Allmon received his doctorate in Earth and Planetary Sciences from Harvard University.
Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.
Radioactive decay is the term used for the process by which an unstable atomic nucleus loses energy by releasing radiation.
We know that elements can exist as isotopes, which means that their atomic nuclei contain the same number of protons but different numbers of neutrons.
The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.
After teaching for four years in the Department of Geology at the University of South Florida, Allmon became the Director of the Paleontological Research Institution.
