Tapirus Haysii
''Tapirus haysii'' is an extinct species of tapir that inhabited North America during the early to middle Pleistocene Epoch (~2.5–1 Ma). These fossil remains of two juvenile ''T. haysii'' were collected in Hillsborough County, Florida on 31 August 1963. It was classified as the second largest North American tapir; the first being '' T. merriami''. Taxonomy ''Tapirus copei'' is a junior synonym. ''Taprirus haysii'' is placed in the subgenus ''Helicotapirus'', which also includes ''Tapirus veroensis'' and ''Tapirus lundeliusi ''Tapirus lundeliusi'' is an extinct species of tapir that lived in Florida in the early Pleistocene The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11 ....''

Early Pleistocene
The Early Pleistocene is an unofficial epoch (geology), sub-epoch in the international geologic timescale in chronostratigraphy, representing the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 annum, Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian, Gelasian Age and the Calabrian (stage), Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene respectively. The Chibanian provisionally spans time from 773 ka to 126 ka, and the Tarantian from then until the definitive end of the whole Pleistocene, c. 9700 BC in the 10th millennium BC. Notes {{Ge ...

Middle Pleistocene
The Chibanian, more widely known as the Middle Pleistocene (its previous informal name), is an Age (geology), age in the international geologic timescale or a Stage (stratigraphy), stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.7741 annum, Ma (774,100 years ago) and 0.129 Ma (129,000 years ago), also expressed as 774.1–129 ka. It includes the transition in palaeoanthropology from the Lower Paleolithic, Lower to the Middle Paleolithic over 300 ka. The Chibanian is preceded by the Calabrian (stage), Calabrian and succeeded by the Late Pleistocene. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. Its end roughly coincides with the termination of the Penultimate Glacial Period and the onset of the Last Interglacial period (correspondin ...

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 ...

Tapir
Tapirs ( ) are large, herbivorous mammals belonging to the family Tapiridae. They are similar in shape to a Suidae, pig, with a short, prehensile nose trunk (proboscis). Tapirs inhabit jungle and forest regions of South America, South and Central America and Southeast Asia. They are one of three extant branches of Perissodactyla (odd-toed ungulates), alongside Equidae, equines and rhinoceroses. Only a single genus, ''Tapirus'', is currently extant. Tapirs migrated into South America during the Pleistocene epoch from North America after the formation of the Isthmus of Panama as part of the Great American Interchange. Tapirs were formerly present across North America, but became extinct in the region at the end of the Late Pleistocene, around 12,000 years ago. Name The term ''tapir'' comes from the Portuguese language, Portuguese-language words , , which themselves trace their origins back to Old Tupi, specifically the term .

Pleistocene Epoch
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Tapirus Merriami
''Tapirus merriami'', commonly called Merriam's tapir, is an extinct species of tapir which inhabited North America during the Pleistocene. Early history Tapirs have a long history on the North American continent. Fossils of ancient tapirs in North America can be dated back to 50 million-year-old Eocene rocks on Ellesmere Island, Canada, which was then a temperate climate. By 13 million years before present, tapirs very much like extant tapirs existed in Southern California.M. Colbert and R. Schoch 1998. Tapiroidea and other moropomorphs. In: C. Janis, K. Scott, L. Jacobs, (eds) Evolution of Tertiary Mammals of North America. Volume I: Terrestrial carnivores, ungulates, and ungulate like mammals. Cambridge University Press. During the Pleistocene epoch, four species of tapir are known to have inhabited North America. Along with ''T. merriami'', '' Tapirus californicus'' also lived in California, ''Tapirus veroensis'' was found in Florida, Georgia, Kansas, Missouri and Tennessee, ...

Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...

Tapirus Veroensis
''Tapirus veroensis'' is an extinct tapir species that lived in the area of the modern eastern and southern United States during the Pleistocene epoch (Irvingtonian-Rancholabrean). ''Tapirus veronensis'' is thought to have gone extinct around 11,000 years ago. History The first complete skull with full dentition of ''T. veroensis'' fossil was found at Vero Beach, Florida, in 1915 and named in 1918 by the Florida State Geologist E. H. Sellards. Fragmentary specimens had been described by Leidy as early as 1852. Taxonomy The taxonomy of Pleistocene North American tapirs has long been the subject of confusion, with many named species now recognised as synonyms of ''T. veroensis''. ''Tapirus veroensis'' is the type species of the subgenus ''Helicotapirus'', which includes several other species of extinct tapir from North America like ''Tapirus lundeliusi, T. lundeliusi'' and ''Tapirus haysii, T. haysii.''

Prehistoric Tapirs
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded.

Quaternary Mammals Of North America
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused.
