Bison antiquus is an extinct species of bison that lived in North America during the Late Pleistocene from over 60,000 years ago until around 10,000 years ago. Bison antiquus was one of the most common large herbivores in North America during this time period. It is the direct ancestor of the living American bison. [1] [2]
The first described remains of Bison antiquus were collected at Big Bone Lick, Kentucky in Pleistocene deposits in the 1850s and only consisted of a fragmentary posterior skull and a nearly complete horn core. [3] The fossil (ANSP 12990) was briefly described by Joseph Leidy in 1852. [4] Although the original fossils were fragmentary, a complete skull of an old male was discovered in southern California and were described as a new species, B. californicus, by Samuel Rhoads in 1897, [5] but the species is considered synonymous with B. antiquus. [6] : 759–760 Since the 19th century, several well preserved specimens of B. antiquus have been discovered in many parts of the United States, [7] Canada, [8] and southern Mexico. [9]
Bison antiquus is known from fossils found across North America south of the Laurentide Ice Sheet (whose southernmost extent is around the modern United States-Canada border), ranging from southern Canada (southern Alberta [8] and Ontario [10] ) in the north, and Washingon State [11] and California [12] in the west, southwards to Southern Mexico [9] and eastwards to South Carolina and Florida. [13]
Compared to the living American bison (Bison bison). B. antiquus was considerably larger and had longer limbs, with the upper limbs being more slender while the lower limbs were more robust. The skull was also somewhat more elongate and less domed than that of American bison. [10] It reached up to 2.27 m (7.4 ft) tall, 4.6 m (15 ft) long, and a weight of 1,588 kg (3,501 lb), with an average of around 800 kg (1,800 lb). [14] [15] The horns were also considerably larger than those of living American bison and differed somewhat in shape, [10] being on average 87 centimetres (2.85 ft) across tip to tip, but could be as much as 106.7 centimetres (3.50 ft) across. [8]
Unlike living American bison, which are almost exclusively grazers, [16] dental wear analysis suggests that Bison antiquus was a variable mixed feeder (both browsing and grazing) with an adaptable diet depending on geographical location, with diets varying from strict grazing to mixed feeding. [17] [18] [12] Bison antiquus was likely preyed upon by large carnivores, which may have included the American lion (Panthera atrox), [19] the sabertooth cat Smilodon fatalis, [20] and dire wolves (Aenocyon dirus). [21]
Around 195,000-130,000 years ago, the steppe bison (Bison priscus) crossed the Bering Land Bridge into North America. [22] In North America, B. priscus evolved into the large long-horned Bison latifrons , which then gave rise to B. antiquus sometime prior to 60,000 years ago. [23] B. antiquus became increasingly abundant in parts of midcontinent North America from 18,000 until about 10,000 years ago. [24]
A number of sites document the exploltation of Bison antiquus by Palaeoindian groups, such as those associated with the Clovis culture [25] and the later Folsom tradition. [26] The Folsom tradition in particular is thought to have been reliant on hunting bison. [27]
One of the best educational sites to view in situ semifossilized skeletons of over 500 individuals of B. antiquus is the Hudson-Meng archeological site operated by the U.S. Forest Service, 18 mi (29 km) northwest of Crawford, Nebraska. A number of paleo-Indian spear and projectile points have been recovered in conjunction with the animal skeletons at the site, which is dated around 9,700 to 10,000 years ago. The reason for the "die-off" of so many animals in one compact location is still in conjecture; some professionals argue it was the result of a very successful paleo-Indian hunt, while others believe the herd died as a result of some dramatic natural event, to be later scavenged by humans. Individuals of B. antiquus of both sexes and a typical range of ages have been found at the site. [28] [29] [30]
B. antiquus may have been hunted by Clovis people in North and South Carolina, based on blood residue from Clovis points. [31] At Jake Bluff in northern Oklahoma, Clovis points are associated with numerous butchered Bison antiquus bones, which represented a bison herd of at least 22 individuals. At the time of deposition, the site was a steep-sided arroyo (dry watercourse) that formed a dead end, suggesting that hunters trapped the bison herd within the arroyo before killing them. [25] Other arroyo trap sites include Cooper in northwest Oklahoma and Badger Hole also in Oklahoma, which are associated with Folsom points. [32] [33] B. antiquus remains exhibiting butchery marks have been found at Ayer Pond on Orcas Island in Washington State. [34] [11]
The living American bison (Bison bison) is suggested to have evolved from Bison antiquus in central North America at the very end of the Pleistocene. The last populations of B. antiquus became extinct during the early Holocene, around 10,000 years ago. [23] Likely intermediates between the species are referred to as Bison "occidentalis" . [8]
The dire wolf is an extinct canine. The dire wolf lived in the Americas during the Late Pleistocene and Early Holocene epochs. The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized: Aenocyon dirus guildayi and Aenocyon dirus dirus. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles.
