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 ...
Bursera microphylla. Bursera microphylla, known by the common name elephant tree in English or ' torote' in Spanish, is a tree in the genus Bursera. It grows into a distinctive sculptural form, with a thickened, water-storing or caudiciform trunk. It is found in the southwestern United States and northwestern Mexico.
The Gila Wilderness is located in southwest New Mexico, north of Silver City and east of Reserve. It contains the West Fork, Middle Fork and much of the East Fork of the Gila River; riverside elevations of around 4,850 feet (1,480 m) are the lowest in the wilderness. The Mogollon Mountains traverse an arc across the wilderness.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates. [1][2] At lower elevations, junipers often predominate and trees are spaced widely ...
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 ...
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 ...
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.
The ancient sea, which existed from the early Late Cretaceous (100 Ma) to the earliest Paleocene (66 Ma), connected the Gulf of Mexico to the Arctic Ocean. The two land masses it created were Laramidia to the west and Appalachia to the east. At its largest extent, it was 2,500 feet (760 m) deep, 600 miles (970 km) wide and over 2,000 miles ...
