The cave acknowledged as Cova Gran (Avellanes-Santa Linya, Noguera) preserves a great number of vestiges in its sediments, which will allow researchers to reconstruct more than 50,000 several years of record of those people residing in the Pre-Pyrennean area (Lleida province), from the Neanderthals to the the to start with Homo sapiens as well as the hunther-gatherer-life style to the very first farmers and herders.

The investigate staff at the Centre for the Review of Archaeological Heritage of the Universitat Autònoma de Barcelona (CEPARQ-UAB) learning the Cova Gran considering the fact that 2002 has identified remains courting back from 45,000 to 4,000 yrs back. But no bones of people residing there had at any time been discovered. Until very last year’s dig marketing campaign, in which the skeletal continues to be of a human, in partial anatomic relationship, had been located two meters down below floor in a lateral excavation space. A locale in which scientists would not have imagined locating these forms of stays.

The established ofrecovered continues to be, which has been produced public today, corresponds to a female who has been specified the name of “Linya, the woman from Noguera”. The bones contain two femurs, one of them related to the pelvis, as effectively as the very long bones of the higher extremities (hummerus, radius/cubitus) and reduce extremities (tibia and fibula), the metapodia and a number of phalanges. The skull and axial skeleton (vertebrates and ribs), despite the fact that present, experienced minor illustration.

The relationship of the stratum in which the remains have been observed and the courting of a person of the bones have narrowed down the period in which she lived to all around 14,350 and 14,100 several years ago, which corresponds to the stop of the Higher Paleolithic time period, which also corresponds to the end of the Pleistocene.

“The stays of Linya open up a new doorway that brings us closer to discovering the conditions in which she died, but also information about her existence and that of individuals she lived with in the location. And at the exact same time, she is a essential determine in studying about the anatomy and genetic heritage of hunter-gatherer societies at the close of the Pleistocene in the northeastern section of the Iberian Peninsula”, highlights Rafael Mora, Chair Professor at the UAB Office of Prehistory and researcher at the CEPARQ. “The blend of distinct paleoanthropological, forensic, genomic and archaeological analyses currently underway will provide indicators which will enrich and rectify the present-day viewpoint of a discovery we only have preliminary details on thanks to the digs we are conducting”.

The point out of conservation of the bones has manufactured it needed to apply stabilizing and preservation processes in sights of potential research. These procedures are getting executed now at the Catalan Institute of Human Paleoecology and Social Evolution (IPHES).

Put in a all-natural receptacle

The stays were being found in just what is regarded as to be a natural receptacle, delimited by different blocks of substantial proportions fallen from the rockshelter. Researchers are at this time investigating no matter whether the extremities were moved toward the cubicle, even though the axial skeleton and skull were being protected under these big rocks. What researchers have been ready to determine is that the area is exactly where the individual was lain after she was lifeless. In accordance to the position of the femurs, she was lain right on the ground in a supine place. The to start with paleoanthropological characterization conducted suggests that the pelvic girdle corresponds to an grownup feminine, probably of smaller stature.

The skeleton appeared at the foundation of an archaeological sequencing of 7 consecutive archaeological levels that contains an abundance of lithic equipment,faunal and carbon remains, all of which issue to the use of the site as a residing house. But the bed on which the human body was lain did not have any of individuals components. Now, the investigate group is seeking for feasible funerary choices, which had been extremely typical in the burials of Homo sapiens. The sediment of the house marked out by the huge blocks is now remaining sampled to recover micro residue that could point out that the body was protected with animal skins or plant fibers. This would justify the way the overall body was lain on the floor, without the need of the need to have of digging a burial place.

“We are mindful of the require to be cautious when affirming that this is an intended burial site”, researcher at the CEPARQ Jorge Martinez-Moreno points out. He goes on to say that, “mortuary tactics between hunter-gatherers point to distinct options, ranging from an intentional burial to a secondary burial, the burial of portion of the entire body, cannibalism, or an accidental dying. We will want to evaluate these situations depending on the results of what we dig up in the region in which these continues to be appeared”.

Carbon-14 dating making use of fragments of the carbon discovered in the archaeological concentrations in which the remains appeared show that the sediment was fashioned in significantly less than a millennium, from around 14,400 to 13,500 years ago. The clarification for why this sediment grew so a great deal, and which was accompanied by the detachment of many significant blocks from the cave’s cornice, is remaining analyzed through the geomorphology and content that make up this aspect of the mountain’s slope.

