  1. Investigation of Source Material for the Proposed Jurassic – Cretaceous/ Tertiary Angiosperm Biomarker Bicadinane, in Parallel to Known Angiosperm Lineage Biomarker Oleanane Preliminary analysis of a suite of living flowering plants, that were treated to mimic burial and preservation, are found to have oleanane or des-A-oleanane. Oleanane has previously been reported in the fossil sediment and oil record and thought to be from flowering plants which this supports. Des-A-oleanane has also been reported but living sources were unknown. This is the first evidence of des-A-oleanane from flowering plants. David Winship Taylor, Indiana University Southeast, New Albany IN.   Our data show that biologically active oleanoids are the procurers to several diagenetic products including oleananes and des-A-oleanane. Parsimony MacClade reconstruction supports the hypothesis that oleanane is ancestral in angiosperms.
