3-D scanning methods allow an inside look into fossilized feces

Coprolites are fossilized feces that give evidence of an organism’s behavior and often contain food residues, parasite remains and other fossils that provide clues to ancient paleoecological relations. Many of the inclusions in coprolites are delicate and fossilized soft tissues, which in many cases are more likely preserved within the coprolites than in other rocks. However, the composition, size and organization of the inclusions within the coprolites make them difficult to analyze. Classic techniques, such as looking at thin sections under the microscope or Scanning Electron Microscopy (SEM) require destructive preparation and can destroy the specimens. In a new study being presented at the annual Society of Vertebrate Paleontology meeting in Alberta, Canada researchers use synchrotron microtomography to understand as much of the content of the coprolites as possible.
