Cnemidophorus
''Cnemidophorus'' is a genus of lizards in the family Teiidae. Species in the genus ''Cnemidophorus'' are commonly referred to as whiptail lizards or racerunners. The genus is endemic to South America, Central America, and the West Indies. Taxonomy Reeder et al. (2002) re-examined the nomenclature for the genus ''Cnemidophorus'' (''sensu lato'') and split it into the two genera ''Aspidoscelis'' and ''Cnemidophorus'' (''sensu stricto''). A further split by Harvey et al. (2012) added the genera ''Ameivula'' and '' Contomastix''. Etymology The name ''Cnemidophorus'' literally means "greave-wearing", from the Ancient Greek ' (combining form of ', "greave", a leg armor) and ' ("bearer"). Reproduction In some of the ''Cnemidophorus'' species, there are no males, and they reproduce through parthenogenesis. This is well known in bees and aphids, but is very rare in vertebrates. Those species without males are now known to originate through hybridization, or interspecific breeding. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blastomeryx

While ''Blastomeryx'' (as well as modern musk deer) lacked antlers, a Middle Miocene species had bony knobs on its skull, which have been interpreted as incipient horns.

Archaeohippus
''Archaeohippus'' (Greek: "ancient" (archaios), "horse" (hippos)) is an extinct three toed member of the family Equidae known from fossils of early Oligocene to middle Miocene age. The genus is noted for several distinct skeletal features. The skull possesses deeply pocketed fossa in a notably long preorbital region. The genus is considered an example of phyletic dwarfism with adults estimated at being on average 20 kg in weight. This is in contrast to the most common equid of the period, ''Miohippus''. Characters of the teeth show a mix of both primitive and advanced traits. The advanced traits are very similar to those shown in the genus ''Parahippus''. The noted similarities of ''Archaeohippus'' and ''Parahippus'' show them to be descended from a common ancestor and are considered sister species. Taxonomic history The first species to be named was found in the Miocene Mascall Fauna of Cottonwood Creek, Oregon. Named '' Anchitherium ultimus'' the species was described in 1886 ...

Aphelops
''Aphelops'' (Greek: "smooth" (apheles), "face" (ops), in a reference of lacking a horn) is an extinct genus of hornless rhinoceros endemic to North America. It lived from the Middle Miocene to the early Pliocene, during which it was a common component of North American mammalian faunas along with ''Teleoceras''. Description On the basis of skull size, the largest species of ''Aphelops'' is ''A. mutilus'' (which is the largest North American rhinoceros) and the smallest is the type species ''A. megalodus''. ''A. mutilus'' has been estimated to have weighed , and ''A. malacorhinus'' has been estimated at . ''Aphelops'' can be distinguished by other members of the Aceratheriinae by two traits: the arched top of the skull, and the long diastema (gap) between the second incisor (lower tusk) and first premolar. Many other aspects of its anatomy are typical of aceratheriines, including: the absence of a horn on the broad, unfused nasal bones; the reduced premaxilla and lost first ...

Anchitherium
''Anchitherium'' (meaning ''near beast'') was a fossil horse with a three-toed hoof. ''Anchitherium'' was a browsing (leaf eating) horse that originated in the early Miocene of North America and subsequently dispersed to Europe and Asia,(in Chinese with English summary).MacFadden, B.J. 2001. Three-toed browsing horse ''Anchitherium clarencei'' from the early Miocene (Hemingfordian) Thomas Farm, Florida.

Procyon (genus)
''Procyon'' is a genus of nocturnal mammals comprising three species commonly known as raccoons in the family Procyonidae. The most familiar species, the common raccoon (''P. lotor''), is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and less well known. Genetic studies have shown that the closest relatives of raccoons are the ring-tailed cats and cacomistles of genus ''Bassariscus'', from which they diverged about 10 million years ago. General attributes Raccoons are unusual, for their thumbs (though not opposable) enable them to open many closed containers (such as garbage cans and doors). They are omnivores with a reputation for being clever and mischievous; their intelligence and dexterity equip them to survive in a wide range of environments and are one of the few medium-to-large-sized animals that have enlarged their range since human encroachment began (another is the coyote). Raccoon hindfeet are pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borophaginae
The extinct Borophaginae form one of three subfamilies found within the canid family. The other two canid subfamilies are the extinct Hesperocyoninae and extant Caninae. Borophaginae, called "bone-crushing dogs", were endemic to North America during the Oligocene to Pliocene and lived roughly 34—2.5 million years ago, existing for about . Origin The Borophaginae descended from the subfamily Hesperocyoninae. The earliest and most primitive borophagine is the genus ''Archaeocyon'', which is a small fox-sized animal mostly found in the fossil beds in western North America. The borophagines soon diversified into several major groups. They evolved to become considerably larger than their predecessors, and filled a wide range of niches in late Cenozoic North America, from small omnivores to powerful, bear-sized carnivores, such as ''Epicyon''. Species There are 66 identified borophagine species, including 18 new ones that range from the Orellan to Blancan ages. A phylogenetic anal ...