A second of ecological change

The time time period in which Linya and her people lived was critical in climatic phrases. Some 14,700 years back, the world’s exceptionally chilly and severe local climate ailments attribute of the Last Glacial Greatest (close to 30,000 to 15,000 several years back) suddenly transformed and in a period of time of much less than 100 yrs, transformed into a new climate routine very similar to the a person present now. This function, recognised as the Bölling/Allerød warming, occurring some 14,700 to 12,900 a long time in advance of the present, and was characterised by a rise in temperatures and rainfall, which manufactured related ecological alterations.

Inspite of the fact that the effect of this event on the Pre-Pyrennees is not tremendously acknowledged, some indicators recovered at the Cova Gran have authorized scientists to analyze this incident. Carbon dating analysis signifies that the human species living there throughout the Very last Glacial Most only made use of European red pine (Pynus sylvestris) timber for fuel. In the sequence now remaining dug, in which the stays of Linya have been discovered, other new taxon’s in addition to red pine carbon have been determined, such the popular juniper (Juniperus), cherry trees (Prunus) and buckthorn (Rhamus catharticus/saxatilis), a set of trees and shrubs belonging to milder climates, unique to the harshness of the forests of the Past Glacial Greatest.

Pretty few stays of Homo sapiens in the Iberian Peninsula

The amount of money of human continues to be found in the Iberian Peninsula and corresponding to the Upper Paleolithic period (20,000 to 12,000 decades back) is scarce. In this feeling, the Cova Gran will be essential to understanding a lot more about their anatomy and the place the Hunter-gatherer societies came from at the conclude of the Pleistocene.

A modern paleogenetic analyze carried out by the Max Planck Institute on remains recovered from the El Mirón Cave in Santander and the Balma Guilanyà rock shelter in Lleida signifies that the genome sequencing of the “Red Woman of El Mirón”, relationship back 20,000 decades, reveals near ties to human populations of Western Europe. A situation which variations in the remains observed at the Balma Guilanyà rock shelter, courting 1,000 a long time afterwards than the remains observed at the Cova Gran, in which there is a continuation of genetic markers common to European populations, but also new markers which are present in the populations of the Italian Peninsula.

For that reason, in the interval of 20,000 to 13,000 several years, the genome of Pyrenean populations registers contacts with populations from the Mediterranean. “Maybe the new local weather circumstances of the Bölling/Allerød warming facilitated standard contacts involving these geographic parts?” scientists speculate. “The human remains at the Cova Gran will be critical to analyzing the solidity of this intriguing intuition”, they position out.

The CEPARQ workforce is convinced that the unforeseen discovery of Linya will assist to modulate the notions now sustained of the anatomy of those Homo sapiens, “of whom we have much less precise expertise than we do of Neanderthals”, scientists point out. They also point out the fact that “the will cause foremost to the appearance of a house made by massive blocks will assist us in studying about the behavior and choices taken by people people about a transcendental and popular party this sort of as demise: what ritual was followed by these people today who are element of our collective, but are no for a longer period current? The continues to be of Linya now pose several challenges, and we hope to remedy them in the coming years”, they conclude.

The archaeological worth of the Cova Gran de Santa Linya

The Cova Gran de Santa Linya, found in 2002, is a website measuring around 2,500 sq. meters, regarded as crucial to the study of the existence of human beings in the northeastern Iberian Peninsula.

It is 1 of the number of web sites of the Mediterranean location in which vestiges of a moment of “transition” have been discovered, such as those people of the previous Neanderthals (around 45,000 decades ago) and the visual appearance of contemporary people (some 37,000 to 30,000 years), their survival throughout the Last Glacial Optimum (20,000 to 15,000 several years), and the physical appearance of the first farmers and herders (7,000 to 4,000 a long time in the past).

The investigate carried out by the CEPARQ-UAB team at the Cova Gran de Santa Linya contains the money help of the Spanish Ministry for Science and Innovation, the Archaeology and Palaecology Provider of the Ministry for Tradition of the Government of Catalonia, the Institute for Lleida Scientific tests (IEI) of the Lleida Provincial Council, the Palarq Basis, the Leakey Basis and the City Council of Les Avellanes i Santa Linya.
