Cultural History This overview of the prehistory and history of southeastern New Mexico, specifically the lower Pecos River to the Texas border, is designed to address two areas. First, this overview will briefly outline broad temporal periods and mention some of the previous fieldwork that was used in their definition in southeastern New Mexico. A discussion section follows and addresses theoretical and methodological issues that affect our knowledge of that temporal period. The methodological discussion includes information that can be derived from survey and excavation. The beginning of human occupation of the eastern slopes of the Sacramento Mountains is unknown. Evidence for limited use of the area from at least 20, years ago has been documented from Pendejo Cave located on the eastern edge of the Tularosa Basin MacNeish and Libby The earliest record of human occupation in southern New Mexico is indicated by the occurrence of generalized lithic toolkits associated with the remains of Pleistocene mammals and plants with radiocarbon dates ranging back to forty thousand years ago at Pendejo Cave near Oro Grande MacNeish and Libby
The Radiocarbon Revolution Since its development by Willard Libby in the s, radiocarbon 14C dating has become one of the most essential tools in archaeology. Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials.
In contrast to relative dating techniques whereby artifacts were simply designated as “older” or “younger” than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.
The application of Accelerator Mass Spectrometry AMS for radiocarbon dating in the late s was also a major achievement. Compared to conventional radiocarbon techniques such as Libby’s solid carbon counting, the gas counting method popular in the mid s, or liquid scintillation LS counting, AMS permitted the dating of much smaller sized samples with even greater precision.
Duane Cloud Duane has taught teacher education courses and has a Doctorate in curriculum and instruction. His doctoral dissertation is on ”The Wizard of Oz”. This lesson will describe the science of archaeology. Topics will include the definition and history of archaeology, as well as a brief description of its sub-disciplines. Perhaps the most famous fictional archaeologist is Stephen Spielberg’s Indiana Jones. Jones is the main character in a variety of action films involving lost artifacts and civilizations, cults, and Nazis.
Jones carries his signature whip and hat, and regularly tussles with a wide variety of armed antagonists. However, the filmmakers took a number of liberties with Dr. Jones’ occupation as an archaeologist to make things a bit more interesting for viewers. So, what exactly is archaeology?
Definition of ‘radiocarbon dating’
Archaeology, which is situated between the hard natural sciences and social sciences, has adapted the techniques developed in these fields to answer both archaeological and anthropological questions that span the globe over both time and space. The questions that are addressed within the field of Archaeology most commonly relate to the study of diet and mobility in past populations. While most people are familiar with isotopic analysis related to the study of radiocarbon dating or C , fewer are familiar with the analysis of other isotopes that are present in biological material such as human or animal bone.
The stable isotopes of 13C, 15N and 18O differ from the analysis of 14C in that they do not steadily decay over time, thus there is no “half-life. The exploration of isotopic identifiers of mobility, environment, and subsistence in the past also has contemporary relevance in that it can aid in informing policies relating to heritage protection, resource management and, sustainability and perhaps most significantly, help us to learn more about the remarkable ability of our own species to adapt and survive in any number of environmental and cultural circumstances.

Archaeologists work with the material remains of cultures, past and present, providing the only source of information available for past nonliterate societies and supplementing written sources for historical and contemporary groups. History of Archaeology The discipline had its origins in early efforts to collect artistic materials of extinct groups, an endeavor that can be traced back to the 15th cent.
In the 18th cent.
seriation CATEGORY: technique DEFINITION: A relative dating technique in which artifacts or features are organized into a sequence according to changes over time in their attributes or frequency of appearance. The technique shows how these items have changed over .
It is difficult for today’s students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians.
Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time – a point little appreciated by modern archaeologists. Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: The latter like stratigraphic excavation measures time discontinuously, while the former – in various guises – measures time continuously.
Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques. Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history.

Resources Introduction Archaeology is the study of the ancient and recent human past through material remains. It is a subfield of anthropology, the study of all human culture. From million-year-old fossilized remains of our earliest human ancestors in Africa, to 20th century buildings in present-day New York City, archaeology analyzes the physical remains of the past in pursuit of a broad and comprehensive understanding of human culture.
Back to top How does archaeology help us understand history and culture? Archaeology offers a unique perspective on human history and culture that has contributed greatly to our understanding of both the ancient and the recent past. Archaeology helps us understand not only where and when people lived on the earth, but also why and how they have lived, examining the changes and causes of changes that have occurred in human cultures over time, seeking patterns and explanations of patterns to explain everything from how and when people first came to inhabit the Americas, to the origins of agriculture and complex societies.
Unlike history, which relies primarily upon written records and documents to interpret great lives and events, archaeology allows us to delve far back into the time before written languages existed and to glimpse the lives of everyday people through analysis of things they made and left behind. Archaeology is the only field of study that covers all times periods and all geographic regions inhabited by humans.
It has helped us to understand big topics like ancient Egyptian religion, the origins of agriculture in the Near East, colonial life in Jamestown Virginia, the lives of enslaved Africans in North America, and early Mediterranean trade routes. In addition archaeology today can inform us about the lives of individuals, families and communities that might otherwise remain invisible. Back to top Types of Archaeology Prehistoric archaeology focuses on past cultures that did not have written language and therefore relies primarily on excavation or data recovery to reveal cultural evidence.
Historical archaeology is the study of cultures that existed and may still during the period of recorded history–several thousands of years in parts of the Old World, but only several hundred years in the Americas.
Archaeology and Dating by Israel Finkelstein Transcript I see myself as an historian practicing archaeology, so dating is important. Now we know today to establish relative dating very well, which means what comes first, what comes next, the different phases of the Iron Age ; and this is being done according to pottery assemblages. The pottery is essential for establishing the relative chronology; but the question is how to tell from relative chronology to absolute chronology to a date which can give us the background for historic reconstruction.
Radiocarbon dating was invented in the late ‘s, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years.
What parts of the brain that process language? There is no one area of the brain involved in processing language, and knowledge of all areas of the brain involved in processing language and communication are still growing and developing. Below is a partial compilation of the currently known accepted areas of the brain involved in the processin…g of communication and language.
Keep in mind that language is one of the biggest endeavors of all humans. It is a whole body experience. It involves all avenues of communication, all six senses: As far as the parts of the brain that are involved in processing language, so far as we know to date, these are listed below: The Brodmann area BA 44 of the inferior frontal gyrus processes syntactic information and is also a working memory area. Brocas area of the inferior frontal gyrus is directly involved in speech, speech processing, and speech development.
Middle temporal gyrus MTG , involved in lexical semantic processing of word use and meaning processing. Basal temporal cortex, helps in lexical word processing. Primary visual cortex – processes visual information. Dorsal Stream – the “where” and “how” stream. The dorsal stream connects the occipital and parietal lobes and aids in processing spacial, navigational, and chronological information.
