Cueva Fell or Fell'sCave is a natural cave and archaeological site in southern Patagonia. [1] Cueva Fell is in proximity to the Pali Aike Crater, another significant archaeological site. Cueva Fell combined with the nearby Pali Aike site have been submitted to UNESCO as a possible World Heritage Site. [2]
Fell's Cave was discovered by Junius Bird. It came to his attention because arrow points and flakes were found on the surface. The cave was originally called the Río Chico shelter, but was later renamed by Bird to Fell's Cave in honor of the Fell family who owned the Estancia Brazo Norte, the North Arm Station, where the cave is located. [3] Excavation of the site began in 1936.
Fell's Cave is located in the Río Chico canyon, Chile, near the Straits of Magellan and the Argentine border. This area is known as the Southern Patagonian Basalt Plateaus. [4] Situated on the southeast side of what was once a river bank, it is more accurately described as a rock shelter. It was formed by river water wearing away at the sandstone bank, leaving behind a canopy of lava conglomerate and thus creating a shelter 28 ft (8.5 m) deep and 38 ft (12 m) wide. The erosion formed a smooth floor of hard clay. [5] Remnants of sandstone still clinging to the conglomerate roof eventually fell to the floor, forming an archaeologically sterile layer that separated later human occupation periods. [5]
Junius Bird labelled the occupational sediment layers of the site from top to bottom, the top layer directly under the surface is I and the oldest, lowest layer is V.
The surface material of the site is composed of dirt, rocks, and hard-packed sheep manure. The surface layer ranges from 18 to 24 in (46 to 61 cm) in thickness. [3]
The youngest stratigraphic layer of Fell's Cave is a dark earth layer, reaching approximately 10 in (25 cm) in thickness. [6] This component dates from around 700 years BP to the present. [7] According to conventional radiocarbon dating, the layer dates to 1265 CE +-90. [8]
The division between Layer I and Layer II is relatively indistinguishable as the sediments are of similar dark earth, and also reach about 10 in (25 cm) or more in thickness. [6] This layer dates to around 6,500 years BP. [7]
This layer dates to around 8,500 to 6,500 years BP. [7] The earth consistency between Layers II and III marking a notable distinction between the two. Layer III is approximately 12 to 15 in (30 to 38 cm) thick and consists of compacted dark earth. [6]
The thickness of this layer varies from 13 to 17 in (33 to 43 cm) and consists of firmly packed dark earth. [9] This layer dates from c. 10,000 to 8,500 years BP. [7]
After the earliest layer, Layer V, had accumulated, sandstone slabs fell from the roof of the cave and sealed it off. This layer is 15 to 20 in (38 to 51 cm) thick. [5]
A refuse soft clay soil varying in thickness from 3 to 9 in (7.6 to 22.9 cm) composes the oldest occupation level at the site. [10] The site dates from 11,000 +-170 years BP to 10,080 +-160 years BP according to conventional radiocarbon dating. [8]
Bird named the periods from earliest to latest, thus Period I is the oldest and is associated with Layer V, while Period V is the latest and is associated with Layer I.
This period (layer I) is typified by a tool assemblage containing small arrow points and various bone tools, as well as such cultural materials as combs and beads. [7] Based on the style of the arrow points, it is likely that this period is associated with the Ona Indians. [7] The faunal assemblage of this period is dominated by guanaco bone fragments. [6]
Period IV is characterized by the presence of stone tools such as stemmed or legged stone points, knives, and small thumb-nail scrapers as well as a bone tool assemblage. [11] Large bolas, various beads and other ornaments are also present. [11] This Period can also be distinguished by the building of structures including extended burials and rock cairns. [11] Again, the faunal assemblage is dominated by guanaco. [9]
Present in this layer are bone awls, stone scrapers, and triangular stone points with rounded bases. Also, bolas of notably smaller size than the subsequent later period, period IV. [7] It has been suggested that these small stone bolas may have been used in procurement of birds. [7] Guanaco and fox bone fragments dominate the faunal assemblage. [6]
This layers consists mainly of bone points and awls, and stone scrapers. [7] Junius Bird notes in Travels and Archaeology in South Chile that this layer contained significantly more sediment in relation to artifact distribution. [9]
The oldest cultural occupation at this site belongs to the Fell's Tradition. [12] Thus, Fell's Cave is the type site for the Fell's Tradition. This tradition is characterized most notably by fishtail points as well as various stone scrapers, choppers, stone discs and bone tools. [7] Several hearths were also excavated from this level which produced three radiocarbon dates between c.11,000 and 10,000 years BP. [7]
In the Late Pleistocene, prior to 12,500 years BP, the area surrounding Cueva Fell was dominated by high winds, year-round freezing temperatures, and annual precipitation under 300 mm. This heathland environment was replaced by a treeless, xeric, herbaceous steppe environment through 11,000 years BP, as the freezing temperatures and winds began to abate. [13] [14] This is the climate and terrain that most closely predated the first human inhabitants in the area.
