Confuciusornis sanctus is the first beaked bird from the Lower Cretaceous of China. This Synchrotron Rapid Scanning X-Ray Fluorescence (SRS-XRF) image was scanned at the Stanford Synchrotron Radiation Lightsource (California).  The colours relate to the distribution of three elements and their concentrations: Green is zinc, blue calcium, and red copper. The image was created from SRS-XRF data by Dr Roy Wogelius (University of Manchester) and published in the journal Science (2011).
