Radiocarbon dating dinosaurs

Carbon-14 has a half-life of 5,730 ± 40 years— during the succeeding 5,730 years.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

National Geographic reports that scientist Dallas Abbott from Columbia University has been gathering data and announcing for the past ten years that a giant tsunami deposited ocean floor sediment on Madigascar.

The sediments cover an area 2 times the size of Manhattan and are over 600 feet tall.

Archaeology is an important field of anthropology, which is the broad study of human culture and biology.

Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.

ASTEROIDS: Scientists have discovered a very large asteroid impact site in Antarctica.

A fossil only becomes a fossil when it has reached a certain age.

The most widely known form of radiometric dating is carbon-14 dating.

This is what archaeologists use to determine the age of human-made artifacts. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old.
