Absolute dating Amino acid racemisation Archaeomagnetic dating Dendrochronology Ice amino acid dating forensic science Incremental dating Lichenometry Paleomagnetism Radiometric dating Radiocarbon Uranium—lead Potassium—argon Tephrochronology Luminescence dating Thermoluminescence dating. Amino acid dating is a dating technique [1] [2] [3] [4] [5] used to estimate the age of a specimen in paleobiologymolecular paleontologyarchaeologyforensic sciencetaphonomysedimentary geology and other fields. Elsevier Inc. Amino acids, derived from indigenous protein residues protected by the skeletal hardparts of organisms, survive in most environments for thousands to millions of years. Sample preparation entails the identification, raw extraction, and separation of proteins into their constituent amino acids, typically by grinding followed by acid hydrolysis. Amino acid dating is a dating technique used to estimate the age of a specimen in paleobiology, molecular paleontology, archaeology, forensic science, taphonomy, sedimentary geology and other fields. In side-by-side tests, amino acid dating forensic science tooth protein analysis was more sensitive and reliable for sex determination than either DNA or looking at the anatomy of skeletons.

Their applications include dating correlation, relative dating, sedimentation rate analysis, sediment transport studies, [12] conservation paleobiology[13] taphonomy and time-averaging, [14] [15] [16] sea level determinations, and thermal history reconstructions. Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. This page was last modified on 23 Mayat Chinese Japanese Korean Vietnamese. Amino Acid Dating. The slight reduction in this [ clarification needed ] repair capability during aging is important to studies of longevity and old age tissue breakdown disorders, and allows the determination of age of living animals.
