El Captian, Guadalupe Mountains, Texas

This limestone promontory is, in fact, a 260-million-year-old coral reef from the Peremian. The sea life that made up this ancient reef – species of sponge, corals, brachiopods, crinoids, fusulinids, ammonoids, etc. – was drive almost entirely extinct by the end of the Permian

During the Ordovician, a vast tropical sea covered most of the present-day North America, in most places perhaps not much more than ankle - or knee-deep. Wading into the water on a sandy tropical beach in Wisconsin, you could keep trudging across mots of the continent with your head above water before the seafloor dropped into deep somewhere around Texas. This vast shallow province has been grandly dubbed the Great American Carbonate Bank – a nationwide Bahama. Sea levels wre possibly the highest in the history of complex life, and the shallow seas that drowned the continents were jammed with life. Flooded North America was rotated clockwise almost 90 percent, California nd the entire West coast simply didn’t exist, and chunks of New England, the Canadian Maritimes, England, and Wales – recently divorced from Africa ner the South Pole – were an island chain called Avalonia not unlike modern Japan. Avalonia was then far away from the rest of North America, across the doomed lapetus Ocean, the ancestor of the Atlantic. ~ Page 31
