For example, radiocarbon dating only works for fossils that are 50,000 years old or younger, while amino acid dating fell out ...

First, the relative age of a fossil can be determined. Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event.

Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. Radiocarbon dating, or carbon-14 dating, is a ...

Google's latest Doodle celebrates the discovery of Staurikosaurus fossils, an agile dinosaur from the Late Triassic period ...

It can date materials and artefacts like plants, fossils, bones and soil up to about 50,000 years old. The problem is that existing radiocarbon dating techniques are expensive, energy intensive ...

Since the 1940's researchers have used radiocarbon (Carbon-14 ... However, radio carbon dating is only accurate when testing fossils less than 100,000 years old. For anything older, tests need ...

This new estimate was established by dating Ruppia cirrhosa seeds found within the footprint fossils through radiocarbon dating. This process measures the deterioration of specific carbon isotopes ...

Thanks to radiocarbon dating of sediments surrounding the fossil, during the late Triassic period, about 225 million years ago. Also called the “Southern Cross Lizard,” the dinosaur was named ...
