A Treasure Trove of FossilsAbundant fossils in Big Bend, including some found nowhere else in the world, record the existence and demise of dinosaurs and the flourishing of mammals, enabling us to ponder evolution and our impermanence in the world. The park preserves a largely intact 130 million year slice of geologic time, including the dinosaur extinction event. Some of Big Bend's fossil finds include bones of a giant pterosaur, the largest known flying creature of all time with a 36-foot wingspan, as well as the massive skull of the giant horned dinosaur Bravoceratops (only discovered in 2013, and only known from Big Bend).
