In 1933 it was put on prominent permanent display in Glen Rose, Texas, embedded in the stone base of a community bandstand on the courthouse square. The fossilized footprint, preserved in limestone, was dug up in the 1930s from the bed of the Paluxy River in north central Texas about an hour's drive southwest of Dallas. "Since we can't say with absolute certainty they were made by a specific dinosaur, footprints are considered unique fossils and given their own scientific name," Adams said. Tracks are named separately from the dinosaur thought to have made them, he explained. The track was described and named in 1935 as Eubrontes (?) glenrosensis. The dinosaur probably left the footprint as it walked the shoreline of an ancient shallow sea that once immersed Texas, Adams said. The footprint was left by a large three-toed, bipedal, meat-eating dinosaur, most likely the theropod Acrocanthosaurus. The track is a favorite from well-known fossil-rich Dinosaur Valley State Park, where the iconic footprint draws tourists, Adams said. The fossil also has cultural importance in Texas. SMU's digital model archives a fossil that is significant within the scientific world as a type specimen - one in which the original fossil description is used to identify future specimens. "Currently there is no single 3D format that is universally portable and accepted by all software manufacturers and researchers," the authors write.ĭigitype is baseline for measuring future deterioration But the paleontologists call for development of standard formats to help ensure data accessibility.
