WHAT CAN THEY TELL US ?
Several different groups are interested in fossils for different reasons. Petroleum geologists often work with paleontologists, because a paleontologist can determine by the type of forams that are in a rock layer whether there will be oil present. Forams are also used by geochemists. These scientists are able to determine the fossil's age by ratio-isotope studies. This is done by measuring the amount of element, such as carbon, that remains in the fossil. Whether it is students in classroom or a professor in a lab, the small size and abundance of forams make them useful tools for anyone to work with.
