Fundamentals of Earth Science: Fossils, Tectonics, and Time
Fossils and the Geological Record
Fossils are remnants of ancient life formed through fossilization, collectively creating the fossil record. This record, alongside rock and event data, helps reconstruct Earth’s geological history. The oldest fossils, around 3.5 billion years old, are a subject of scientific debate but contribute to our understanding. A distinction exists between “true” fossils, over 11,000 years old, and younger subfossils. However, a comprehensive record of all life forms is unattainable
