No teeth cleaning needed: Crocodiles shed old teeth, grow new ones
Having one of the most powerful bites in the animal kingdom, crocodiles must be able to bite hard to eat their food such as turtles, wildebeest and other large prey. Now, researchers at the University of Missouri have found that crocodiles -- and even their plant-eating ancestors -- had thin tooth enamel, a trait that is in stark contrast to humans and other hard-biting species. These findings could suggest new approaches for dealing with people's teeth. (2019-08-13)

New measurement of crocodilian nerves could help scientists understand ancient animals
A new study from the University of Missouri has measured the nerves responsible for the super-sensitive skin on a crocodile's face, which will help biologists understand how today's animals, as well as dinosaurs and crocodiles that lived millions of years ago, interact with the environment around them. (2013-04-04)

Crocodiles ride ocean currents for ocean travel
The mystery of how the world's largest living reptile -- the estuarine crocodile -- has come to occupy so many South Pacific islands separated by huge stretches of ocean despite being a poor swimmer has at last been solved by a group of Australian ecologists. Publishing their new study in the British Ecological Society's Journal of Animal Ecology, they say that like a surfer catching a wave, the crocodiles ride ocean currents to cross large areas of open sea. (2010-06-07)

Ancient crocodiles walked on two legs like dinosaurs
An international research team has been stunned to discover that some species of ancient crocodiles walked on their two hind legs like dinosaurs and measured over three metres in length. University of Queensland palaeontologist Dr Anthony Romilio said the researchers first thought the similar-shaped fossilised footprints were from another ancient animal known as the pterosaurs. (2020-06-11)

University of Tennessee study: Crocodiles just wanna have fun, too
The research shows that crocodilians engage in all three main types of play distinguished by behavior specialists: locomotor play, play with objects and social play. Crocodiles have also been seen playing with other animals. In rare cases, individual crocodilians have been known to bond so strongly with people that they become playmates for years. (2015-02-10)

To study the diet of ancient crocodiles, two researchers--one from the University of Tennessee, Knoxville, and one from Stony Brook University--combined mathematical analyses of the animals' shapes, surveys of modern crocodiles' diet, modeling methods for reconstructing the diet of fossil groups, and forensic-style interpretations of damaged bones from the distant past. (2019-09-30)

14 closely related crocodiles existed around 5 million years ago
14 species of crocodile lived in South America around 5 million years ago, at least seven of which populated the coastal areas of the Urumaco River in Venezuela at the same time. Paleontologists from the University of Zurich have found evidence of an abundance of closely related crocodiles that remains unparalleled to this day. As they were highly specialized, the crocodiles occupied different eco-niches. When the watercourses changed due to the Andean uplift, however, all the crocodile species became extinct. (2013-05-21)

Crocodile face off
Despite often being portrayed as creatures that have remained virtually unchanged for millions of years, a new Harvard study shows crocodiles have repeatedly altered their developmental patterns, leading to much of the diversity found in modern, living crocodiles. (2019-02-20)

Discovery places turtles next to lizards on family tree
For decades, paleontologists and molecular biologists have disagreed about whether turtles are more closely related to birds and crocodiles or to lizards. Now, two scientists from the Mount Desert Island Biological Laboratory in Bar Harbor, Maine, and their colleagues from Dartmouth College and Harvard and Yale Universities have developed a new technique using microRNAs for classifying animals, and the secret is out. Turtles are closer kin to lizards than crocodiles. (2011-07-25)
