715 Roland T. Bird Dinosaur Footprints in the Sands of Time Present Transport Problems The museum expedition quarried more than 40 tons of print-bearing stratum from Paluxy Creek. It shipped much of this rock to New York in numbered chunks and thousands of fragments (page 719). Work on this section of the trail was interrupted twice by 6-foot rises in the creek (page 710). 12 footprints and all intervening open space. "We'll mount it on the brontosaur base," he said, "right behind the skeleton. That way we can create the feeling of having cap tured a 'live' brontosaur." Such an exhibit promised to be the most spectacular dinosaur show ever placed before the public. Another student of dinosaur tracks asked the shrewdest question: "Were there any noticeable signs of tail drags?" I had been expecting this. There were no signs. "The mud flat over which the sauro pod walked," I explained, "was covered by enough water to float the tail." "How deep do you think the water might have been?" I wasn't sure. Judging from the great depth of the sauropod tracks, it had been low. The carnivore trail had been made at a low stage, and the spot was undoubtedly close to shore. But had the sauropod come along at the same time? I only hoped the next Glen Rose expedition might clear up the mystery.
