The skull of Daspletosaurus horneri and life reconstruction based on the texture on the facial bones.The face was covered by an extensive mask of large, flat scales, and regions of armor-like skin on the snout, jaws, and ornamental horns.combined with advanced scientific techniques to learn more about these ancient animals.Using the fossilized bones they find, scientists will often try to determine first how old the creature is. One scientific and is produced naturally in the atmosphere when cosmic rays collide with nitrogen atoms.When carbon-14 atoms subsequently combine with oxygen, they form carbon dioxide that gets absorbed by plants.When humans and animals eat plants, they take in carbon-14 atoms. Scientists have measured the half-life of carbon-14 atoms to be approximately 5,700 years.The laser dislodged radioisotopes and other relevant isotopes, which were detected and counted.They then used these measurements to estimate an age for the bone.
Thomas Carr, a paleontologist at Carthage College, in a press statement.
In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.
This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.
The carbon-14 it contains, though, continues to age of the creature by testing and analyzing its ancient, fossilized bones.
Since the half-life of carbon-14 is about 5,700 years, carbon-14 can only be used reliably to date objects up to around 60,000 years old.
