University of Arkansas Researchers have found a large field of dinosaur tracks that are about 120 million years old. The fossilized tracks are somewhere in southwestern Arkansas and are from several dinosaur species. The site is on private property and the university has not divulged its exact location. The university says the tracks cover about two football fields and are from the early Cretaceous period. Researchers say some of the tracks appear to be from large carnivores and large plant eaters. Scientists are still working to identify all of the various prints.
In 1983, a large number of dinosaur tracks were found at a gypsum mine near Nashville in southwestern Arkansas. The prints were photographed and molds were taken before the mining activity destroyed them.
