Washington, Dec 12 (Prensa Latina) Experts believe that the meteorite that wiped out dinosaurs ended up killing more than 80 percent of lizards and snakes that inhabit the planet, according to highlights from a study published in Proceedings of the National Academy of Sciences (PNAS).

Normally it is thought that the asteroid impact mainly affected the dinosaurs, but actually it affected the entire ecosystem, killing everything. Snakes and lizards were seriously damaged, said Nicholas R. Longrich, lead author of the study.

To reach these conclusions, scientists from the universities of Yale and Harvard examined a large number of fossils of snakes and lizards collected in North America in a wide area from New Mexico in the south to Alberta and Canada in the north.

As a result, they discovered that in the last stage of dinosaurs’ existence, there were also many other reptiles, from small lizards to large snakes, and they even determined the presence of nine species of unknown animals.
