Evidence of preserved collagen in an Early Jurassic sauropodomorph dinosaur revealed by synchrotron FTIR microspectroscopy

Abstract

Biomolecules are rarely preserved during fossilization. Here, Lee and colleagues provide evidence of collagen preserved within the 195-million-year-old rib of a sauropodomorph dinosaur usingin situanalyses and suggest that haematite particles may have contributed to protein preservation.
