The geology of New Mexico includes bedrock exposures of four physiographic provinces, with ages ranging from almost 1800 million years (Ma) to nearly the present day. Here the Great Plains, southern Rocky Mountains, Colorado Plateau, and Basin and Range Provinces meet, giving the state great geologic diversity.
Albuquerque Basin. The Albuquerque Basin (or Middle Rio Grande Basin[1]) is a structural basin and ecoregion within the Rio Grande rift in central New Mexico. It contains the city of Albuquerque. Geologically, the Albuquerque Basin is a half-graben that slopes down towards the east to terminate on the Sandia and Manzano mountains. [2]
The early Paleocene trumpetfish Eekaulostomus from Palenque, Mexico. The small pelagic fish population recovered rather quickly, and there was a low extinction rate for sharks and rays. Overall, only 12% of fish species went extinct. [182]
Geography. The Tularosa Basin is located primarily in Otero County, New Mexico. It covers about 6,500 sq mi (16,800 km 2) (35% larger than Connecticut). It lies between the Sacramento Mountains to the east, and the San Andres and Oscura Mountains to the west. The basin stretches about 150 mi (240 km) north–south, and at its widest is about 60 ...
Capitan Reef in Guadalupe Mountains National Park. The Capitan Formation is a geologic formation found in western Texas and southeastern New Mexico. It is a fossilized reef dating to the Guadalupian Age of the Permian period. The formation underlies El Capitan in Guadalupe Mountains National Park, [1] and the formation and its associated basin ...
Coelacanth. Coelacanths (/ ˈsiːləkænθ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2][3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
Knightia is an extinct genus of clupeid bony fish that lived in the freshwater lakes and rivers of North America and Asia during the Eocene epoch. The genus was erected by David Starr Jordan in 1907, in honor of the late University of Wyoming professor Wilbur Clinton Knight, "an indefatigable student of the paleontology of the Rocky Mountains."

Paleontology in New Mexico refers to paleontological research occurring within or conducted by people from the U.S. state of New Mexico. The fossil record of New Mexico is exceptionally complete and spans almost the entire stratigraphic column. [1] More than 3,300 different kinds of fossil organisms have been found in the state.
