The Arlington Archosaur Site doesn’t fit the traditional vision of a remote fossil deposit situated in rocky, windswept badlands. Rich in turtle, crocodile, fish, and dinosaur remains, the assemblage is within walking distance of a Starbucks in the Arlington, Texas, metro area. But those fossils tell of a very different time — a snapshot of life roughly 95 million years ago, when Texas was on the coast of a warm, shallow seaway that cleft North America in two.
