Floridaceras
''Floridaceras'' is an extinct genus of rhinocerotid of the Miocene epoch (early Hemingfordian), endemic to North America, living from around ~20.6–16.3 Ma, existing for approximately . Taxonomy ''Floridaceras'' was named by Wood (1964). Its type is ''Floridaceras whitei''. It was assigned to Rhinocerotidae by Wood (1964) and Carroll (1988); and to Aceratheriinae by Prothero (1998). Fossil distribution The only site known is the Thomas Farm Site in Gilchrist County, Florida, ~20.6–16.3 Ma. Description ''Floridaceras'' was of unusually large size for a rhinoceros of the Hemingfordian. It would have been roughly comparable to a black rhinoceros The black rhinoceros (''Diceros bicornis''), also called the black rhino or the hooked-lip rhinoceros, is a species of rhinoceros native to East Africa, East and Southern Africa, including Angola, Botswana, Eswatini, Kenya, Lesotho, Malawi, Moza ... in size, much larger than contemporaries such as the '' Menoceras''.

Rhinocerotidae
A rhinoceros ( ; ; ; : rhinoceros or rhinoceroses), commonly abbreviated to rhino, is a member of any of the five extant taxon, extant species (or numerous extinct species) of odd-toed ungulates (perissodactyls) in the family (biology), family Rhinocerotidae; it can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea. Two of the extant species are native to Africa, and three to South Asia, South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh over half a tonne in adulthood. They have a herbivore, herbivorous diet, small brains for mammals of their size, one or two horns, and a thick , protective skin formed from layers of collagen positioned in a crystal structure, lattice structure. They generally eat leafy material, although their ability to ferment food in their colon (anatomy), hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aceratheriinae
Aceratheriinae is an extinct subfamily of rhinoceros endemic to Asia, Africa, Europe, and North America, from the Oligocene through the Pliocene. It lived from 33.9 to 3.4 mya, existing for approximately . Taxonomy Aceratheriinae was named by Dollo (1885). It was assigned to Rhinocerotida by Codrea (1992); and to Rhinocerotidae by Prothero (1998), Antoine et al. (2000), Kaya and Heissig (2001), Sach and Heizmann (2001) and Deng (2005).P.-O. Antoine, C.

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] |
Florida Museum Of Natural History
The Florida Museum of Natural History (FLMNH) is Florida's official state-sponsored and chartered natural history museum. Its main facilities are located at 3215 Hull Road on the campus of the University of Florida in Gainesville, Florida, Gainesville. The main public exhibit facility, Powell Hall and the attached McGuire Center, is located in the Cultural Plaza, which it shares with the Samuel P. Harn Museum of Art and the Curtis M. Phillips Center for the Performing Arts. The main research facility and former public exhibits building, Dickinson Hall, is located on the east side of campus at the corner of Museum Road and Newell Drive. On April 18, 2012, the American Institute of Architects's Florida chapter placed Dickinson Hall on its list of Florida Architecture: 100 Years. 100 Places as the Florida Museum of Natural History / Formerly Florida Museum of Natural Sciences.

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Hemingfordian
The Hemingfordian on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 20,600,000 to 16,300,000 years BP. It is usually considered to overlap the latest Aquitanian and Burdigalian of the Early Miocene. The Hemingfordian is preceded by the Arikareean and followed by the Barstovian NALMA stages. The Hemingfordian can be further divided into the substages of: *Late/Upper Hemingfordian: Lower boundary source: base of Burdigalian The Burdigalian is, in the geologic timescale, an age (geology), age or stage (stratigraphy), stage in the early Miocene. It spans the time between 20.43 ± 0.05 annum, Ma and 15.97 ± 0.05 Ma (million years ago). Preceded by the Aquitanian (sta ...

Annum
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gilchrist County is included in the Gainesville, Florida Gainesville, Florida metropolitan area, Metropolitan Statistical Area. History Gilchrist County was created in 1925, the last county organized in Florida. It was originally set to be named Melon County due to watermelons being one of the main exports from the area; however, the death of Albert W. Gilchrist, Governor of Florida from 1909 to 1913, prompted its renaming to Gilchrist County instead. It was formed by residents of what was then western Alachua County, as they believed they were not getting adequate representation on the county ...
