Dinosaur Fossils are not found in Indiana (PA-11)
Many animals suddenly became extinct at the end of the Cretaceous Period, about 70 million years ago. Dinosaurs, flying and gliding reptiles, most marine reptiles, most shelled cephalopods, and other invertebrates vanished. Todays reptiles are lizards, turtles, snakes, alligators and crocodiles. Birds evolved late and are the dinosaurs true descendants. Although dinosaurs probably lived in Indiana, the bedrock and sediments that would have contained their remains have long since been removed. The youngest bedrock in Indiana is far too old to contain dinosaur fossils. Kansas and New Jersey are the nearest known localities of dinosaur remains.
