The chimpanzee–human divergence likely took place around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.
Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. [59] Fossilisation is a rare event, and most fossils are destroyed by erosion or metamorphism before they can be observed. Hence the fossil record is very incomplete, increasingly so further back in time.
People first uncovered fossils around San Pedro High School in 1936. They were ancient shells belonging to snails and other mollusks from tens of thousands of years ago.
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...

The 3.48 Ga Dresser formation hosts microfossils of prokaryotic filaments in silica veins, the earliest fossil evidence of life on Earth, [70] but their origins may be volcanic. [ 71 ] 3.465-billion-year-old Australian Apex chert rocks may once have contained microorganisms , [ 72 ] [ 5 ] although the validity of these findings has been contested.
