El Fin del Mundo (Spanish: 'End of the World') is an ancient Pleistocene site in northwestern Sonora, Mexico. It features Clovis culture period occupation dating around 13,390 calibrated years BP. It was discovered during a 2007 survey.

The Pleistocene is the geological epoch which lasted from about 2,588,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations. 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.

Sonora State of Mexico

Sonora, officially Estado Libre y Soberano de Sonora, is one of 31 states that, with Mexico City, comprise the 32 federal entities of United Mexican States. It is divided into 72 municipalities; the capital city is Hermosillo. Sonora is bordered by the states of Chihuahua to the east, Baja California to the northwest and Sinaloa to the south. To the north, it shares the U.S.–Mexico border with the states of Arizona and New Mexico, and on the west has a significant share of the coastline of the Gulf of California.

Mexico country in the southern portion of North America

Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.

This is the oldest Clovis site in North America. There's also the Aubrey site in Denton County, Texas, [1] which produced a radiocarbon date that is almost identical. [2]

Denton County, Texas County in the United States

Denton County is a county in the U.S. state of Texas. As of the 2010 census, its population was 662,614, making it the ninth-most populous county in Texas. The county seat is Denton. The 2017 Census Bureau estimate for Denton County's population is 836,210. The county, which was named for John B. Denton, was established in 1846.

Clovis hunters

In 2011, remains of Gomphothere dating around 13,390 calibrated years BP were found here. This was the first time such an association was found in a northern part of the continent where gomphotheres had been thought to have gone extinct 30,000 years ago. [3] In July 2014, it was announced that the "position and proximity of Clovis weapon fragments relative to the gomphothere bones at the site suggest that humans did in fact kill the two animals there.

Gomphothere family of mammals

Gomphotheres are any members of the diverse, extinct taxonomic family Gomphotheriidae. Gomphotheres were elephant-like proboscideans, but not belonging to the family Elephantidae. They were widespread in North America during the Miocene and Pliocene epochs, 12–1.6 million years ago. Some lived in parts of Eurasia, Beringia, and following the Great American Interchange into South America. Beginning about 5 million years ago, they were gradually replaced by modern elephants, apart from the last two South American genera, of which Cuvieronius did not become extinct until 9,100 BP, and Haplomastodon, by some authors reclassified into Notiomastodon, fossils have been dated to as recently as 6,060 BP in the Valle del Magdalena, Colombia. These gomphotheres also survived in Mexico and Central America until the end of the Pleistocene.

Of the seven Clovis points found at the site, four were in place among the bones, including one with bone and teeth fragments above and below. The other three points had clearly eroded away from the bone bed and were found scattered nearby." [4]

Bones of horse and bison, as well as horse teeth were also found at the site.

Rockwall, Texas City in Texas, United States

Rockwall is a city in Rockwall County, Texas, United States, which is part of the Dallas/Fort Worth Metroplex. It is the county seat of Rockwall County. The population was 37,490 at the 2010 census. The name Rockwall is derived from a naturally jointed geological formation, which has the appearance of an artificial wall.

Clovis culture Prehistoric culture in the Americas

The Clovis culture is a prehistoric Paleo-Indian culture, named for distinct stone tools found in close association with Pleistocene fauna at Blackwater Locality No. 1 near Clovis, New Mexico, in the 1920s and 1930s. It appears around 11,500–11,000 uncalibrated radiocarbon years before present at the end of the last glacial period, and is characterized by the manufacture of "Clovis points" and distinctive bone and ivory tools. Archaeologists' most precise determinations at present suggest this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago. Clovis people are considered to be the ancestors of most of the indigenous cultures of the Americas.

Monte Verde archaeological site in southern Chile, located near Puerto Montt, which has been dated to as early as 18,500 BP (16,500 B.C.)

Monte Verde is an archaeological site in southern Chile, located near Puerto Montt, Southern Chile, which has been dated to as early as 18,500 cal BP. Previously, the widely accepted date for early occupation at Monte Verde was ~14,500 years cal BP. This dating added to the evidence showing that the human settlement of the Americas pre-dates the Clovis culture by roughly 1000 years. This contradicts the previously accepted "Clovis first" model which holds that settlement of the Americas began after 13,500 cal BP. The Monte Verde findings were initially dismissed by most of the scientific community, but the evidence then became more accepted in archaeological circles.

