A University of Cambridge-led team has analyzed giant anaconda fossils from South America to deduce that these tropical snakes reached their maximum size 12.4 million years ago and have remained giants ever since. Leer más.

A tiny 242-million-year-old fossil from Devon is shaking up scientists’ assumptions about the earliest members of the lizard lineage. Instead of the expected skull hinges and palate teeth typical of modern lizards and snakes, this ancient creature shows a surprising mix of primitive and unusual traits—along with strikingly large, blade-like teeth.

A newly identified crocodile relative from Egypt pushes back the origins of the marine-hunting dyrosaurids by millions of years. The fossil, Wadisuchus kassabi, shows a mix of primitive and advanced traits that mark a key evolutionary transition. Leer más.

The size of reptile home ranges can vary drastically depending on the population density, habitat characteristics, availability of food and many other factors (Day, 2012; O’Donnell and delBarco-Trillo, 2020). Leer más
Like in Anolis lizards, the evolution of adhesive toepads in geckos is often seen as a key innovation, allowing these lizards to exploit vertical environments. Gecko toepads are among the most advanced in the animal kingdom – inspiring research in biomimetics and synthetic adhesion for years. Leer más.
