Carbon 14 dating archeology


Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.

Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.

Even in this age of computers and x-rays, archaeologists still have to use basic methods like digging and measuring to insure that they collect the best information possible. So far the data base contains "8 billion polygons and 6 thousand color images, occupying 40 gigabytes." Solving the puzzle, says the team, "will take months, possibly years." You come across a buried staircase that leads down into the desert. But today a battery of new tools is helping to bring the past back to life.

The first task of the American researchers was simple: 3-D scan each individual block into their computer. You open the first doors you see — they lead to a long passageway and an antechamber. But there are other doors, undisturbed for centuries. Archaeology, notes one of its practitioners, "has a long disreputable line of descent; its ancestors were, quite literally, grave robbers and adventurers." Foremost amongst them ranks the Italian Giovanni Belzoni.

Eighteen-hundred years ago it hung in the Roman census bureau, the most detailed map of the city ever produced. Today it languishes in the basement of a museum, smashed.

Now a team of American researchers have devised a novel way of pasting it together again — by scanning it into a computer.

Recently, he appeared on the evening news to talk about a new dinosaur he just discovered. Paul says he can tell from the fossils that superus awesomus lived on Earth about 175 million years ago.

As per the scientist involved such features are unlikely to be due to natural marine geological processes.For the Jewish People, ancient Egypt has a much deeper allure.Much of the first two books of the Torah takes place in Egypt.Over 100,000 books have been written on this inscrutable land and its pharaohs, the first one being composed over 2000 years ago.By the time the Hellenistic historian, Manetho, composed his Aegyptiaca in the third century BCE, the pharaoh of the Exodus had already been mummified about 1,000 earlier.On , India's Union Minister for Human Resource Development, Science and Technology division, Murli Manohar Joshi, announced that the ruins of an ancient civilization had been discovered off the coast of Gujarat, in the Gulf of Khambhat.The site was discovered by NIOT while they performed routine pollution studies using sonar, and was described as an area of regularly spaced geometric structures.But really, how do scientists figure out how old their dinosaur bones are?And, what about other findings like fossil fish, plants and insects?It is located 20 km from the Gujarat coast, spans 9 km, and can be found at a depth of 30–40 meters.In his announcement, Joshi represented the site as an urban settlement that pre-dates the Indus Valley Civilization.
