There’s nothing quite like seeing firsthand dinosaur tracks that were made in mud or wet sand long ago. But how long ago were they made, and how did they form? No process quite like that happens today. We recently photographed similar tracks made in similar sediments from sites in the American South and West. What links them together? Did these dinosaur tracks really form according to the evolution-based story printed on the state-sponsored placards we saw at some of the sites? First some facts, then some answers.
Tracks near San Antonio, Texas
At Government Canyon State Natural Area, large three-toed theropod tracks are embedded in limestone and match the clawed feet of a 38-foot-long Acrocanthosaurus—a T. rex look-alike with a small head crest. The limestone layer directly above it contains sauropod tracks assigned to a teenage Sauroposeidon, a long-neck dinosaur about 55 feet long. Scientists use the size and spacing of the footprints to estimate animal sizes. These sets of tracks occur near the top of the Glen Rose Limestone, close to the southernmost exposures of this particular limestone bed.
