Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging. These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.
Ancient Tattoos: Archaeologists find Blood and Pigments on 3,000-Year-Old Obsidian
Astronomy Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in ice that are easily counted to multiple tens of thousands of years, and when combined with radio isotope dating, we find hundreds of thousands of years of ice layers. Using the known rate of change in radio-active elements radiometric dating , some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.
Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years. The expansion of the universe gives an age for the universe as a whole:
The study and discovery of Otzi will help demonstrate the archaeological concepts and processes involved in Excavation, Preservation and Dating techniques. This is dependent on the nature and age of the object in question.

During the first stage of investigations Austrian archaeologist Konrad Spindler researched the layout which had proved that the iceman’s body position and placement of weapons were preserved in the same position from when the Iceman had died, it had also been proved that the body was initially covered in a thin layer of snow which had helped complete the freeze drying process before it turned into ice.
The body had been so well preserved because of the depth that the Iceman was actually lying in the ground, which was near the watershed watershed meaning a line of high land where streams on one side flow into one river or sea and streams on the other side flow into another. This meant that a glacier would be able to develop above him throughout the next millennia without moving his position down hill. In this position he was able to remain buried, frozen, covered and protected by the cold over a period of 5, years as the worlds oldest, best preserved natural mummy.
Source 2 Scientists believe that the Iceman’s tattoo’s were first applied in 3, BC, the first evidence of acupuncture. Dr Frank Bahr President of the German Academy for Acupuncture who studies the trends and patterns of the iceman’s tattoos, believes that the cruciform, meaning cross-shape, tattoo and a master point tattoo on his back were applied in order to treat rheumatism. Bahr says “”These points would still be selected by the best acupuncturists today.
Body art is one of the oldest forms of creative expression known to man-kind, cave paintings date it back to almost BC. The spread of tattooing although presumed to have began much earlier was first recorded in Egypt during the building of the pyramids.
Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed. Five years later we are at scale, moving the needle and doing to WordPress what Airbnb did to Craigslist. Social and Centralized WordPress, Drupal, and the custom CMS solutions of the world are all independent, non-connected instances that each need to be updated individually.
There are over 87 million instances of WordPress alone in the world, and each security upgrade, feature update, and every other single thing has to be updated for each site individually. By contrast, RebelMouse is a social, centralized platform built to keep up with the speed of the tech giants. Our updates are pushed out to all of our sites at once and sometimes even multiple times a day with content creation tools integrated directly into social APIs.
The Art of Prehistoric Textile Making. The development of craft traditions and clothing in Central Europe Textile crafts, and weaving in particular, have contributed much to the overall development of technology. Essential goods for daily use, especially Essential goods for daily use, especially clothing, as well as utilitarian textiles, ostentatious objects for display and luxury items were produced with this craft.
Textiles were valuable, as can be inferred from the recycling of fabrics. Worn out garments were used as binders, packaging and even as a dressing material in prehistoric times. Clothing, however, not only offered protection against the elements — even in prehistoric times textiles and jewellery were more than just simply means to dress — they are an essential feature of every culture. In the past as well as today, clothing represents an important non-verbal means of communication and conveys aspects of identity about the wearer such as age, gender, social status and group memberships.

