New research published in eLife by researchers from the Institut Català de Paleontologia Miquel Crusafont (ICP) and the University of Bristol (UB) moves back the moment of the radiation of squamates ―the group of reptiles that includes lizards, snakes and worm lizards― to the Jurassic, a long time before current estimates. The Squamata is the largest order of reptiles, including lizards, snakes and worm lizards. Squamates are all cold-blooded, and their skins are covered by horny scales. They are key parts of modern terrestrial faunas, especially in warmer climates, with an astonishing diversity of more than 10,000 species. However, understanding the evolutionary paths that forged their success are still poorly understood. There is consensus that all the main squamate groups had...

About a fifth of reptile species - from the Galapagos tortoises to the Komodo dragon of the Indonesian islands, from West Africa's rhinoceros viper to India's gharial - are threatened with extinction, researchers said on Wednesday in the first comprehensive global status assessment for reptiles. The study examined 10,196 reptile species including turtles, crocodilians, lizards, snakes and the tuatara, the only surviving member of a lineage dating back more than 200 million years. They found that 21% of species are critically endangered, endangered or vulnerable to extinction as defined by the International Union for Conservation of Nature (IUCN), the global authority on the status of species. They also identified 31 species that already have gone extinct. FILE PHOTO: A reptile curat...
