The most important characteristics to consider when identifying Index Fossils: ABUNDANCE: To best allow paleontologists to correlate rocks with other rocks found at locations far apart, it's important that the index fossil be very widely distributed across a vast geographical region.
Fossilization. There are two major types of fossils-body fossils and trace fossils. Both are the remains of living organisms. Body fossils reveal the body structure of the organism while trace fossils reveal the activities of these organisms. The process of fossilization is called taphonomy.There are three main components.First, there is the death of the organism.ody fossils reveal the body structure of the organism while trace fossils reveal the activities of these organisms.
