The French fashion house becomes the first to turn its back on exotic pelts like snake and lizard.

Researchers have sequenced the genome of the tegu, Salvator merianae: a lizard that has taken an evolutionary step toward warm-bloodedness. It is also a highly desired pet, that can often be house-trained; unfortunately, as part of the exotic pet trade, it has been released in new environments and become a threat to local species. This extremely high-quality tegu genome sequence will be of use to researchers in the fields of evolution, physiology and ecology.

During the Triassic period (252-201 million years ago) mammal-like reptiles called therapsids co-existed with ancestors to dinosaurs, crocodiles, mammals, pterosaurs, turtles, frogs, and lizards. One group of therapsids are the dicynodonts. Researchers have discovered fossils from a new genus of gigantic dicynodont. The new species is called Lisowicia bojani.
