Paleontologists Find Original Collagen in Fossil Bone of Edmontosaurus

Tuinstra et al. used attenuated total reflectance (ATR)-FTIR and cross-polarized light microscopy (XPol) supplemented by two mass spectrometry (MS) techniques to elucidate the question of collagen endogeneity in Edmontosaurus sp. fossil bone.

Detection of soft tissues (e.g., proteins) in fossil bones is a growing field of study and a new study led by University of Liverpool paleontologists contributes to the list of such findings. Using a combination of three independent analytical techniques, the authors show that collagenous protein remnants in some dinosaur bones are original to the fossils. Tuinstra et al. used attenuated total reflectance (ATR)-FTIR and cross-polarized light microscopy...
