During the early Paleozoic, southern and western New Mexico were submerged by a warm shallow sea that would come to be home to creatures including brachiopods, bryozoans, cartilaginous fishes, corals, graptolites, nautiloids, placoderms, and trilobites. During the Ordovician the state was home to algal reefs up to 300 feet high.

The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, and the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years.

Marine coastal ecosystem. A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Marine coastal ecosystems include many very different types of marine habitats, each with their own characteristics and species composition. They are characterized by high levels of biodiversity and productivity.
The Blue Hole is a clear blue body of water with a constant 62 °F (17 °C) temperature and constant inflow of 3,000 US gallons per minute (11 m 3 /min; 2,500 imp gal/min), enough to cycle out the water every six hours. While the surface is only 80 feet (24 m) in diameter, it expands to a diameter of 130 feet (40 m) at the bottom.
Map of Mesozoic exposures in New Mexico, USA. The Mesozoic began with the Permian-Triassic extinction event. [31] The Sevier and Nevadan orogenies pushed up mountains to the west of New Mexico that produced a rain shadow, giving New Mexico an exquisitely hot and dry climate through much of the early Mesozoic. [32] [33]
Up to half of the continent's modern surface area may have been submerged by this sea. [72] This is called the Western Interior Seaway. [73] It covered the majority of states like Texas, New Mexico, Oklahoma, Colorado, Kansas, Nebraska, the Dakotas, and Wyoming. [74] The seafloor was smooth and probably never submerged by more than 600 feet of ...
