Microscopic Food Remains (image) Uppsala University Share Print E-Mail Caption The fossil droppings were scanned using synchrotron microtomography. This works in a similar way to a CT-scanner in a hospital but with much stronger x-ray beams, making it possible to image the contents of fossils in three dimensions. The scans revealed many microscopic food remains including foraminifera (small amoeboid protists with external shells), small shells of marine invertebrates and possible remains of polychaete worms.
