🚨Research alert! A recent study led by Museum Macaulay Curator Roger Benson details a new species of Jurassic reptile that has links to the origins of lizards and snakes.
With python-like hooked teeth and a body similar to a gecko’s, the newly described species, named Breugnathair elgolensis, lived about 167 million years ago and is one of the oldest relatively complete fossil lizards yet discovered. Nearly 16 in (40.6 cm) long from head to tail, Breugnathair was one of the largest lizards in its ecosystem, where it likely preyed on smaller lizards, early mammals, and other vertebrates, like young dinosaurs.
But is it a lizard-like ancestor of snakes or a predecessor of all lizards and snakes? Because it has such an unusual mixture of features, and because other fossils that shed light on early squamate evolution are rare, the researchers did not arrive at a conclusive answer. “This fossil gets us quite far, but it doesn’t get us all of the way,” Benson said. “However, it makes us even more excited about the possibility of figuring out where snakes come from.”
