Quantitative heterodonty in Crocodylia: assessing size and shape across modern and extinct taxa [PDF]
PeerJ, 2019 Heterodonty in Crocodylia and closely related taxa has not been defined quantitatively, as the teeth rarely have been measured. This has resulted in a range of qualitative descriptors, with little consensus on the condition of dental morphology in the ...

Climate constrains the evolutionary history and biodiversity of crocodylians [PDF]
Nature Communications, 2015 AbstractThe fossil record of crocodylians and their relatives (pseudosuchians) reveals a rich evolutionary history, prompting questions about causes of long-term decline to their present-day low biodiversity. We analyse climatic drivers of subsampled pseudosuchian biodiversity over their 250 million year history, using a comprehensive new data set ...

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 ...
