After the Dinosaurs: A Texas Tropical Paradise Recovered at Lake Casa Blanca
During the Eocene Epoch some 42 million years ago--about 20 million years after the demise of the dinosaurs--the area that today is the Lake Casa Blanca International State Park near Laredo was a tropical forest/coastal mangrove environment. Excavations at the site by Dr. James Westgate and his Lamar University students have uncovered fossils of 29 extinct mammal species and about as many species of crocodiles, turtles, sharks, rays, and giant water snakes. In this book, he reconstructs a clear picture of prehistoric life at Lake Casa Blanca, illustrated with drawings and paintings by Abby Salazar, a recent earth science graduate now pursuing a second degree in art.
