A fossil from Classical Latin : fossilis , literally "obtained by digging" [1] is any preserved remains, impression, or trace of any once- living thing from a past geological age. Examples include bones , shells , exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair , petrified wood , oil , coal , and DNA remnants. The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host. There are many processes that lead to fossilization, including permineralization , casts and molds, authigenic mineralization , replacement and recrystallization, adpression, carbonization , and bioimmuration. A fossil normally preserves only a portion of the deceased organism, usually that portion that was partially mineralized during life, such as the bones and teeth of vertebrates , or the chitinous or calcareous exoskeletons of invertebrates. Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces coprolites. These types of fossil are called trace fossils or ichnofossils , as opposed to body fossils. radiocarbon dating is done by estimating in the specimenSome claim the image depicts Jesus of Nazareth and the fabric is the burial shroud in which he was wrapped after crucifixion. First mentioned inthe shroud was denounced in by the local bishop of Troyes as a fake. Inradiocarbon dating established that the shroud was from the Middle Agesbetween the years and However, all of the hypotheses put forward to challenge the radiocarbon dating have been scientifically refuted, [9] including the medieval repair hypothesis, [10] [11] [12] the bio-contamination hypothesis [13] and the carbon monoxide hypothesis. The image on the shroud is much clearer in black-and-white negative —first observed in —than in its natural sepia color.
A variety of methods have been proposed for the formation of the image, but the actual method used has not yet been conclusively identified. The shroud is rectangular, measuring approximately 4.
Introduction
The cloth is woven in a three-to-one herringbone twill composed of flax fibrils. Its most distinctive characteristic is the faint, brownish image of a front and back view of a naked man with his hands folded across his groin. The two views are aligned along the midplane of the body and point in opposite directions.
The front and back views of the head nearly meet at the middle of the cloth. The image in faint straw-yellow colour on the crown of the cloth fibres appears to be of a man with a beard, moustache, and shoulder-length hair parted in the middle. He is muscular and tall various experts have measured him as from 1.

In May Italian photographer Secondo Pia was allowed to photograph the shroud. He took the first photograph of the shroud on 28 May Inanother photographer, Giuseppe Go here, photographed the shroud and obtained results similar radiocarbon dating is done by estimating in the specimen Pia's. The shroud was damaged in a fire in in the chapel in ChamberyFrance. There are some burn holes and scorched areas down both sides of the linen, caused by contact with molten silver during the fire that burned through it in places while it was folded.
The historical records for the shroud can be separated into two time periods: before and from to the present. Prior to there are some similar images such as the Pray Codex. However, what is claimed by some to be the image of a shroud on the Pray Codex has crosses on one side, an interlocking step pyramid pattern on the other, and no image of Jesus. Critics point out that it may not be a shroud at all, but rather a rectangular tombstone, as seen on other sacred images.
The first possible historical record dates from or[16] [28] and the first certain record in LireyFrance in when Bishop Pierre d'Arcis wrote a memorandum to Pope Clement VII Avignon Obediencestating that the shroud was a forgery and that the artist had confessed. There are no definite historical records concerning the particular shroud currently at Turin Cathedral prior to the 14th century. A burial cloth, which some historians maintain was the Shroud, was owned by the Byzantine emperors but link during the Sack of Constantinople in The history of the shroud from the 15th century is well recorded.
In the shroud was transferred to Turin. Since the 17th century the shroud has been displayed e. A drop of molten silver from the reliquary produced a symmetrically placed mark through the layers of the folded cloth. Poor Clare Nuns attempted to repair this damage with patches. The shroud remained the property of the House of Savoy untilwhen it was given to the Holy See.
A fire, possibly caused by arsonthreatened the shroud on 11 April The cloth backing and thirty patches were removed, radiocarbon dating is done by estimating in the specimen it possible to photograph and scan the reverse side of the cloth, which had been hidden from view. A faint part-image of the body was found on the back of the shroud in The Shroud was placed back on public display the 18th time in its history in Turin from 10 April to 23 May ; and according to Church officials, more than 2 million visitors came to see it. On Holy Saturday 30 Marchimages of the shroud were streamed on various websites as well as on television for the first time in 40 years. The shroud was again placed on display in the cathedral in Turin from 19 April until 24 June ]
