How long ago was Texas under the ocean?
265 million years ago
Back when these life-forms were alive—265 million years ago or so—the Guadalupe Mountains were underwater, part of a flourishing reef that once stretched about 400 miles around the edge of a long-vanished sea. Reefs are a fascinating fusion of biology and geology.

Because much of Texas was covered by the Western Interior sea about 100 million years ago in the late Cretaceous Period. Texas was on the eastern coast of the landmass called Laramidia. Texas is part of the plains region of North America that extends up into northern Canada.
Was El Paso Texas ever under water?

What dinosaurs are still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Can you find dinosaur bones in Texas?
Today, fossilized remnants of this world can be found along creek banks, shallow pits, and other sites that stretch from the Red River, through Glen Rose, and out toward the Rio Grande Valley in West Texas. …

Once upon a time, about 260 million years ago, the land before Texas was not really land at all. In fact, Texas was completely covered by ocean.
What is the best example of an ancient reef in Texas?
Indeed, the pyramids were built mostly of limestone quarried from one. But the Guadalupe Mountains of west Texas and New Mexico are one of the best examples of an ancient reef anywhere. In honor of this, they were made a national park in 1972.
How were the barrier islands formed in Texas?
With sea level at a still stand, ongoing wave action and longshore drift deposited sand and shell hash parallel to the mainland, forming the modern chain of barrier islands (Padre, Mustang, San Jose, and Matagorda Islands along the middle and lower Texas coast and Galveston Island and Bolivar Peninsula along the upper Texas coast).
How were the coastal bays of Texas formed?
The flooding of the valleys of major streams, such as the Trinity, Lavaca, Guadalupe, Aransas, and Nueces Rivers created the earliest forms of our modern coastal bays (respectively, Galveston, Matagorda, San Antonio, Copano, and Corpus Christi Bays).
