The location of the state of New Mexico. 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 ...
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 ...
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 ...
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 ...
The Permian (/ ˈ p ɜːr m i. ə n / PUR-mee-ən) [4] is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya.
The Sandia Mountains are the most visited range in New Mexico. Numerous hiking trails exist on both sides of the range, such as the popular La Luz Trail and Crest Trail. Much of the west side of the range is included in the Sandia Mountain Wilderness; the trails on that side are steeper, and water is very scarce.
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.
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 ...
