Why Most Fossils Are Incomplete

The video discusses the significance of Sue, a T-rex fossil, due to its completeness, having 250 of the 380 bones. Most dinosaur fossils are incomplete due to natural processes like scavenging, weathering, and geological upheaval. Sue's preservation was likely due to a debris flow, making it a rare find. The video explains the conditions that can lead to better fossil preservation, such as immediate burial and smaller size. Despite Sue's completeness, it is not representative of typical fossilization processes, which often result in less complete specimens. The study of Sue has provided insights into T-rex anatomy and behavior.
