The age of fossils are determined by carbon dating and by radioactive calculations. Since all living things are made up of carbon, the relative age of fossils, which were once live animal or plant life, can be calculated by estimating at what time the fossil...

Fossils provide geologists, archaeologists and biologists with the evidence necessary to understand the biodiversity of Earth, both now and throughout history. Through the process of fossilization, biological remains are preserved for incredibly long periods of time. These remains provide records from the specific time the...

The Ice Age lasted around one hundred thousand years from about 110,000 to 10,000 years ago. The ice grew and retreated over this time but the largest extent of ice glaciers was around 18,000 years ago. The ice covered most of the...
Researchers: Dinosaurs survived 700 millennia after asteroid impact

Following the devastating impact of a miles wide asteroid with the Earth 65 million years ago the race of dinosaurs went extinct, right?Not so, says a research team at the University of Alberta, Canada. New dating method raises doubts about current extinction theoryFor years...

Carbon-14 dating, also known as radio carbon dating is one of the most commonly used methods for determining estimated ages of organic materials such as fossils. Carbon dating measures the amount of specific isotopes of carbon in an object and compares that number to the...

Carbon is an element with 7 isotopes ranging in atomic mass unit (amu) from 9 to 15. All isotopes of any element contain a set number of protons and electrons, but the number of neutrons can vary establishing unique isotopes exhibiting the same elemental properties...

Every living thing, animal or plant must have carbon to live and this is being taken in, or constantly, else the organism dies. Carbon dioxide is the process formed after an oxidation process has taken place. The food eaten is oxidized and the resultant used...
How carbon-14 dating works
By: Hai Shunxi
Carbon is one of the most common elements on Earth, and is one of the building blocks of every living thing. There is, however, more than one kind of carbon. An ordinary carbon atom has six protons and six neutrons inside its nucleus, for an...

Since its development by J. R. Arnold and W. F. Libby in 1949, radiocarbon dating has proved a valuable resource in dating some archeological and paleontological remains. This form of dating requires some form of previously living matter such as wood or other plant material...

The fossilized skull of a gigantic sea monster that attacked and ate whales was unearthed in an ancient seabed along the arid wilderness of the Peruvian coast. The remains of the incredible creature are so huge, researchers have dubbed it "the Leviathan." The Leviathan...
