165-Million-Year-Old Spider Fossil Preserves Original Features

Friday, May 6, 2011

New fossils from the Middle Jurassic period show what at least one species of spider, Eoplectreurys gertschi, looked like when dinosaurs dominated the planet.

Check out the incredible detail on this fossil. Credit for all images goes to Paul Selden of the University of Kansas.

The findings, published in the journal Naturwissenschaften, extend the fossil record for this particular family of spiders by at least 120 million years, and suggest that these spiders plummeted in numbers, losing much of their original range.

Selden and co-author Diying Huang write, "This small family is restricted to southwestern USA, Mexico and the adjacent Caribbean area today." The fossils, however, were excavated at Inner Mongolia, China.
