There are two ways to determine the age of a dinosaur fossil. One is called relative geologic time, which involves deciding whether one dinosaur fossil is older or younger than another. Geologists then measure the proportion of parent and daughter atoms present in the ash crystals to determine the crystals age.
How do they determine the age of dinosaur fossils?
Fossil age is determined using two methods, relative dating and absolute dating. In relative dating, fossils are compared to similar fossils and rocks, the ages of which are known. Absolute dating, on the other hand is used to calculate the precise age of fossils through radiometric dating.
How old can a dinosaur fossil be?
The fossils yielded radiocarbon “ages” between 9000 and 40,000 years (Dahmer et al., 1990; Fields et al., 1990). Since then, YEC authors have submitted several more Mesozoic fossil samples for 14C testing. All have had enough 14C to yield radiocarbon “ages” between 9000 and 50,000 years.
Can we make Dinosaurs?
Recent studies show DNA deteriorates and ultimately disintegrates after about 7 million years. Dig up a fossil today, and any dino-DNA within would have long since fallen apart. That means, as far as scientists know, and even using the best technology available today, its not possible to make a dinosaur from its DNA.
How old is the shell fossil?
What is a Fossilized Shell? One of the most common samples of fossils include different types of fossilized shell, these are also called ammonites, which are fossils of coiled up shells. These kinds of seashell fossils are from animals that lived in the sea between 240 and 65 million years ago.
