Yumaceras
''Yumaceras'' is an extinct genus of antelope-like palaeomerycid artiodactyl endemic to North America from the Miocene epoch, 13.6—5.33 Ma, existing for approximately . Taxonomy ''Yumaceras'' was named by Frick (1937). It was synonymized subjectively with ''Pediomeryx'' by Savage (1941) and Janis and Manning (1998); it was reranked as ''Pediomeryx'' (''Yumaceras'') by Webb (1983); it was synonymized subjectively with ''Cranioceras'' by Tedford ''et al.'' (1987). It was assigned to ''Pediomeryx'' by Webb (1983); and to Cranioceratini by Prothero and Liter (2007).D. R. Prothero and M. R. Liter. 2007. Family Palaeomerycidae. in D. R. Prothero and S.

Haile Quarry Site
The Haile Quarry or Haile sites are an Early Miocene and Pleistocene assemblage of vertebrate fossils located in the Haile quarries, Alachua County, northern Florida. The assemblage was discovered during phosphate mining, which began in the late 1940s. Haile sites are found in the Alachua Formation. Two sites within the Ocala Limestone yielded Upper Eocene Valvatida (sea stars) and mollusks. University of Florida and Florida Museum of Natural History paleontologists numbered the Haile fossil sites with Arabic and Roman numbers and letters in order to define locations more distinctly. UF scientists used Roman numbering and the FLMNH scientists used Arabic.

Palaeomerycidae
The Palaeomerycidae are an extinct family of ruminants in the order Artiodactyla. Palaeomerycids lived in North America, Europe, Africa and Asia from 33 to 4.9 million years ago (from the Late Eocene to Pliocene epochs), existing for about 28 million years; one species was also reported from South America, but its identity as a palaeomerycid was subsequently disputed. Specimens of '' Amphitragulus'', the earliest known genus, have been found in Aragon (Spain), Ronheim (Germany), Sardinia (Italy), France, and Kazakhstan and range from 33 to 15.97 million years old. Fossils of '' Lagomeryx'' and ''Palaeomeryx feignouxi'' were recovered in Germany and Slovakia from the Middle Eocene. The oldest known North American specimen, '' Barbouromeryx'', was discovered in Scotts Bluff, Nebraska, and estimated at 23.03 million years old. Palaeomerycids such as ''Cranioceras'' and other Dromomerycinae continued to live in North America until the early Pliocene. Description Palaeomerycids w ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Miocene Mammals Of North America
The Miocene ( ) is the first geological epoch of the Neogene The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. ... 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 is preceded by the Oligocene and is followed by 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 a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch.

Prehistoric Cervoids
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artifacts from the Archaic period (8000 - 2000 BCE) have been found at several sites in Alachua County. Permanent settlements appeared in what is now Alachua County around 100 CE, as people of the wide-ranging Deptford culture developed the local Cades Pond culture. The Cades Pond culture gave way ...
