Cave Of Salemas
The Cave of Salemas is located close to the village of Lousa in the municipality of Loures in the Lisbon District of Portugal. Discovered by archaeologists during the 1950s, the cave appears to have been occupied by humans as a temporary refuge during the Upper Paleolithic and used as a tomb during the Neolithic. Located in a Cretaceous limestone outcrop, the cave is situated about 100 metres north of the Neolithic dolmen known as the Anta do Alto da Toupeira. It is a solutional cave and consists of a winding rift passage about 30 metres long and one metre wide. Although not unique in the area, it is the most developed cave, both in terms of size and depth. It was first explored in September 1959 by L. Albuquerque e Castro and then fully excavated by a team from the Geological Survey of Portugal, headed by O. de Veiga Ferreira, José Camarate Andrade França and Georges Zbyszewski, during two digs in November 1959 and in October- December 1960. The top levels excavated contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loures
Loures () is a city and a municipality in Portugal which is part of the Lisbon District, District and Lisbon Metropolitan Area, Metropolitan area of Lisbon. It is the fifth most populous municipality in the country, with a total population of 201,632. History There was early human settlement in the Loures area dating back to the Upper Paleolithic period, as evidenced by findings at the Cave of Pego do Diabo and the Cave of Salemas. Several Neolithic burial chambers have been identified, such as the Anta de Carcavelos and the Anta do Alto da Toupeira. Loures was a Roman settlement during the 1st millennium, based in a cemetery that eventually became the site of the first church. It was also a region notable for the presence of many Castro culture, castros, before the Roman occupation; the Romans influenced many of these settlers to abandon the foothills and begin occupying the fertile lowlands for economic reasons. After the Romans, the Visigoths began occupying the territory, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solutrean
The Solutrean industry is a relatively advanced flint tool-making style of the Upper Paleolithic of the Final Gravettian, from around 22,000 to 17,000 BP. Solutrean sites have been found in modern-day France, Spain and Portugal. Details The term ''Solutrean'' comes from the type-site of " Cros du Charnier", dating to around 21,000 years ago and located at Solutré, in east-central France near Mâcon. The Rock of Solutré site was discovered in 1866 by the French geologist and paleontologist Henry Testot-Ferry. It is now preserved as the Parc archéologique et botanique de Solutré. The industry was named by Gabriel de Mortillet to describe the second stage of his system of cave chronology, following the Mousterian, and he considered it synchronous with the third division of the Quaternary period. The era's finds include tools, ornamental beads, and bone pins as well as prehistoric art. Solutrean tool-making employed techniques not seen before and not rediscov ...

Prehistoric Sites In Portugal
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 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 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Portugal
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as '' speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgan ...

Carbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Hyena
Hyenas, or hyaenas (from Ancient Greek , ), are feliform carnivoran mammals of the family Hyaenidae . With only four extant species (each in its own genus), it is the fifth-smallest family in the Carnivora and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems. Although phylogenetically closer to felines and viverrids, as part of suborder Feliformia, hyenas are behaviourally and morphologically similar to canids in several elements due to convergent evolution; both hyenas and canines are non-arboreal, cursorial hunters that catch prey with their teeth rather than claws. Both eat food quickly and may store it, and their calloused feet with large, blunt, nonretractable claws are adapted for running and making sharp turns. However, hyenas' grooming, scent marking, defecation habits, mating and parental behavior are consistent with the behavior of other feliforms. Hyenas feature prominently ...

Iberian Lynx
The Iberian lynx (''Lynx pardinus'') is a wild cat species endemic to the Iberian Peninsula in southwestern Europe. It is listed as Endangered on the IUCN Red List. In the 20th century, the Iberian lynx population had declined because of overhunting, poaching, fragmentation of suitable habitats, and the population decline of its main prey species, the European rabbit (''Oryctolagus cuniculus''), caused by myxomatosis and rabbit haemorrhagic disease. By the turn of the 21st century, the Iberian lynx was on the verge of extinction, as only 94 individuals survived in two isolated subpopulations in Andalusia in 2002. Conservation measures have been implemented since then, which included improving habitat, restocking of rabbits, translocating, reintroducing and monitoring Iberian lynxes. By 2012, the population had increased to 326 individuals, to 855 in 2020, and to 1,111 in 2021. It is a monotypic species, and is thought to have evolved from '' Lynx issiodorensis''. Taxonomy ...

Leopard
The leopard (''Panthera pardus'') is one of the five extant species in the genus '' Panthera'', a member of the cat family, Felidae. It occurs in a wide range in sub-Saharan Africa, in some parts of Western and Central Asia, Southern Russia, and on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. The leopard is considered locally extinct in Hong Kong, Singapore, South Korea, Jordan, Morocco, Togo, the United Arab Emirates, Uzbekistan, Lebanon, Mauritania, Kuwait, Syria, Libya, Tunisia and most likely in North Korea, Gambia, Laos, Lesotho, Tajikistan, Vietnam and Israel. Contemporary records suggest that the leopard occurs in only 25% of its historical global range. Compared to other wild cats, the leopard has relatively short legs and a long body with a large skull. Its fur is marked with rosett ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Bear
The cave bear (''Ursus spelaeus'') is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word "cave" and the scientific name ''spelaeus'' are used because fossils of this species were mostly found in caves. This reflects the views of experts that cave bears may have spent more time in caves than the brown bear, which uses caves only for hibernation. Taxonomy Cave bear skeletons were first described in 1774 by Johann Friedrich Esper, in his book ''Newly Discovered Zoolites of Unknown Four Footed Animals''. While scientists at the time considered that the skeletons could belong to apes, canids, felids, or even dragons or unicorns, Esper postulated that they actually belonged to polar bears. Twenty years later, Johann Christian Rosenmüller, an anatomist at Leipzig University, gave the species its binomial name. The bones were so numerous that most researcher ...

Brown Bear
The brown bear (''Ursus arctos'') is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the Order (biology), order Carnivora, rivaled in size only by its closest relative, the polar bear (''Ursus maritimus''), which is much less variable in size and slightly bigger on average. The brown bear's range includes parts of Russia, Central Asia, the Himalayas, China, Canada, the United States, Hokkaido, Scandinavia, Finland, the Balkans, the Picos de Europa and the Carpathian region (especially Romania), Iran, Anatolia, and the Caucasus. The brown bear is recognized as a national and state animal in several European countries. While the brown bear's range has shrunk, and it has faced local extinctions across its wide range, it remains listed as a least con ...

Stone Tool
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric (particularly Stone Age) cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture. Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, hand axes, and querns. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a flintknapper. Knapped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a process known as lithic reduction. One simple form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
