Unique imaging of a dinosaur`s skull tells evolutionary tale
(PHYSorg.com Archaeology & Fossils)

Researchers using Los Alamos` unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done. The results add a new piece to the puzzle of how these bone-crushing top predators evolved over millions of years.
