clamshells to their radiocarbon-dated ages to generate a scale showing which ratios corresponded with which ages. The researchers then looked at the D and L ratios of aspartic acid in the 250 Greenland clamshells to come up with the fossils' ages.

Amino acid dating is not new, but applying it to the study of glaciers could help scientists better understand the history of ice and climate change on Earth.
