Dallas — and much of Texas — was once submerged by a sprawling, blue-water ecosystem called the Western Interior Seaway, which split North America in two from the Gulf of Mexico to the Arctic Ocean, according to a new video documentary by the Discovery Channel.
“Prehistoric Dallas” includes commentary from two SMU paleontologists, Michael J. Polcyn and Louis L. Jacobs, both of whom have expertise in Texas’ ancient sea and the life that inhabited it from more than 90 million years ago until the extinction of the dinosaurs at 66 million years ago.
