Many seldom-classified fossil organisms are included, with a significant number of them classified at an advanced level. Individual phyla are recognized for the fossil genera Tribrachidium, Amiskwia, Dinomischus, Anomalocaris, Tullimonstrum, Hallucigenia, Opabinia and Pikaia.
We used specific scientific words to describe morphological features and other of organisms. Both the fossils and trace fossils can be analyzed in several different criteria. Special thanks goes to Kathleen Nester from the University of Calgary for helping me understand the morphological concepts.

Physical Characteristics

When Geologists, Paleontologists and fossil hunters search for fossils, they are heavily depend on the key identifiable physical characteristics of organisms. There is no such thing as a clear line between the difference between what is a fossil and what is not. Almost anything that is buried under the Earth can be considered as a fossil. However, the importance of the specimen to the Geologic time is very important. Let’s look at the physical descriptors.

After we established a sample is a true fossil, the next step is to determine its identity. There are several different methodologies in separating samples into Hierarchy of Life (K-P-C-O-G-S). Separation by physical characteristic is known as morphological division (or morphology).
