Morphology And Physiology Of The Crocodylia [PDF]

, 1993
This chapter provides an overview of the external characteristics of Crocodylia, their musculoskeletal system, locomotion, buoyancy, feeding and digestion. More details are provided of their thermal relations, their respiratory and cardiovascular physiology and oxygen transport, including its ontogeny.

First occurrences of neural canal ridges in Crocodylia

Acta Palaeontologica Polonica
Crocodylia is a crown group inclusive of the last common ancestor of extant crocodylians, followed by successive extinct and extant taxa forming Alligatoroidea, Crocodyloidea, and Gavialoidea.

ReptTraits: a comprehensive dataset of ecological traits in reptiles [PDF]

Scientific Data
Trait datasets are increasingly being used in studies investigating eco-evolutionary theory and global conservation initiatives. Reptiles are emerging as a key group for studying these questions because their traits are crucial for understanding the ...

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

‘Ear stones’ in crocodylians: a cross-species comparative and ontogenetic survey of otolith structures

Royal Society Open Science, 2022
The vestibular system of the inner ear is a crucial sensory organ, involved in the sensation of balance and equilibrium. It consists of three semicircular canals that sense angular rotations of the head and the vestibule that detects linear acceleration ...

Controlled feeding experiments with juvenile alligators reveal microscopic dental wear texture patterns associated with hard-object feeding

Frontiers in Ecology and Evolution, 2022
Dental wear analyses are classically applied to mammals because they have evolved heterodont dentitions for sophisticated mastication. Recently, several studies have shown a correlation between pre-assigned and analytically inferred diet preferences in ...

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 ...
