Roland T. Bird - Dinosaur Hunter. . In 1938, Roland (R.T.) Bird traveled all over the United States in search of fossils for the American Museum of Natural History in New York. , The dinosaur tracks that he found here sent shockwaves through the scientific world. There were hundreds of massive, saucer-shaped sauropod tracks - the first ever identified, together with numerous three-toed theropod tracks buried just beneath the Paluxy River. Based on this find, R.T. Bird developed the theory that sauropods walked on land., A Painstaking Job , It took R.T. Bird and his crew two years to excavate these ancient dinosaur tracks. Using sandbags to hold back the river, he chiseled the trackways out of the bedrock, broke them into pieces, carefully cataloged each one, and then wrapped them in plaster-coated burlap for safe transport to New York., Captions , Lower Left: R.T.
