Scientists have discovered the first dinosaur tracks on the Arabian Peninsula. In the May 21 issue of the journal PLoS ONE, they report evidence of a large ornithopod dinosaur, as well as a herd of 11 sauropods walking along a Mesozoic coastal mudflat in what is now the Republic of Yemen. “No dinosaur trackways had been found in this area previously. It’s really a blank spot on the map,†said Anne Schulp of the Maastricht Museum of Natural History in The Netherlands. He conducted the study with Ohio University paleontologist Nancy Stevens and Mohammed Al-Wosabi of Sana’a University in Yemen.
The finding also is an excellent example of dinosaur herding behavior, the researchers report. The site preserved footprints of 11 small and large sauropods — long-necked, herbivorous dinosaurs that lived in the Jurassic and Cretaceous periods — traveling together at the same speed.