The earliest human occupation dates suggested by the finds in Layer V—c. 11,000 to 10,000 years BP correspond to a period of stadial cooling. In what has been described as a possible South American equivalent to the Younger Dryas, the Patagonian region experienced a period of low temperatures and high precipitation as well as advancing glaciers. [15] This was followed in 10,000 to 9,000 years BP by a warming trend. These two thousand years in question marked a fitful end to the last ice age, one marked by high environmental variability. While this produced significant changes in some taxa, humans, at this time, were already becoming adept at adjusting to new environments and appear not to have been deleteriously affected by the changeable and unpredictable climate. [16]
As the Holocene warming trend persisted, so the environment of southern Patagonia continued to change. The archaeology of Fell's Cave provides evidence for the regular occurrence of summer droughts in the area—droughts that, combined with increasing summer storm activity, may have led to wildfires. The decrease in water availability combined with the evident (through pollen analysis) dramatic change in grazing flora species, are proposed as contributing factors to the evident faunal extinction. [17] [18]
The period of 9,000 to 6,000 years BP saw less remarkable shifts in climate, with a general trend away from xeric taxa and, it is then presumed, an increase in precipitation. There is insufficient radiocarbon control at the site to determine local climate conditions post-6,000 years BP, however regional ecology suggests a slight shift towards more aridity. [19]
Today Cueva Fell joins most of southern Argentina in what is known as the Fuego-Patagonia steppe environment. The area receives less than 400 mm (16 in) annual precipitation (typical for the Patagonia region but much drier than neighbouring coastal or mountain terrains) and is dominated by bunch grasses from the genera Festuca and Stipa, along with a variety of herbaceous vegetation. [20]
Cueva Fell is notable for the range of now-extinct faunal finds excavated from within it. Notable among these are the giant sloth and the horse. The horse was to become extinct and absent in the Americas through most of the Holocene until it was imported by Europeans. [21] In fact the evidence of the ancient horse Cueva Fell was the first proof that horses occupied the Americas before being reintroduced from the Old World. The stratified remains of both human and animals provides evidence that human occupation of the area actually preceded the extinction of both the native horse (Hippidion saldiasi) and the ground sloth Mylodon . This same evidence suggested that ancient horse was hunted and eaten. [22] However humans weren't the sole predators in the area. Bone remains of the horse, llama and ground sloth all display puncture marks, most likely made by the Patagonia panther. [23]
The Early Holocene taxa change—the extinction of mostly herbivorous animals in South America—was initially attributed to human over-hunting, as were the megafaunal extinctions in North America. Analysis of pollen extracted from Cueva Fell suggested a substantial reduction in grassland in southern Patagonia in the period just preceding these extinctions, and was an early piece of evidence in the mounting argument against hunting as the primary cause of species collapse. [4] Large quantities of guanaco (lama) were also found in the older depositional layers. Where other large grazing fauna died out in the early Holocene, guanaco appear to have survived as a result of their less specialized plant diet, adapting to the change in vegetation that accompanied the warming Holocene. Guanaco population sizes initially dipped along with other grazing species, but eventually recovered. [24]
Analysis of canine remains found in all five human occupation levels of the cave initially suggested they were those of domestic dog (Canis familiaris). This would have been remarkable as the earliest evidence for the domestic dog in the Americas. However subsequent analyses suggest the skull and teeth remains to have been from two wild species: Pseudalopex griseus (South American gray fox) and Canis avus (a small fox or wolf-life canine, particular to South America in the late Pleistocene period). [25] Other faunal bone remains include hawks and falcons. [23]
The first excavation of Fell's cave in 1936 yielded 511 artefacts. These included hafted implements, knives, scrapers, bolas, a couple of circular rubbing stones, and bone tools. [26]

