    Influence of microbial biofilms on the preservation of primary soft tissue in fossil and extant archosaurs. by Joseph E Peterson, Melissa E Lenczewski, Reed P Scherer

    Published 2010-10-01
    “…<h4>Methodology/principal findings</h4>This study experimentally examines the role of microbial biofilms in soft-tissue preservation in vertebrate fossils by quantitatively establishing the growth and morphology of biofilms on extant archosaur bone. These results are microscopically and morphologically compared with soft-tissue extracts from vertebrate fossils from the Hell Creek Formation of southeastern Montana (Latest Maastrichtian) in order to investigate the potential role of microbial biofilms on the preservation of fossil bone and bound organic matter in a variety of taphonomic settings. …”
