Testing the Hypothesis of Biofilm as a Source for Soft Tissue and Cell-Like Structures Preserved in Dinosaur Bone - Fig 8

<p>Overlay and fluorescent images of <i>B</i>. <i>cereus</i> (A, B), <i>S</i>. <i>epidermidis</i> (C, D) <i>B</i>. <i>canadensis</i> vessels (E, F) and <i>T</i>. <i>rex</i> vessels (G, H) exposed to antiserum raised against purified ostrich hemoglobin. No binding of these antibodies to either biofilm is visualized, but specific binding to vessels from both dinosaurs is seen. Scale bar for all images = 20 μm</p>
