Understanding Fossils: An Introduction to Invertebrate Paleontology

: For an invertebrate to be well-preserved, it typically requires hard parts (like shells or exoskeletons) and rapid burial to protect it from scavengers and decomposition.

: Not all fossils are body parts. Trace fossils—such as burrows, tracks, and trails—provide direct evidence of ancient behavior and environmental conditions, like oxygen levels or water energy. Major Invertebrate Fossil Groups

: Taphonomy is the study of the transition of organisms from the biosphere to the lithosphere. This process includes death, decay, burial, and subsequent chemical changes known as diagenesis.
