This article was published in a three-part series in the magazine Secular Nation, at the suggestion of Dr. Robert Price, who called the series “fine articles. In the week of October 21, , headlines around the world screamed that evidence of Jesus Christ had been found in the form of an ossuary, or bone-box, supposedly once containing the bones of “James, son of Joseph, brother of Jesus,” as was inscribed on the box in Aramaic. The original scholar who reported this spectacular find, the Sorbonne’s biblical expert Andre Lemaire, “born a Catholic,” concluded it was “very probable” that the inscription referred to Jesus of Nazareth, i. The ossuary, therefore, would supposedly be that of the biblical “James the Just,” who is referred to as Jesus’s “brother” at Matthew Naturally, Christian apologists and fanatics rubbed their hands together, and gleefully and smugly bombarded nonbelievers with the news via email.

These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus slowing decomposition. Stromatolites Lower Proterozoic Stromatolites from Bolivia , South America Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms , especially cyanobacteria. While older, Archean fossil remains are presumed to be colonies of cyanobacteria , younger that is, Proterozoic fossils may be primordial forms of the eukaryote chlorophytes that is, green algae.
One genus of stromatolite very common in the geologic record is Collenia.
Another chemical dating technique available to archaeologists for dating bone is the bone-nitrogen dating technique. Bones buried in soil lose organic components, and nitrogen in particular, and gain inorganic components, such as fluorine and uranium, in their place.
Within ten years he had enlarged the factory three times, built a china works, taken on the largest and most gifted group of artists in the Potteries, and developed for Doulton a reputation for craftsmanship and artistry still identified with Royal Doulton today. There follows a selection of the backstamps most commonly used on Doulton Burslem wares, and some further hints on dating. The information is taken by permission from “The Doulton Burslem Wares” by Desmond Eyles, a compulsory work of reference for any collector of Doulton wares see back page.
The reference numbers for the Doulton Burslem marks have been prefixed by the letter ‘B’ to distinguish them from those also numbered 1 and up in the list of Lambeth marks given in The Doulton Lambeth Wares. Several of these were adopted after by Doulton and remained in use for about twenty years. The following are two typical examples found on the patterns Rouen and Kew. Various other pattern names will be found.

The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself. The baby will be measured, and the anatomy examined in detail.
Radiocarbon dating results on bones need not be subjected to an age offset but bone samples have time-width. Literature suggests that a bone does not cease to assimilate carbon from the biosphere until death; there is a turnover time of about 30 years for human bone and a shorter period for animal bone.
Without it, nothing can be done. For chefs, stock is the magic elixir for making soul-warming soups and matchless sauces. In America, stock went into gravy and soups and stews. That was when most animals were slaughtered locally and nothing went to waste. Bones, hooves, knuckles, carcasses and tough meat went into the stock pot and filled the house with the aroma of love. Today we buy individual filets and boneless chicken breasts, or grab fast food on the run, and stock has disappeared from the American tradition.
Grandmother Knew Best Science validates what our grandmothers knew. Rich homemade chicken broths help cure colds. Stock contains minerals in a form the body can absorb easily—not just calcium but also magnesium, phosphorus, silicon, sulphur and trace minerals. It contains the broken down material from cartilage and tendons—stuff like chondroitin sulphates and glucosamine, now sold as expensive supplements for arthritis and joint pain. Fish stock, according to traditional lore, helps boys grow up into strong men, makes childbirth easy and cures fatigue.
Broth and soup made with fishheads and carcasses provide iodine and thyroid-strengthening substances. When broth is cooled, it congeals due to the presence of gelatin. The use of gelatin as a therapeutic agent goes back to the ancient Chinese.

By the beginning of this time, handaxes were made with exquisite craftsmanship, and eventually gave way to smaller, more diverse toolkits, with an emphasis on flake tools rather than larger core tools. These toolkits were established by at least , years in some parts of Africa, and by , , years in Europe and parts of western Asia. This technique probably raised the level of standardization and predictability in stone technology. Middle Stone Age toolkits included points, which could be hafted on to shafts to make spears.
Structure[ edit ] Cross-section of bone Bone is not uniformly solid, but includes a tough matrix. Its matrix is mostly made up of a composite material incorporating the inorganic mineral calcium phosphate in the chemical arrangement termed calcium hydroxylapatite this is the bone mineral that gives bones their rigidity and collagen , an elastic protein which improves fracture resistance. When these cells become entrapped from osteoblasts they become osteocytes.
It forms the hard exterior cortex of bones. It consists of multiple microscopic columns, each called an osteon. Each column is multiple layers of osteoblasts and osteocytes around a central canal called the haversian canal. Volkmann’s canals at right angles connect the osteons together. The columns are metabolically active, and as bone is reabsorbed and created the nature and location of the cells within the osteon will change.
Cortical bone is covered by a periosteum on its outer surface, and an endosteum on its inner surface. The endosteum is the boundary between the cortical bone and the cancellous bone.

