Last year, I blogged about my family's prehistoric experience at Dinosaur Valley State Park, near Glen Rose. Laurie Jasinski's coverage of the 100th anniversary of the tracks' discovery in June Speaking of Texas inspired our most recent dino fix, a trip to the Texas Natural Science Center, in the Texas Memorial Museum on the UT-Austin campus. Outside the museum, a small building houses some of the Glen Rose sauropod and theropod tracks (awaiting restoration), among the finest examples of dinosaur trackways ever discovered. Inside, we explored the natural science of Texas on four floors, my six-year-old gravitating to the Hall of Geology and Paleontology. Here, impressive displays range from a 90-million-year-old (30 foot) mosasaur, which swam in the sea that once covered this area, to multiple meteorites that have showered the state. My son even brought along fossils he'd found in Brushy Creek for inspection by the staff paleontologist on duty. We started and ended our tour gawking at the Texas Pterosaur suspended from the ceiling of the Great Hall. With its 40-foot wingspan, the largest flying creature ever discovered, once soared over the Big Bend area. How did this giant ever get off the ground!