The Clovis culture is an archaeological culture from the Paleoindian period of North America, spanning around 13,050 to 12,750 years Before Present (BP). The type site is Blackwater Draw locality No. 1 near Clovis, New Mexico, where stone tools were found alongside the remains of Columbian mammoths in 1929. Clovis sites have been found across North America. The most distinctive part of the Clovis culture toolkit are Clovis points, which are projectile points with a fluted, lanceolate shape. Clovis points are typically large, sometimes exceeding 10 centimetres (3.9 in) in length. These points were multifunctional, also serving as cutting tools. Other stone tools used by the Clovis culture include knives, scrapers, and bifacial tools, with bone tools including beveled rods and shaft wrenches, with possible ivory points also being identified. Hides, wood, and natural fibers may also have been utilized, though no direct evidence of this has been preserved. Clovis artifacts are often found grouped together in caches where they had been stored for later retrieval, and over 20 Clovis caches have been identified.
Palaeoloxodon is an extinct genus of elephant. The genus originated in Africa during the Early Pleistocene, and expanded into Eurasia at the beginning of the Middle Pleistocene. The genus contains the largest known species of elephants, over 4 metres (13 ft) tall at the shoulders and over 13 tonnes (29,000 lb) in weight, representing among the largest land mammals ever, including the African Palaeoloxodon recki, the European straight-tusked elephant and the South Asian Palaeoloxodon namadicus. P. namadicus has been suggested to be the largest known land mammal by some authors based on extrapolation from fragmentary remains, though these estimates are highly speculative. In contrast, the genus also contains many species of dwarf elephants that evolved via insular dwarfism on islands in the Mediterranean, some like Palaeoloxodon falconeri less than 1 metre (3.3 ft) in shoulder height as fully grown adults, making them the smallest elephants known. The genus has a long and complex taxonomic history, and at various times, it has been considered to belong to Loxodonta or Elephas, but today is usually considered a valid and separate genus in its own right.
The steppe bison or steppe wisent is an extinct species of bison. It was widely distributed across the mammoth steppe, ranging from Western Europe to eastern Beringia in North America during the Late Pleistocene. It is ancestral to all North American bison, including ultimately modern American bison. Three chronological subspecies, Bison priscus priscus, Bison priscus mediator, and Bison priscus gigas, have been suggested.
The American lion, with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 130,000 to 12,800 years ago. Genetic evidence suggests that its closest living relative is the lion, with the American lion representing an offshoot from the lineage of the largely Eurasian cave lion, from which it is suggested to have split around 165,000 years ago. Its fossils have been found across North America, from Canada to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids to ever exist, and an important apex predator.
The Folsom tradition is a Paleo-Indian archaeological culture that occupied much of central North America from c. 10800 BCE to c. 10200 BCE. The term was first used in 1927 by Jesse Dade Figgins, director of the Denver Museum of Nature and Science. The discovery by archaeologists of projectile points in association with the bones of extinct Bison antiquus, especially at the Folsom site near Folsom, New Mexico, established much greater antiquity for human residence in the Americas than the previous scholarly opinion that humans in the Americas dated back only 3,000 years. The findings at the Folsom site have been called the "discovery that changed American archaeology."
The Columbian mammoth is an extinct species of mammoth that inhabited North America from southern Canada to Costa Rica during the Pleistocene epoch. The Columbian mammoth descended from Eurasian steppe mammoths that colonised North America during the Early Pleistocene around 1.5–1.3 million years ago, and later experienced hybridisation with the woolly mammoth lineage. The Columbian mammoth was among the last mammoth species, and the pygmy mammoths evolved from them on the Channel Islands of California. The closest extant relative of the Columbian and other mammoths is the Asian elephant.
The mammoth steppe, also known as steppe-tundra, was once the Earth's most extensive biome. During glacial periods in the later Pleistocene it stretched east-to-west, from the Iberian Peninsula in the west of Europe, then across Eurasia and through Beringia and into the Yukon in northwest Canada; from north-to-south, the steppe reached from the Arctic southward to southern Europe, Central Asia and northern China. The mammoth steppe was cold and dry, and relatively featureless, though climate, topography, and geography varied considerably throughout. Certain areas of the biome—such as coastal areas—had wetter and milder climates than others. Some areas featured rivers which, through erosion, naturally created gorges, gulleys, or small glens. The continual glacial recession and advancement over millennia contributed more to the formation of larger valleys and different geographical features. Overall, however, the steppe is known to be flat and expansive grassland. The vegetation was dominated by palatable, high-productivity grasses, herbs and willow shrubs.
