113-Million-Year-Old Pterosaur Fossil Reveals What Flying Reptiles Ate

Grice et al. integrate organic geochemical analyses with high-resolution micro-mineral imaging of a three-dimensionally preserved Cretaceous pterosaur wing phalanx from Brazil to reveal steroid biomarkers and multi-stage mineralization pathways underlying its preservation. Image credit: Grice et al., doi: 10.1016/j.isci.2026.116199.

A 113-million-year-old pterosaur fossil from northeastern Brazil has yielded rare evidence of soft tissues, organic molecules and chemical traces of a diet heavy in fish and cephalopods such as squid or nautilus relatives.