Perhaps the most significant find in the 1936 excavation was the fishtail projectile point. All of the fishtail points were associated with large mammals including: extinct horses, giant ground sloths, and guanacos. Fifteen fishtail projectile points were recovered from Layer V which is the oldest layer that dates back to 11,000 +-170 and 10,080 +-160 years BP. These fishtail point have been radiocarbon dated to be ca. 11,000 years old. [27]
Discoidal stones, referred in the chart as circular rubbing stones, were also found. Bird notes in a 1970 journal article that "stone artefacts shaped by pecking and grinding are so generally absent among Paleo-Indian finds that exceptions are noteworthy". [28] There were two stones found in Cueva Fell; both of them were clearly associated with animal remains. Both were made from lava. The larger stone has a diameter of about 12.3 cm (4.8 in) and weighs about 1.12 kg (2.5 lb) while the smaller stone is about 8.4 cm (3.3 in) in diameter and weighs about 0.5 kg (1.1 lb). [29] There was also a substantial amount of scrapers found throughout all the Cueva Fell layers. The bone tools found, according to Bird, were made from sloth bone because there bone used showed no evidence of marrow cavities. [30]
In 1969 there was a second dig organized at Cueva Fell but it was focused in a slightly different location of the cave. During this excavation 415 artifacts were found; various points, knives, scrapers, cores, bolas, and bone tools.

The colonization of the Americas may be one of the most contentious archaeological debates today. The issue involves a large body of research and numerous theories as to how and when this event began. For decades, the Clovis-first model [32] [33] trumped all other theories for the Settlement of the Americas. This theory basically holds that the Clovis culture constituted the earliest peoples to arrive in and inhabit North America. Entering the Americas from Asia via the Bering Land Bridge and migrating south through the ice free corridor, the Clovis people populated southern North America. This population spread through Central America and finally South America.
At the time the theory was proposed no archaeological evidence had been discovered in the Americas which pre-dated 11,050 to 10,800 years BP, or the onset of the Clovis culture. However, in the last few decades a multitude of sites were found, which at first challenged this theory and now demand a new model to explain the peopling of the Americas. [34] Based on the current understanding of archaeological evidence, it is now widely accepted that a pre-Clovis culture colonized the Americas via a Pacific coastal route sometime between 14,000 and 12,000 years BP. [35]
Some of the evidence supporting the coastal theory comes from the southernmost portions of South America. Many researchers now agree that occupation of Tierra del Fuego, between 11,000 and 10,500 years ago, simply does not provide enough time for mid-continental migration. A similar argument is made about Monte Verde, which may be the best known and most widely accepted of these sites and which pre-dates Clovis by approximately 1,000 years.
Although site discovery and excavation were not recent, Cueva Fell is representative of occupation of southern South America. The earliest occupation at Cueva Fell, between 11,000 +-170 and 10,080 +-160 years BP, does not pre-date but is coeval with Clovis. [36] Other Late Pleistocene sites in Argentina, such as Cerro Tres Tetas, Cueva Casa del Minero and Piedra Museo are also contemporaneous with Clovis and the early occupation at Fell's Cave. [34]
The common tendency to compare South American and North American prehistory is increasingly becoming outmoded, most notably in regards to early technological adaptations. It has been long believed that the early fluted points of South America represented a diffusion of the fluted North American Clovis points. South American fluted points include the fishtail point represented at Cueva Fell and many other regions, the El Jobo point (Venezuela), and the Paijan point (Peru and Ecuador), all of which dating to Clovis times. [37]
The fluted stone tool variants of South America represent regional adaptations to the procurement of Pleistocene megafauna that contrasts with the continent-wide use of Clovis points in North America. [38] Such regional technological adaptations seem to reflect the initial dispersal of small paleoindian groups throughout the vast continent. The fishtail points of Cueva Fell thus represent crucial evidence in the distinction between tool technologies in the southern and northern continents of the Americas.
