Molecular fingerprints resolve affinities of Rhynie chert organic fossils
Abstract
It can be challenging to identify extinct organisms with morphology alone. Here, the authors use non-destructive Fourier Transform Infrared Spectroscopy to determine the molecular fingerprints of eukaryotes and prokaryotes from the 407 Ma Rhynie chert fossil assemblage of Aberdeenshire, Scotland.
