Pterosaur Beach (French: Plage aux Ptérosaures) is a French palaeoichnologic site bearing tracks made by dinosaurs and pterosaurs. Located on the Mas de Pégourdy in the commune of Crayssac in the department of Lot, the site is notable because it is the first place that the fossil footprints of a landing pterosaur have been discovered. The fossil footprints are approximately 140 million years old.
Description
Pterosaur Beach was, at the end of the Jurassic era, a mudflat, flooded at high tide, on a marine lagoon in a gulf that opened on the Atlantic Ocean between Bordeaux and the island of Oléron. On it, animals foraged for food. The site has hundreds of fossilized trackways.
The site was discovered in 1993. Jean-Michel Mazin, research director of the CNRS at Claude Bernard University, oversaw the research there. Forty species of ichnotaxa have been identified.
Pterosaur Beach is protected by a metallic building, in which paleontologists work in near-complete darkness, for only a raking light can expose the ground contours and sometimes reveal new tracks.
