There are many common themes throughout the many different places that the paintings have been found; implying the universality of purpose and similarity of the impulses that might have created the imagery. Various conjectures have been made as to the meaning these paintings had to the people who made them. Prehistoric men may have painted animals to “catch” their soul or spirit in order to hunt them more easily, or the paintings may represent an animistic vision and homage to surrounding nature, or they may be the result of a basic need of expression that is innate to human beings, or they may be recordings of the life experiences of the artists and related stories from the members of their circle. While we may not fully understand the purpose for these paintings, we can appreciate and enjoy their beauty , admiring the creativity of those from long-ago eras. Technique A rock painting of a turtle in what is known as X-ray style—with some internal organs. Cave paintings are a form of Rock art , falling under the category of pictograph , or the application of pigments to a rock surface. Survival of ancient cave paintings is attributable to use of mineral pigments, most commonly manganese , hematite , malachite , gypsum , limonite, clays , and various oxides. The best preserved pictography is found under sheltering overhangs and in caves.
READ MORE History of archaeology No doubt there have always been people who were interested in the material remains of the past, but archaeology as a discipline has its earliest origins in 15th- and 16th-century Europe , when the Renaissance Humanists looked back upon the glories of Greece and Rome. Popes, cardinals, and noblemen in Italy in the 16th century began to collect antiquities and to sponsor excavations to find more works of ancient art.
These collectors were imitated by others in northern Europe who were similarly interested in antique culture. All this activity, however, was still not archaeology in the strict sense. It was more like what would be called art collecting today.

Academic Institution Partnership Hydrogeological Survey of Somalia Despite groundwater being the main source of water for humans, agriculture and livestock, there is neither a hydrogeological map nor a sound policy for groundwater management and exploration in Somalia. SWALIM undertook a quantitative and updated assessment of the groundwater resources of Somaliland and Puntland and the set-up of a system for groundwater level monitoring.

