Re: Fossils B/C
A piece of bone was found in South Dakota, and was analyzed to determine the age of the bone. A mass spectrometer revealed that the amount of C-14 was 6.25%.
How many half lives have passed?
Given that 1 half life of Carbon-14 is 5730 years, how long ago did the creature die?
While Carbon-14 dating is generally very accurate, list two of its limitations.
For older specimens, Potassium-40 is often used. Give the half life of Potassium-40, and the decay product.
In what US State is the Mazon Creek lagerstatte found?
About how thick is Beecher’s Trilobite Bed?
Which of the lagerstatte on the fossils rule sheet contains evidence that the area the lagerstatte was located in was once at the bottom of a lake?
