Figure 3 in Mechanisms of soft tissue and protein preservation in Tyrannosaurus rex

Figure 3. SR-FTIR full spectra of isolated T. rex vascular tissue and chicken type I collagen (no treatment). All key bands for the identification of protein (Amide I, Amide II, Amide III) are present in the dinosaur tissue spectrum. The T. rex spectrum also presents a strong non-peptide carbonyl (C=O) band at 1739 cm−1 and a carbohydrate band at ~1010 cm−1.Published as part of Elizabeth M. Boatman, Mark B. Goodwin, Hoi-Ying N.
