventional and molecular cytogenetics. These provided an important contribution of chromosomal rearrangements for the evolutionary processes of Crocodylia and Sauropsida (birds and ...

The late Pleistocene horned crocodile Voay robustus (Grandidier & Vaillant, 1872) from Madagascar in the Museum für Naturkunde Berlin [PDF]

open access: yesFossil Record, 2009
Crocodylian material from late Pleistocene localities around Antsirabe, Madagascar, stored in the collection of the Museum für Naturkunde, Berlin, was surveyed. Several skeletal elements, including skull bones, vertebrae, ribs, osteoderms, and limb bones

Trace element concentrations in caudal scutes from Crocodylus moreletii and Crocodylus acutus in Belize in relation to biological variables and land use

open access: yesEcotoxicology and Environmental Safety, 2022
Crocodylus moreletii (Morelet’s crocodile) and Crocodylus acutus (American crocodile) are generalist, apex predators of subtropical aquatic habitats in Central America.

Morphological and functional changes in the vertebral column with increasing aquatic adaptation in crocodylomorphs [PDF]

open access: yesRoyal Society Open Science, 2015
The lineage leading to modern Crocodylia has undergone dramatic evolutionary changes in morphology, ecology and locomotion over the past 200+ Myr. These functional innovations may be explained in part by morphological changes in the axial skeleton, which

Cave-dwelling crocodiles of Central Belize

open access: yesInternational Journal of Speleology, 2023
We provide the results on the first systematic effort to study cave-dwelling crocodiles in central Belize. For nearly three decades, managers at Runaway Creek Nature Reserve have frequently observed crocodile tracks and trackways in caves, while ...

The stuffed crocodile of “Castel Nuovo” in Naples (Italy): new insights from ancient DNA and radiocarbon

open access: yesThe European Zoological Journal, 2020
In the present study, a stuffed crocodile displayed for centuries at the “Castel Nuovo” (New Castle) in Naples was radiocarbon dated and examined using ancient DNA analysis. The specimen was classified as Crocodylus niloticus based on its large body size

Integrating molecular, phenotypic and environmental data to elucidate patterns of crocodile hybridization in Belize [PDF]

open access: yesRoyal Society Open Science, 2015
The genus Crocodylus comprises 12 currently recognized species, many of which can be difficult to differentiate phenotypically. Interspecific hybridization among crocodiles is known to occur in captivity and has been documented between some species in ...

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.
