Primate brain photos
GAINESVILLE, Fla. — University of Florida vertebrate paleontologist Jonathan Bloch shows the preserved skull of the 54-million-year-old primitive primate, Ignacius graybullianus, and the virtual mold of the brain made from the skull in this June 5, 2009, photo at Florida Museum of Natural History at the University of Florida. The mold, known as an endocast, was made using an ultra-high resolution X-ray CT scanner that took more than 1,200 cross-sectional images of the skull.