Finally, Cueva Fell deserves recognition for representing possibly the earliest occupation of Fuego-Patagonia approximately 11,000 BP. [39] This southern region of South America is symbolic of "the end of the line" for the initial colonization of the New World.
The early inhabitants of Fuego-Patagonia signify sparse populations spread out over large territories and chances of site discovery in this region are low. [40] Compounding the low likelihood of site discovery in this region is the deeply buried contexts associated with such early occupation and the subsequent increase of various perturbation processes threatening the archaeological integrity. [40] Many of these sites, Cueva Fell included, are rock shelters which have been used as dens by carnivorous fauna over thousands of years, which not only disturb archaeological deposits but add difficulty to recognizing archaeological sites. [40] Low population density combined with these other factors make Junius Bird's discovery of Cueva Fell in 1936 truly remarkable in and of itself.
Clovis points are the characteristically fluted projectile points associated with the New World Clovis culture, a prehistoric Paleo-American culture. They are present in dense concentrations across much of North America and they are largely restricted to the north of South America. There are slight differences in points found in the Eastern United States bringing them to sometimes be called "Clovis-like". Clovis points date to the Early Paleoindian period, with all known points dating from roughly 13,400–12,700 years ago. As an example, Clovis remains at the Murry Springs Site date to around 12,900 calendar years ago. Clovis fluted points are named after the city of Clovis, New Mexico, where examples were first found in 1929 by Ridgely Whiteman.
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.
Monte Verde is a Paleolithic archaeological site in the Llanquihue Province in southern Chile, located near Puerto Montt, Los Lagos Region. The site is primarily known for Monte Verde II, dating to approximately 14,550–14,500 calibrated years Before Present (BP). The Monte Verde II site has been considered key evidence showing that the human settlement of the Americas pre-dates the Clovis culture by at least 1,000 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. The site also contains an older, much more controversial layer suggested to date to 18,500 cal BP, that lacks the general acceptance of Monte Verde II.
Paleo-Indians were the first peoples who entered and subsequently inhabited the Americas towards the end of the Late Pleistocene period. The prefix paleo- comes from the Ancient Greek adjective: παλαιός, romanized: palaiós, lit. 'old; ancient'. The term Paleo-Indians applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic.
In the sequence of cultural stages first proposed for the archaeology of the Americas by Gordon Willey and Philip Phillips in 1958, the Lithic stage was the earliest period of human occupation in the Americas, as post-glacial hunter gatherers spread through the Americas. The stage derived its name from the first appearance of Lithic flaked stone tools. The term Paleo-Indian is an alternative, generally indicating much the same period.
Cueva de las Manos is a cave and complex of rock art sites in the province of Santa Cruz, Argentina, 163 km (101 mi) south of the town of Perito Moreno. It is named for the hundreds of paintings of hands stenciled, in multiple collages, on the rock walls. The art was created in several waves between 7,300 BC and 700 AD, during the Archaic period of pre-Columbian South America. The age of the paintings was calculated from the remains of bone pipes used for spraying the paint on the wall of the cave to create the artwork, radiocarbon dating of the artwork, and stratigraphic dating.
Piki Mach'ay is an archaeological site in the Ayacucho Valley of Peru. Radiocarbon dating from this cave indicates a human presence ranging from 22,200 to 14,700 years ago, but this evidence has been disputed and a more conservative date of 12,000 years BCE seems possible.
Toquepala Caves are located near Toquepala mine, about 154 km (96 mi) from the city of Tacna, in the extreme southeast of Peru. They are notable for a number of rock paintings. The best known of them is the cave named Abrigo del Diablo.
The Pali-Aike National Park is a park located in the Magallanes Region of Patagonia in Chile. Pali-Aike is a Tehuelche name that means Desolate Place. Created in 1970, it covers an area of 5,030 hectares and includes part of the Pali-Aike Volcanic Field. The park draws its name from a prominent volcanic cone known as the Pali Aike Crater.
The Big Eddy Site (23CE426) is an archaeological site located in Cedar County, Missouri, which was first excavated in 1997 and is now threatened due to erosion by the Sac River.
