Archaeological Dating: Stratigraphy and Seriation

In this part of the class we go back in time to follow the branch of the tree of life that leads to us. In the previous sections, we compared and contrasted ourselves to other vertebrates, then to other mammals, then to primates, and mostly to hominoids apes. In paleoanthropology we start from the split that separates apes from humans and continue on that branch, and all its side branches, until we get to us. Paleoanthropology deals with hominids bipedal hominoids. In previous sections, we compared ourselves to living creatures that you can see running around in their natural habitat, but in the paleoanthropology section, most of our knowledge is based on data gathered through archaeology, and we focus on hominid fossils, and how to interpret them. The next few sections are going to bombard you with specific dates, exotic places, hard to pronounce names, and plenty of Latin. Please try not to miss the forest for the trees. We need to sweat the details.

Paleoindian Period

Human biological evolution began in the Old World, and Native Americans are relatively recent arrivals to the New World. Their physical resemblance to the people of East Asia has long been recognized. More specifically, based on similarities in language, teeth, and DNA, there is nearly unanimous agreement that the ancestors of the Native Americans originated in Asia. The land bridge connected Siberia with Alaska and would have included the Aleutian Islands.

Using relative and radiometric dating methods, geologists are able to answer the been built and eroded, continents and oceans have moved great distances, and There are three general approaches that allow scientists to date geological correlate a particular paleomagnetic reversal to a known reversal in the GPTS.

Paleoanthropology , also spelled Palaeoanthropology, also called Human Paleontology , interdisciplinary branch of anthropology concerned with the origins and development of early humans. Fossils are assessed by the techniques of physical anthropology , comparative anatomy , and the theory of evolution. Artifacts , such as bone and stone tools, are identified and their significance for the physical and mental development of early humans interpreted by the techniques of archaeology and ethnology.

How Bioarchaeology Works

The Topper site is one of the most remarkable Paleoindian sites ever found in the Southeastern United States, with well-preserved remains dating from the present back to upwards of 13, calendar years before the present. The Clovis remains from the site, from a culture dating from ca. Likewise, a remarkable Late Woodland occupation has been found at the site, roughly dating from ca. AD to

Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.

Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample. In recent years, a few of these methods have come under close scrutiny as scientists strive to develop the most accurate dating techniques possible.

Figure 1. Paleoanthropology , a subdiscipline of anthropology, is the study of extinct primates. While the majority of researchers doing this kind of work are anthropologists, paleontologists within the discipline of geology may also study fossil primates. The primary method used by paleoanthropologists is the analysis of fossil remains.

dates and ugly dates,” says paleoanthropologist John Shea of Stony Brook University. They then use that absolute date to establish a relative age for fossils and the sample is so small, and the contamination risk so great, that the Archaeologists also frequently use TL to date ceramics, which are.

The announcement of a new species of ancient human more correctly hominin from the Philippines, reported today in Nature , will cause a lot of head-shaking among anthropologists and archaeologists. Some will greet the publication with wild enthusiasm, believing it confirms their own views about our evolutionary past.

Others will howl angrily, believing the declaration goes way too far with too little evidence. Me, I sit somewhere in the middle of this spectrum of opinions.

There is no reason to expect human evolution to have been any different to the evolution of other animals where, for example, among our close primate relatives, diversity was and often continues to be the rule.

At the same time, each and every new discovery has to stack up and must be judged on its merits, on the basis of the evidence presented. But we need also to keep a cool head, because the naming of any new species is still a scientific hypothesis, ripe for testing and far from set in stone, even if published in the esteemed pages of a journal like Nature. So, just what have they found? This new hominin is represented by a handful of heavily worn adult teeth from one or two individuals, one foot and two toe bones, two finger bones, and the fragment of the shaft of a juvenile thigh bone.

Its anatomy is argued to be a peculiar mix of features normally found in living humans, Homo erectus , the Hobbit Homo floresiensis and Australopithecus. The similarities to Australopithecus are especially intriguing when one ponders for a moment on just who the australopiths actually were. Another is Australopithecus sediba , from a cave in South Africa and found just a decade ago. These and the many other Australopithecus species and there are at least six described lived only in sub-Saharan Africa, between about 2 million and 5 million years ago.

Why Is Dating So Important For Paleo Anthropologists And Archaeologists

Signing up enhances your TCE experience with the ability to save items to your personal reading list, and access the interactive map. For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.

There are two main categories of dating methods in archaeology : indirect or relative dating and absolute dating.

Archaeology is the study of the human past using material remains. These remains can be any objects that people created, modified, or used. Portable remains are usually called artifact s.

Artifacts include tools, clothing, and decorations. Non-portable remains, such as pyramid s or post-hole s, are called feature s. Archaeologist s use artifacts and features to learn how people lived in specific times and places. Sometimes, artifacts and features provide the only clues about an ancient community or civilization. Prehistoric civilizations did not leave behind written records, so we cannot read about them.

Understanding why ancient cultures built the giant stone circles at Stonehenge , England, for instance, remains a challenge 5, years after the first monolith s were erected. Archaeologists studying Stonehenge do not have ancient manuscript s to tell them how cultures used the feature.

Topper Site Archaeological Project

It was founded in and evolved out of the Sundance Archaeological Research Fund, created in through a generous endowment given to the University of Nevada, Reno Foundation. The purpose of the endowment is to support long-term archaeological research in the Intermountain West with a focus on the Pleistocene-Holocene transition. Typically, the GBPRU funds three-to-four graduate research assistantships per year, awarded on a competitive basis.

Assistants work with faculty on research projects and undertake independent research of their own. This work offers graduate and undergraduate students opportunities to gain on-the-job training and prepare for a career in academic archaeology. The unit encourage students of all levels to formulate and pursue independent and collaborative research projects and support presentation and publication efforts.

Louis Leakey was born on August 7, , in Kenya, and, with wife Mary Leakey, established an excavation site at Olduvai Gorge to search for fossils. The team made unprecedented discoveries of hominids millions of years old linked to human evolution, including H. Leakey, an avid lecturer and author who also worked in primatology, died on October 1, In , he travelled to England to be educated in anthropology and archaeology at St.

John’s College, Cambridge University, ultimately earning his doctorate in African prehistory. He held fast to Charles Darwin’s belief that humanity had originated from Africa, defying conventional beliefs that the species’ origins were from Asia or Europe. Leakey returned to the continent of his birth to take up Eastern archaeological expeditions in the mids, later publishing work on his hominid discoveries. Leakey made his first trip to Olduvai Gorge, located in modern day Tanzania, in The site would eventually become one he was famous for.
