March 6 (UPI) -- The ability to detach a limb is an escape strategy deployed by a number of modern species, but new research suggests the reptile Captorhinus was the first to use the trick.
The small, lizard-like reptiles were ubiquitous during the Earlier Permian period, some 289 million years ago. New analysis of Captorhinus suggests the reptile's evolutionary success could be at least partially explained by its ability to detach its tail to escape the jaws of ancient carnivorous amphibians.
