So much history has unfolded across the vast Texas landscape. In Glen Rose, the so-called Dinosaur Capital of Texas, ancient tracks have revealed incredible stories.
The swift moving waters of the Paluxy River cut right through the Dinosaur Valley State Park, where park ranger Kathy Lenz says 113-million-year-old tracks were first uncovered in 1909.
"A little boy had skipped school and came to the park to find a good fishing hole, and what he found was dinosaur tracks," Lenz explained. "We have some of the best-preserved dinosaur tracks in the world and because they were so perfectly preserved, it made us famous."
The latest news from around North Texas.
Then, in 1938, a paleontologist from New York City excavated a large section of the tracks. He found the first ever Sauropod tracks.
That's a dinosaur that has front feet like an elephant, but hind feet like a reptile.
The limestone that was carried away is still a prominent exhibit at New York's famed American Museum of Natural History.
Glen Rose, the county seat of Somervell County, is located about an hour southwest of Fort Worth.
The state park is open 7 a.m. to 10 p.m. and includes areas for overnight camping. Admission is $7 for adults and free for children 12 years and younger.
