New research has uncovered a species of hook-toothed lizard that lived about 167 million years ago and has a confusing set of features seen in snakes and geckos—two very distant relatives. One of the oldest relatively complete fossil lizards yet discovered, the Jurassic specimen is described in a study, published in the journal Nature, from a multinational collaboration between the American Museum of Natural History and scientists in the United Kingdom, including University College London and the National Museums Scotland, France, and South Africa.
