A DIAGNOSIS OF ALLIGATOR MISSISSIPPIENSIS BITE MARKS WITH COMPARISONS TO EXISTING CROCODYLIAN DATASETS

, 2018
Crocodylians are known to consume and modify bones, but actualistic observations of their bite marks have been limited to forensic case studies and surveys of two taxa: Crocodylus niloticus and Crocodylus porosus.

Climatic Niche Modelling Reveals Limited Phylogenetic Niche Conservatism in New World Crocodylians

Journal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim Phylogenetic niche conservatism, the tendency of closely related species to retain ancestral ecological traits, has gained considerable interest, yet the lack of integration across independent evaluation methods has hindered our understanding of whether niches are conserved or dynamic.

Traces of a large crocodylian from the Lower Cretaceous Sousa Formation, Brazil.

, 2010
Body imprints and tracks attributed to large crocodylians from the Lower Cretaceous Sousa Formation of Brazil are described and interpreted as having been produced in a subaqueous environment.

The crook in the caudals: Kinematics of defensive tail swipes in the American alligator (Alligator mississippiensis).

Vertebrate Anatomy, Morphology, Palaeontology
The American alligator responds to physical threats with a defensive tail swipe, a lateral and vertical sweep of the tail. Despite the large size of the alligator tail, it accounts for roughly half the length and a quarter of the mass of the entire ...

Coordinate data of crocodylian crania (pre-superimposed)

, 2014
Coordinate data of 78 three-dimensional landmarks from 204 cranial specimens of 10 extant crocodylian species. All specimens, with the exception of Gavialis and Tomistoma, are from non-captive individuals.

Ancestral Hybridization Yields Evolutionary Distinct Hybrids Lineages and Species Boundaries in Crocodiles, Posing Unique Conservation Conundrums

Frontiers in Ecology and Evolution, 2018
Interspecific hybridization can lead to adaptation and speciation, especially in the context of recent radiations. The emblematic Crocodylus (true crocodiles) is the most broadly distributed, ecologically diverse, and species-rich crocodylian genus ...

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

New frontiers in imaging, anatomy and mechanics of crocodylian jaw muscles

, 2022
New imaging and biomechanical approaches have heralded a renaissance in our understanding of crocodylian anatomy. Here, we review a series of approaches in the preparation, imaging, and functional analysis of the jaw muscles of crocodylians.

The Gavialis - Tomistoma debate: the contribution of skull ontogenetic allometry and growth trajectories to the study of crocodylian relationships

, 2010
The phylogenetic placement of Tomistoma and Gavialis crocodiles depends largely upon whether molecular or morphological data are utilized. Molecular analyses consider them as sister taxa, whereas morphological/paleontological analyses set Gavialis apart ...

Neuroanatomy of the mekosuchine crocodylianTrilophosuchus rackhamiWillis, 1993

Journal of Anatomy, 2022
AbstractAlthough our knowledge on crocodylomorph palaeoneurology has experienced considerable growth in recent years, the neuroanatomy of many crocodylomorph taxa has yet to be studied. This is true for Australian taxa, where thus far only two crocodylian crocodylomorphs have had aspects of their neuroanatomy explored.