Dating Methods in History and Archaeology
Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. All methods can be classified into two basic categories: Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.
These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials. This method includes carbon dating and thermoluminescence.
This study documents for the first time the complete mapping of one of the world’s most ancient tattoos present on a mummified human body dating back to over .
Those who build a strong track record of specific and correct predictions concerning the future would establish greater credibility than those who maintain a poor record. Over time, the world would be able to identify which voices should be given the most weight when making decisions concerning the future. This is a great idea, and if we are objective in setting up our predictions registry, the source which ranks as the 1 most reliable repository of information concerning the future is clear.
That source is the Bible. Although billions of people quote, read, and study the Bible every year, most of the world remains ignorant of the staggering number of specific prophecies found in the Bible. Yet despite the millions of people who attend church and synagogue every week and the existence of countless books on the subject, most people are simply unaware of these prophecies. They feverishly search through the writings of Nostradamus, Edgar Cayce, the Koran, and countless other sources in hopes of finding a profound truth or revelation concerning the future, only to be disappointed.
Yet, the most credible source of information on future events, the Bible, somehow escapes notice. In addition, I remain boggled by the number of educated and intelligent people who, without investigation, dismiss the validity of these amazing biblical prophecies, despite mountains of historical data, archaeological evidence, and the staggering mathematical probability of their occurrence merely being the result of chance.
Biblical prophecies can be divided into the following three categories: Fulfilled Bible Prophecies A number of prophecies found in the Bible have already been fulfilled. For instance, in the Book of Daniel, the prophet Daniel identifies the ascendance and succession of world empires that would be established throughout history, from the time he spoke until the end of the age.
He even identifies the breakup of the Greek Empire into four separate kingdoms following the death of Alexander the Great.
OTZI, THE ICEMAN
The various dating techniques available to archaeologists by Michael G. Furthermore, when you consider that many archaeological sites will contain numerous types of artifacts that permit the use of multiple dating methodologies, a modern archaeologist can often employ cross-dating methodologies which can allow for extremely accurate dating as far back as 10, years in some regions. Natural Dating Techniques A modern archaeologist has almost half a dozen natural dating techniques that she can apply in the field that she can use to quickly determine an approximate date range, which, in the cases of varve analysis and dendrochronology, can often be used to decrease the date range estimate to a matter of just a few years.
One of the oldest natural dating techniques is geochronology, which is based on the principle of superposition — an object, or layer, on top must have been placed there at a later point in time.
Since his discovery in the Tollund Man has undergone continuous and thorough examinations using the latest methods. Shortly after the discovery the Tollund Man was excavated and examined at the National Museum of Denmark in Copenhagen. The examination was done with the same kind of care and accuracy as if he had been the victim of a murder.
It was discovered in in the Alps and since then it has not stopped leaking information about what life was like in the Neolithic. Do you dare to find out all its secrets? Mummies are preserved bodies of people and animals that still preserve their skin. The most famous are the Egyptian ones, preserved thanks to the chemical processes applied to the corpses embalming , although many other cultures practiced mummification. But mummies can also occur naturally if the conditions are suitable to avoid decomposition, such as humid and swampy sites, in the cold of mountains and polar regions or in dry and sandy areas such as deserts.
In addition to the skin, other structures that can be preserved over the millennia are nails, hair and bones and teeth. Natural mummy in the British Museum, London.

He was around 5’ 2” tall and weighed approximately pounds at death. which would account for the spreading of techniques like tattooing and medical knowledge of energy meridians. In , an.
However, chronological data is crucial to many types of analysis in which rock art evidence is integrated with other archaeological and environmental information. This section will briefly survey the range of dating techniques used in contemporary rock art studies. These fall into two broad categories: Geological time-scales Accurate knowledge of the age of the Earth was of little direct help to archaeologists, but it emphasised the potential of scientific dating techniques. The first half of the twentieth century witnessed similar progress that began with the dating of recent geological periods in which early hominids lived, and ended with the introduction of radiocarbon dating.

The Scientific Flaws of Online Dating Sites
Paul, Minnesota The purpose of this article is to present an overview of some of the advanced scientific techniques that are currently being used to evaluate artifacts. Paul, Minnesota to demonstrate some of the techniques and provide a basis for discussion in this article. Background The artifact collecting community has routinely used techniques such as microscopic analysis and ultra-violet inspection in the evaluation of artifacts, but the use of advanced imaging technology, scientific dating methods, and materials characterization techniques have rarely been used.
Most collectors have had to rely on personal experience and the use of basic techniques to evaluate their artifacts.
We have all seen forensic scientists in TV shows, but how do they really work? What is the science behind their work? The course aims to explain the scientific principles and techniques behind the work of forensic scientists and will be illustrated with numerous case .
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.
Isotope Analysis Methods In order to investigate stable isotopes from human and animal bones, a very small sample of bone is needed for the analysis. Due to advances in accelerated mass spectrometry AMS a small sample which can range from milligrams to 1gram of bone can be used. When archaeological bone material is poorly preserved there may not be enough surviving biological material left for the analysis to be reliable. However, in cases where the bones are well preserved, the isotopic signatures are considered to be representative of the individual specimen either human or animal that is being studied.
The small bone sample is then treated through a set of chemical procedures, depending on the particular analysis in question. For example, for analysis of carbon and nitrogen stable isotopes, the bone is washed in hydrochloric acid HCl for an appropriate period of time until the bone sample is ready for the next chemistry steps. These processes are carried out to extract the “pure” bone collagen from additional components that make up bone, such as lipids and proteins.
