From the Miocene to Pliocene New Mexico was home to creatures such as four-tusked relatives of modern elephants. Other inhabitants included an abundance of beavers, three-toed horses, and rhinoceroses. Trees growing in New Mexico have been preserved as petrified wood, some specimens have opalized into a gem-like substance. [16]
Small, primitive maize cobs have been found at five different sites in New Mexico and Arizona. The climatic range of the sites is wide as they range from the Tucson basin in the Arizona desert, at an elevation of 700 m (2300 ft), to a rocky cave on the Colorado Plateau at 2200 m (7200 ft). That suggests that the primitive maize they grew was ...

Larrea tridentata is a prominent species in the Mojave, Sonoran, and Chihuahuan Deserts of western North America, and its range includes those and other regions in portions of southeastern California, Arizona, southern Nevada, southwestern Utah, New Mexico, and Texas in the United States, and Chihuahua, Sonora, Coahuila, Nuevo León, Zacatecas ...
Folsom site. Folsom site or Wild Horse Arroyo, designated by the Smithsonian trinomial 29CX1, is a major archaeological site about 8 miles (13 km) west of Folsom, New Mexico. It is the type site for the Folsom tradition, a Paleo-Indian cultural sequence dating to between 11000 BC and 10000 BC. The Folsom site was excavated in 1926 and found to ...
Note the two sieves catching charred seeds and charcoal, and the bags of archaeological sediment waiting for flotation. Paleoethnobotany (also spelled palaeoethnobotany), or archaeobotany, is the study of past human-plant interactions through the recovery and analysis of ancient plant remains. Both terms are synonymous, though paleoethnobotany ...
Timeline of fish evolution. The evolution of fishes took place over a timeline which spans the Cambrian to the Cenozoic, including during that time in particular the Devonian, which has been dubbed the "age of fishes" for the many changes during that period. The Late Devonian extinctions played a crucial role in shaping the evolution of fish ...
The Sierra Madre Occidental pine–oak forests (Spanish: Bosques de pino-roble de la Sierra Madre Occidental) are a Temperate broadleaf and mixed forests ecoregion of the Sierra Madre Occidental range from the southwest USA region to the western part of Mexico. They are home to a large number of endemic plants and important habitat for wildlife.
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