Devil's Lair is a single-chamber cave with a floor area of around 200 m2 (2,200 sq ft) that formed in a Quaternary dune limestone of the Leeuwin–Naturaliste Ridge, 5 km (3.1 mi) from the modern coastline of Western Australia. The stratigraphic sequence in the cave floor deposit consists of 660 cm (260 in) of sandy sediments, with more than 100 distinct layers, intercalated with flowstone and other indurated deposits. Excavations have been made in several areas of the cave floor. Since 1973, excavations have been concentrated in the middle of the cave, where 10 trenches have been dug. Archaeological evidence for intermittent human occupation extends down about 350 cm (140 in) to layer 30, with hearths, bone, and stone artefacts found throughout. The site provides evidence of human habitation of Southwest Australia 50,000 years before the present day.
Pedra Furada is an important collection of over 800 archaeological sites in the state of Piauí, Brazil. These include hundreds of rock paintings dating from circa 12,000 years before present. More importantly, charcoal from very ancient fires and stone shards that may be interpreted as tools found at the location were dated from 48,000 to 32,000 years before present, suggesting the possibility of a human presence tens of thousand of years prior to the arrival of the Clovis people in North America.
Pendejo Cave is a geological feature and archaeological site located in southern New Mexico about 20 miles east of Orogrande. Archaeologist Richard S. MacNeish claimed that human occupation of the cave pre-dates by tens of thousands of years the Clovis Culture, traditionally believed to be one of the oldest if not the oldest culture in the Americas.
Howieson's Poort Shelter is a small rock shelter in South Africa containing the archaeological site from which the Howiesons Poort period in the Middle Stone Age gets its name. This period lasted around 5,000 years, between roughly 65,800 BP and 59,500 BP. This period is important as it, together with the Stillbay period 7,000 years earlier, provides the first evidence of human symbolism and technological skills that were later to appear in the Upper Paleolithic.
Huaca Prieta is the site of a prehistoric settlement beside the Pacific Ocean in the Chicama Valley, just north of Trujillo, La Libertad Province, Peru. It is a part of the El Brujo Archaeological Complex, which also includes Moche (culture) sites.
The Andean preceramic refers to the early period of human occupation in the Andean area of South America that preceded the introduction of ceramics. This period is also called pre-ceramic or aceramic.
Elands Bay Cave is located near the mouth of the Verlorenvlei estuary on the Atlantic coast of South Africa's Western Cape Province. The climate has continuously become drier since the habitation of hunter-gatherers in the Later Pleistocene. The archaeological remains recovered from previous excavations at Elands Bay Cave have been studied to help answer questions regarding the relationship of people and their landscape, the role of climate change that could have determined or influenced subsistence changes, and the impact of pastoralism and agriculture on hunter-gatherer communities.
The coastal migration hypothesis is one of two leading hypotheses about the settlement of the Americas at the time of the Last Glacial Maximum. It proposes one or more migration routes involving watercraft, via the Kurile island chain, along the coast of Beringia and the archipelagos off the Alaskan-British Columbian coast, continuing down the coast to Central and South America. The alternative is the hypothesis solely by interior routes, which assumes migration along an ice-free corridor between the Laurentide and Cordilleran ice sheets during the Last Glacial Maximum.
Fishtail points, also known as Fell points are a style of Paleoindian projectile point widespread across much of South America at the end of the Late Pleistocene, around 13-12,000 years ago. They are thought to have been mutlifunctional, serving as cutting tools, as well as hafted to spears to use as hunting weapons, possibly in combination with spear throwers.
The theory known as "Clovis First" was the predominant hypothesis among archaeologists in the second half of the 20th century to explain the peopling of the Americas. According to Clovis First, the people associated with the Clovis culture were the first inhabitants of the Americas. This hypothesis came to be challenged by ongoing studies that suggest pre-Clovis human occupation of the Americas. In 2011, following the excavation of an occupation site at Buttermilk Creek, Texas, a group of scientists identified the existence "of an occupation older than Clovis." At the site in Buttermilk, archaeologists discovered evidence of hunter-gatherer group living and the making of projectile spear points, blades, choppers, and other stone tools. The tools found were made from a local chert and could be dated back to as early as 15,000 years ago.
