Fossilomics uses MS to extract amino acid sequence information from subpicomole quantities of protein and peptide fragments that remain in certain fossil samples. The sequences are compared to databases and validated with search statistics and high-confidence sequences. The validated sequences can then be used to place the fossils on the evolutionary tree.