SWALIM project has developed systems for monitoring surface and groundwater in Somalia to support planning, development and sustainable exploitation of the scarce and valuable water resources in the country. SWALIM seeks to strengthen these three dimensions together in order to put in place a viable capability for sustainable water and land resource management within Somali institutions.
Up-to-date Information about these resources ensures informed decisions on their management and utilization, subsequently guaranteeing they will remain for the welfare of future generations. Information extracted from satellite images are essential for informed land planning, consistent natural resources assessment, disaster early warning and management, and other tasks.
The term “Clovis” comes from Clovis, New Mexico, where it names both an archaeological site and a fluted projectile point style. Many projectile points are named as it is much easier to remember what an “Elko-Eared” point looks like rather than something like “Point Type 2J. The term “prehistoric” has been misused and often has been stereotyped into an image of the brutal “cave man. All humans share a “prehistory.
Pottery in archaeology Introduction. The following is a basic introduction to pottery in archaeology, focusing particularly on the ceramics of the medieval period.
Rehydroxylation dating – for dating ceramic materials  Relative methods Relative or indirect methods tend to use associations built from the archaeological body of knowledge. An example is seriation , which may use the known style of artefacts such as stone tools or pottery. Ultimately, relative dating relies on tying into absolute dating with reference to the present. One example of this is dendrochronology which uses a process of tying floating chronologies of tree rings together by cross referencing a body of work.
In practice several different dating techniques must be applied in some circumstances, thus dating evidence for much of an archaeological sequence recorded during excavation requires matching information from known absolute or some associated steps, with a careful study of stratigraphic relationships. This polarity is stored within rocks; through this the rock can be dated. In a sedimentary sequence the associated material within the ash layer can be dated, giving a date for the eruption.
If this ash is found anywhere else in the world, a date will already be known bearing in mind transportation time. Stratigraphic relationships Archaeologists investigating a site may wish to date the activity rather than artifacts on site by dating the individual contexts which represents events. Some degree of dating objects by their position in the sequence can be made with known datable elements of the archaeological record or other assumed datable contexts deduced by a regressive form of relative dating which in turn can fix events represented by contexts to some range in time.
For example, the date of formation of a context which is totally sealed between two datable layers will fall between the dates of the two layers sealing it. However the date of contexts often fall in a range of possibilities so using them to date others is not a straightforward process.
A seafarers tale – an archaeological elucidation of a shipwreck By Sten Sjostrand Dreary weather and intermittent rain has led to a dramatic drop in temperature over the last few days and then, just as the rain finally stopped, a cold wind began to blow from the north. It whipped up high waves and enormous swells that broke repeatedly against the side of the ship giving the deck, and everyone on it, a good showering.
It was unbearably cold, wet and miserable.
The various dating techniques available to archaeologists by Michael G. Lamoureux, March/April Introduction. Today’s archaeologist has a wide variety of natural, electro-magnetic, chemical, and radio-metric dating methodologies available to her that can be used to accurately date objects that are just a few hundred years old as well as objects that are a few million years old with high.
During this stage, man colonized the New World and Australia. The main Palaeolithic cultures of Europe were, in chronological order: The term was introduced in by John Lubbock in Prehistoric Times”. The Palaeolithic was originally defined by the use of chipped stone tools but later an economic criterion was added and the practice of hunting and gathering is now regarded as a defining characteristic.
A term referring to an artifact in the form of a ring, but with a small break at one point, used particularly for forms of brooch and torc. It means not a complete ring”. The penannular brooch was characteristic of Irish production; generally of great size and probably worn on the shoulder with the pin pointing upward it was decorated with interlaced patterns. It was the most common type of dress fastener of the sub- Roman period ; it remained popular in Celtic regions of Britain up until the 10th century.
There is an extensive typology for these ornaments and they vary in appearance from plain bronze or iron rings to elaborately inlaid and gilded examples such as the Tara brooch which was made around AD in Ireland. British scholar and pioneer in archaeological excavation and recording, working on prehistoric and Romano-British sites in England.
His large-scale excavations unearthed villages, camps, cemeteries, and barrows at sites such as Woodcutts, Rotherley, South Lodge, Bokerly Dyke, and Wansdyke. From his study of firearms, he realized that something analogous to evolution can be traced in artifacts as well as in living organisms, with the same gradual developments and occasional degenerations. He assembled an ethnographical collection arranged by use rather than by provenance, a practical example of typology.
Radiocarbon Dating and Archaeology Radiocarbon dating has enriched archaeology, anthropology, and many other disciplines. The radiocarbon dating process starts with measuring Carbon , a weakly radioactive isotope of Carbon, followed by calibration of radiocarbon age results to calendar years. The sample-context relationship must be established prior to carbon dating.
The dating guidelines found on these Dating Pages (and the entire website) do not always work well with what the author calls “specialty” bottles (click for more information). This is because certain classes of these bottles were often made using glassmaking techniques from earlier times or with methods not used for utilitarian ware.
Cement board is used as a tile backer or a backer board for stucco applications on buildings. Augustine Taylor, building St. Mary’s church in Chicago in that year and was the dominant framing material in the U. Our photo left shows the interior of a modern platform-framed structure going up in Minneapolis, MN in The appeal of dimensional lumber was the reduced time and effort to construct a wood frame building compared with hewn timber frame beams that had to be cut and shaped, air dried for two years, and joined with mortise and tenon joints that required more highly skilled carpenters.
Initially church members were concerned that their building was being built of flimsy too-small sticks and scaffolding materials. But 2×4 and other dimensional lumber did not remain exactly the same physical size as its nominal size, and by or earlier the finished size of most framing lumber products was notably less than the nominal size. The table given below is of general interest in understanding the most-widely-used framing lumber species in North America up to about
Dating techniques Photo by: Bastos Dating techniques are procedures used by scientists to determine the age of an object or a series of events. The two main types of dating methods are relative and absolute.
The mass of the stone point, according to Perkins, is a integral part of the spear’s acceleration, causing the back of the dart to travel faster than the front, thereby compressing it like a spring. To Perkins, the stone point is more essential for the mechanics of the system than it is for tearing through the flesh of the animals it is meant to kill.

History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past. Historians can tell what cultures thrived in different regions and when they disintegrated. Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings. Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.
It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself. Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology , archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.
Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology.
It is based on changes in artifact assemblages or artifact stylistic attributes: In the example below, stylistic variation in glass bottles is illustrated. Note that the width of the curves represents the relative frequency or abundance of each bottle type during a given time interval.
Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using.
Usually in intimate association with these hooked implements of antler were found, in nearly every instance where the hooked implements were present, as exactly described later in this report, other objects, some of antler most of which were made from the base of the horn , some of stone Hereafter in this report, for convenience and not because we are fully convinced they are such, we shall designate the hooked implements as needles and the objects found with them as sizers.
We were aware that we had to face two probable objections in connection with our determination, namely, the orifices in the ends of the needles, and the perforations in the sizers, neither of which seem absolutely necessary for the use to which the needles and sizers were assigned. These are the findings which piqued Webb’s curiosity about the hooked antler implements and bannerstones. Webb “From a careful study of this body of artifacts, their position in the graves, and their association with each other, the conviction has grown that all of these antler hooks are the distal ends of atlatls.
All of the antler sections are handles, attached to the proximal end of the atlatl, and the “banner” stones, subrectangular bars, and composit shell artifacts are all atatl weights. While looking at his collection of bannerstones I mentioned that I had read somewhere of them being used as altatl weights. His response was that atlatls had been found in caves in the Southwest but not in the East, so there was no evidence of this.
Little did I realize at that time that a definitive study of their use as weights had been published 20 years previously by William S, Webb of the University of Kentucky. The in-situ finds of atlatl handles, weights and hooks left little doubt of their aboriginal use. The first excavation at the site was by Clarence B.
