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 ...
Species: C. penicillatus. Binomial name. Chaetodipus penicillatus. (Woodhouse, 1852) The desert pocket mouse (Chaetodipus penicillatus) is a North American species of heteromyid rodent found in the southwestern United States and Mexico. [2] True to its common name, the medium-sized desert pocket mouse prefers sandy, sparsely vegetated desert ...
Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish ...
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.
Chaetodipus penicillatus. Chaetodipus pernix. Chaetodipus rudinoris. Chaetodipus spinatus. Chaetodipus is a genus of pocket mice containing 17 species endemic to the United States and Mexico. [1] Like other members of their family such as pocket mice in the genus Perognathus, they are more closely related to pocket gophers than to true mice.
The desert sucker is found in Nevada, Utah, Arizona and New Mexico. [2] [4] The desert sucker occurs in the lower Colorado River basin, below the Grand Canyon, particularly in the Gila River, and above the Grand Canyon in streams in the Virgin River basin, the White River basin and others. The total range area of the desert sucker is estimated ...
Found mainly in rocky outcrops in the deserts of the southwestern United States and Mexico, the rock pocket mouse is medium-sized (length ~18 cm, weight ~12–18g) and nocturnal. It eats mainly plant seeds and makes small burrows in soil close to or under rocks to evade owls, its main predator. The breeding season spans a few months, starting ...
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.
