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

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

open access: yesFrontiers 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 ...

A new horned crocodile from the Plio-Pleistocene hominid sites at Olduvai Gorge, Tanzania. [PDF]

open access: yesPLoS ONE, 2010
BackgroundThe fossil record reveals surprising crocodile diversity in the Neogene of Africa, but relationships with their living relatives and the biogeographic origins of the modern African crocodylian fauna are poorly understood.

Genetic evidence supports a distinct lineage of American crocodile (Crocodylus acutus) in the Greater Antilles [PDF]

open access: yesPeerJ, 2018
Four species of true crocodile (genus Crocodylus) have been described from the Americas. Three of these crocodile species exhibit non-overlapping distributions—Crocodylus intermedius in South America, C. moreletii along the Caribbean coast of Mesoamerica,

Appendicular Muscle Physiology and Biomechanics inCrocodylus niloticus [PDF]

open access: yesIntegrative Organismal Biology, 2020
AbstractArchosaurian reptiles (including living crocodiles and birds) had an explosive diversification of locomotor form and function since the Triassic approximately 250 million years ago. Their limb muscle physiology and biomechanics are pivotal to our understanding of how their diversity and evolution relate to locomotor function. Muscle contraction

Stomach histology of Crocodylus siamensis and Gavialis gangeticus reveals analogy of archosaur “gizzards”, with implication on crocodylian gastroliths function

open access: yesActa Herpetologica, 2020
Two groups of extant Archosauria, Crocodylia and Neornithes, have two-chambered stomachs and store gastroliths inside their “gizzards”. Morphological similarities of the “gizzards” lead some previous studies to assume that the presence of this structure,

Were human babies used as bait in crocodile hunts in colonial Sri Lanka?

open access: yesJournal of Threatened Taxa, 2015
Use of live animals as bait is not an uncommon practice in hunting worldwide.  However, some curious accounts of the use of human babies as bait to lure crocodiles in sport hunting exist on the island of Sri Lanka, where sport hunting was common during ...
