During the late 1930s, Roland T. Bird collected for the American Museum of Natural History, New York City, a number of Early Cretaceous dinosaur fossil footprints at the Paluxy River, near Glen Rose, Texas. These specimens included a trackway recording the pursuit of a sauropod dinosaur by a theropod. Shown here are two souvenir postcards from the American Museum, both dated 1939, the one above showing local boy Tommy Pendly inside one of the water-filled sauropod tracks; the other, locals selling dinosaur footprints as rock garden ornaments. The Tyrannosaurus statue was built by the Jonas Studios for the 1964 New York World’s Fair.