Camelops is an extinct genus of camel that lived in North and Central America from the middle Pliocene to the end of the Pleistocene. It is more closely related to living camels than to lamines, making it a true camel of the Camelini tribe. Its name is derived from the Ancient Greek κάμηλος and ὄψ, i.e. "camel-face". Camelops lived across western North America, ranging from the Pacific Coast to the Great Plains, southwards to Honduras and northwards to Alaska. Camelops became extinct as part of the end-Pleistocene extinction event along with most large mammals across the Americas. The extinctions followed the arrival of humans to the Americas, and evidence has been found indicating that humans butchered Camelops, suggesting that hunting may have been a factor in its extinction.
The Chibanian, more widely known as the Middle Pleistocene, is an age in the international geologic timescale or a 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 0.770 Ma and 0.129 Ma, also expressed as 770–129 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Paleolithic over 300 ka.
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian. The beginning of the Late Pleistocene is the transition between the end of the Penultimate Glacial Period and the beginning of the Last Interglacial around 130,000 years ago. The Late Pleistocene ends with the termination of the Younger Dryas, some 11,700 years ago when the Holocene Epoch began.
The straight-tusked elephant is an extinct species of elephant that inhabited Europe and Western Asia during the Middle and Late Pleistocene. One of the largest known elephant species, mature fully grown bulls on average had a shoulder height of 4 metres (13 ft) and a weight of 13 tonnes (29,000 lb). Straight-tusked elephants likely lived very similarly to modern elephants, with herds of adult females and juveniles and solitary adult males. The species was primarily associated with temperate and Mediterranean woodland and forest habitats, flourishing during interglacial periods, when its range would extend across Europe as far north as Great Britain and Denmark and eastwards into Russia, while persisting in southern Europe during glacial periods. Skeletons found in association with stone tools and in once case, a wooden spear, suggest they were scavenged and hunted by early humans, including Homo heidelbergensis and their Neanderthal successors.
Bison latifrons, also known as the giant bison or long-horned bison, is an extinct species of bison that lived in North America during the Late Pleistocene epoch ranging from southern Canada to Mexico. It is noted for large body size and its distinctive long horns.
Hippopotamus antiquus is an extinct species of the genus Hippopotamus that ranged across Europe during the Early and Middle Pleistocene. It was considerably larger than the living hippopotamus.
Bison occidentalis is an extinct species of bison that lived in North America, from about 11,700 to 5,000 years ago, spanning the end of the Pleistocene to the mid-Holocene.
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna, which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by its extreme size bias towards large animals, and widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence. The timing and severity of the extinctions varied by region and are thought to have been driven by varying combinations of human and climatic factors. Human impact on megafauna populations is thought to have been driven by hunting ("overkill"), as well as possibly environmental alteration. The relative importance of human vs climatic factors in the extinctions has been the subject of long-running controversy.
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene. There are two recognized species: the lesser short-faced bear and the giant short-faced bear. Of these species, A. simus was larger, is known from more complete remains, and is considered one of the best known members of North America's extinct Ice Age megafauna. A. pristinus was largely restricted to the Early Pleistocene of the eastern United States, whereas A. simus had a broader range, with most finds being from the Late Pleistocene of the United States, Mexico and Canada. A. simus evolved from A. pristinus, but both species likely overlapped in the Middle Pleistocene. Both species are relatively rare in the fossil record.
St. Mary Reservoir is a reservoir in southwestern Alberta, Canada. It was created for irrigation purposes by the damming of the St. Mary River, which was completed in 1951. The Kainai Nation's Blood 148 Indian reserve borders its northwest side. There are camping and picnic areas at the reservoir, and it is a popular site for power boating, water skiing, windsurfing, swimming and fishing.
The narrow-nosed rhinoceros, also known as the steppe rhinoceros is an extinct species of rhinoceros belonging to the genus Stephanorhinus that lived in western Eurasia, including Europe, as well as North Africa during the Pleistocene. It first appeared in Europe around 500,000 years ago during the Middle Pleistocene and survived there until at least 34,000 years Before Present. It was native to temperate and Mediterranean environments, where it fed on low growing plants and to a lesser extent woody plants. Evidence has been found that it was exploited for food by archaic humans, including Neanderthals.