At the same time, prehistoric art took a massive leap forward, as exemplified by the cave painting of western Europe, that reached its apogee on the walls and ceilings of Lascaux Cave France and Altamira Cave Spain , both of which contain some of the greatest examples of Franco-Cantabrian cave art , from the Solutrean-Magdalenian era, dating to between 17, and 15, BCE. See also the magnificent bison paintings at Font de Gaume Cave in the Perigord.
Discovered in , close to the village of Montignac, in the Dordogne region of southwestern France, Lascaux is especially famous for its painting , which includes a rare example of a human figure; the largest single image ever found in a prehistoric cave the Great Black Bull ; and a quantity of mysterious abstract signs, which have yet to be deciphered. In total, Lascaux’s galleries and passageways – extending about metres in length – contain some 2, images, about of which are animals, and the remainder geometric symbols of varying shapes.
The sheer number of images, their size and exceptional realism, as well as their spectacular colours, is why Lascaux like Altamira is sometimes referred to as “The Sistine Chapel of Prehistory”. Like the Chauvet Cave paintings , Lascaux’s cave art was protected by a landslide which sealed off access to the cave around 13, BCE. Not long after its opening in , Pablo Picasso paid a visit and was amazed at the quality of the cave’s rock art , saying that man had learned nothing new since then.
In , due to continuing environmental problems inside the cave, Lascaux was closed to the public. In , an exact replica of the Great Hall of the Bulls and the Painted Gallery – created under Monique Peytral and known as “Lascaux II” – was opened a few hundred metres from the original cave, and it is this replica that visitors see today.
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. Once a geologist has determined the absolute age of a geological formation, the archaeologist can assign an indirect date to objects found in the formation. In archaeology, geochronology lays the foundations for the dating technique better known as stratigraphy that assesses the age of archaeological materials by their association with geological deposits or formations.

Since the rise of online dating over the past decade, many dating websites have come and gone. A common complaint shared by seasoned online daters who have tried various dating sites is that, rarely do the multitude of matchmaking services live up to their claims. For a monthly fee, dating sites claim they’ll do the math for you and spit out your soul mate in return.
Some websites gather data about you and crunch the numbers with all kinds of mathematical formulas and algorithms in order to fill up your inbox with compatible matches. A recent report issued by the New York Times weighs in explaining why numbers and formulas are unlikely to help forge the perfect couple. Hang on a minute, wasn’t online dating designed to reduce the complexities of finding a partner in the first place?
Technology and competition for this lucrative market has made a mockery of it. To the average person, thanks to bad press and other contributing factors, online dating has become somewhat of an un-trusted source for meeting people. So why are we different here at Free Dating America? The simple truth is that, people like to explore the pool of singles by sifting through simple location based searches and not relying on an algorithm and a bunch of gimmicks, not to mention a cash grab, in order to find someone they like the look of.
And besides, it’s fun! And that’s what you’ll get once you partner with us to help find your new friend or lover – simple, powerful and instant results based on a few basic steps that will deliver you the choice to pick and choose as you please.

At Free Dating America, it’s our number 1 priority not to let these scumbags on our website!
This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won’t work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life.

Chalfant — in his book Early Chinese Writing. Neolithic signs in China It is certain that Shang-lineage writing underwent a period of development before the Anyang oracle bone script because of its mature nature. The few Neolithic symbols found on pottery, jade, or bone at a variety of cultural sites in China are very controversial, and there is no consensus that any of them are directly related to the Shang oracle bone script.
The earliest oracle bone script appears even more so than examples from late in the period thus some evolution did occur over the roughly year period. The more detailed and more pictorial style of the bronze graphs is thus thought to be more representative of typical Shang writing as would have normally occurred on bamboo books than the oracle bone script forms, and this typical style continued to evolve into the Zhou period writing and then into the seal script of the Qin in the late Zhou period.
Additional support for this notion includes the reorientation of some graphs, [f] by turning them 90 degrees as if to better fit on tall, narrow slats; this style must have developed on bamboo or wood slat books and then carried over to the oracle bone script. Additionally, the writing of characters in vertical columns, from top to bottom, is for the most part carried over from the bamboo books to oracle bone inscriptions.
Oracle bone inscriptions, however, are often arranged so that the columns begin near the centerline of the shell or bone, and move toward the edge, such that the two sides are ordered in mirror-image fashion. This level of maturity clearly implies an earlier period of development of at least several hundred years. Compare, for instance, the third and fourth graphs in the row below.