Paleo-Indians classification term given to the first peoples who entered the American continents

Paleo-Indians, Paleoindians or Paleoamericans is a classification term given by scholars to the first peoples who entered, and subsequently inhabited, the Americas during the final glacial episodes of the late Pleistocene period. The prefix "paleo-" comes from the Greek adjective palaios (παλαιός), meaning "old" or "ancient". The term "Paleo-Indians" applies specifically to the lithic period in the Western Hemisphere and is distinct from the term "Paleolithic".

Lewisville Lake

Lewisville Lake is a reservoir in North Texas (USA) on the Elm Fork of the Trinity River in Denton County near Lewisville. Originally engineered in 1927 as Lake Dallas, the reservoir was expanded in the 1940s and 1950s and renamed Lewisville Lake. It was built for flood control purposes and to serve as a water source for Dallas and its suburbs, but residents also use it for recreational purposes.

Columbian mammoth An extinct species of mammoth that inhabited North America

The Columbian mammoth is an extinct species of mammoth that inhabited North America as far north as the northern United States and as far south as Costa Rica during the Pleistocene epoch. It was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene. The Columbian mammoth evolved from the steppe mammoth, which entered North America from Asia about 1.5 million years ago. The pygmy mammoths of the Channel Islands of California evolved from Columbian mammoths. The closest extant relative of the Columbian and other mammoths is the Asian elephant.

The Page-Ladson archaeological and paleontological site (8JE591) is a deep sinkhole in the bed of the karstic Aucilla River that has stratified deposits of late Pleistocene and early Holocene animal bones and human artifacts. The site was the first pre-Clovis site discovered in southeastern North America; radiocarbon evidence suggest that the site date from 14,200 to 14,550 BP. These dates are roughly 1,000 to 1,500 years before the advent of the Clovis culture. Early dates for Page-Ladson challenge theories that humans quickly decimated large game populations in the area once they arrived.

<i>Cuvieronius</i> genus of mammals (fossil)

Cuvieronius is an extinct New World genus of gomphotheres and is named after the French naturalist Georges Cuvier. Alive, specimens typically stood about 2.3 m (7.5 ft) tall at the shoulder, weighed about 3.5 t and would have superficially resembled modern elephants with spiral-shaped tusks.

Buttermilk Creek Complex Place in Texas, United States

Buttermilk Creek Complex refers to the remains of a paleolithic settlement along the shores of Buttermilk Creek in present-day Salado, Texas dated to approximately 15,500 years old. If confirmed, the site represents evidence of human settlement in the Americas that pre-dates the Clovis culture.

Golondrina point

Golondrina points are lanceolate spear or dart projectile points, of medium size, dated to the transitional Paleo-Indian Period, between 9000–7000 BP. Golondrina points were attached on split-stem hafts and may have served to bring down medium-sized animals such as deer, as well as functioning as butchering knives. Distribution is widespread throughout most of Texas, and points have also been discovered in Arkansas and Mexico. The concentration of Golondrina specimens is highest across the South Texas Plains, where the point is the most prevalent of Paleo-Indian types and defines a distinctive cultural pattern for the region. The Golondrina point is so named for its flared basal corners ("ears"), which resemble a swallow's split tail. Classification of Golondrina can be difficult because of its similarity to other types, particularly the Plainview point, to which it was originally thought to be related.

Tibitó

Tibitó is the second-oldest dated archaeological site on the Altiplano Cundiboyacense, Colombia. The rock shelter is located in the municipality Tocancipá, Cundinamarca, Colombia, in the northern part of the Bogotá savanna. At Tibitó, bone and stone tools and carbon have been found. Bones from Haplomastodon, Cuvieronius, Cerdocyon and white tailed deer from the deepest human trace containing layer of the site is carbon dated to be 11,740 ± 110 years old. The oldest dated sediments are lacustrine clays from an ancient Pleistocene lake.

Sabana Formation

The Sabana Formation is a geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The formation consists mainly of shales with at the edges of the Bogotá savanna lignites and sandstones. The Sabana Formation dates to the Quaternary period; Middle to Late Pleistocene epoch, and has a maximum thickness of 320 metres (1,050 ft), varying greatly across the savanna. It is the uppermost formation of the lacustrine and fluvio-glacial sediments of paleolake Humboldt, that existed at the edge of the Eastern Hills until the latest Pleistocene.

Settlement of the Americas Prehistoric migration from Asia

The first settlement of the Americas began when Paleolithic hunter-gatherers first entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum. These populations expanded south of the Laurentide Ice Sheet and rapidly throughout both North and South America, by 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians.
