Crawford's Gray Shrew
Crawford's gray shrew (''Notiosorex crawfordi''), also known as the desert shrew, is a small shrew found in the southwestern United States and northern Mexico. It is a member of the family Soricidae of the order Eulipotyphla. It was the only known member of the genus '' Notiosorex'' until two species, ''N. villai'' distributed in the Mexican state of Tamaulipas, and ''N. evotis'' distributed along the northwest coast of Mexico, were named. A fourth distinct species, ''N. cockrumi'', was discovered in the U.S. state of Arizona and named in 2004. Description Crawford's gray shrew is one of the smallest desert mammals and one of the world's smallest homeotherms. When fully grown, it will only grow to a size of about long, half of which is the tail, and it will only grow to a weight of about . It is gray-brown with light gray under parts. The long tail is gray with it being lighter underneath. It has small, but relatively prominent, ears. A Crawford's gray shrew is born during ...

Its range extends from Arizona to central portion of the Mexican state of Sonora Sonora (), officially Estado Libre y Soberano de Sonora (), is one of the 31 states which, along with Mexico City, comprise the Administrative divisions of Mexico, Federal Entities of Mexico. The state is divided into Municipalities of Sonora, 72 .... Distribution and habitat The shrew is found in desert habitats from southeastern and south-central Arizona to central Sonora. It typically inhabits desert shrub, and plant communities dominated by mesquite, agave, cholla, and oakbrush. It burrows in the soil or in fallen logs and debris. Characteristics The shrew is very small and is insectivorous. It has a brown-gray color with a reddish-pin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Villa's Gray Shrew
Villa's gray shrew (''Notiosorex villai'') is a shrew native to northeastern Mexico, where it is called ''musaraña''. It is assessed vulnerable by the IUCN due to its small extent of occurrence and degradation of habitat. Taxonomy The shrew was formerly considered to be a part of N. crawfordi, but is now considered a distinct species. Distribution and habitat Currently it is known to occur in only three locations in two isolated mountain valleys. It is known to inhabit pine-oak forest, tropical forest and riparian forest. The species may have a larger extent of occurrence than is currently known. Conservation The species has been assessed as vulnerable by the IUCN Red List. Threats to the species include its small extent of habitats, habitat degradation, overgrazing, and agricultural activities. The species probably inhabits the western part of the El Cielo Biosphere Reserve in the Mexican state of Tamaulipas Tamaulipas, officially the Free and Sovereign State of ...

Soricinae
The red-toothed shrews of the subfamily Soricinae are one of three living subfamilies of shrews, along with Crocidurinae (white-toothed shrews) and Myosoricinae (African white-toothed shrews). In addition, the family contains the extinct subfamilies Limnoecinae, Crocidosoricinae, Allosoricinae and Heterosoricinae. These species are typically found in North America, northern South America, Europe and northern Asia. The Tooth enamel, enamel of the tips of their teeth is reddish due to iron pigment. The iron deposits serve to harden the enamel and are concentrated in those parts of the teeth most subject to wear. Members of the genera ''Chimarrogale'', ''Nectogale'', ''Neomys'' (Nectogalini) and some members of ''Sorex'' (Soricini) are known as water shrews, due to having a semi-aquatic lifestyle. Species The list of species is: * Tribe Anourosoricini ** Genus ''Anourosorex'' (Asian mole shrews) *** Assam mole shrew, ''A. assamensis'' *** Giant mole shrew, ''A. schmidi'' *** Chines ...

Notiosorex Harrisi
''Notiosorex harrisi'' is an extinct species of shrew from the subfamily Soricinae. It is one of several extinct species of ''Notiosorex'' described from the fossil record and the specific epithet is a patronymic to honor Arthur H. Harris for his decades of work on the paleontology of mammals in the southwestern United States. Holotype The holotype specimen is deposited at the University of Texas at El Paso Biodiversity Collections as UTEP:ES:120-2526. It is an adult, left dentary with the first incisor, fourth premolar and first through third molars. The specimen was collected from Big Manhole Cave in Eddy County, New Mexico Eddy County is a List of counties in New Mexico, county located in the U.S. state of New Mexico. As of the 2020 United States census, 2020 census, the population was 62,314. Its county seat and largest city is Carlsbad, New Mexico, Carlsbad. T ....

Notiosorex Dalquesti
''Notiosorex dalquesti'', or Dalquest's shrew, is an extinct species of shrew that was found in the southwestern United States and northern Mexico during the Pleistocene and possibly the Holocene. Fossils of Dalquest's shrew were once thought to belong to the living Crawford's gray shrew Crawford's gray shrew (''Notiosorex crawfordi''), also known as the desert shrew, is a small shrew found in the southwestern United States and northern Mexico. It is a member of the family Soricidae of the order Eulipotyphla. It was the only k ... but have since been classified as a distinct species.

Shrew (animal)
Shrews (family Soricidae) are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders. Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are. It is, in fact, a much closer relative of hedgehogs and moles; shrews are related to rodents only in that both belong to the Boreoeutheria magnorder. Shrews have sharp, spike-like teeth, whereas rodents have gnawing front incisor teeth. Shrews are distributed almost worldwide. Among the major tropical and temperate land masses, only New Guinea, Australia, New Zealand, and South America have no native shrews. However, as a result of the Great American Interchange, South America does have a relatively recently naturalised population, present only in the northern Andes. The shrew family has 385 known species, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
