Molecular characterization of preserved tissues in a Cretaceous ankylosaur…and other digestive stories

Abstract: 

We used geochemical techniques to study the chemistry of soft tissues of an extraordinarily well-preserved Cretaceous dinosaur from Alberta, Canada. Analysis of the skin and armor plates revealed aspects of the pigmentation and the steroids present in the gut contents showed evidence of the prior presence of a microbiome. This talk will address the evidence that allowed us to make these assessment and other instances where steroids present in hominin guts can provide knowledge of value to archaeologists and health scientists.
