In a 75-million-year-old wetland in Montana, the individual of Brachylophosaurus canadensis called "Leonardo" (far right) bellows a call warning his herd of an ambush by a Daspletosaurus torosus (background, left). A pair of Pteranodon survey the scene aerially while a Basilemys tutle observes from the water in the foreground. Watch for the upcoming documentary on the exciting research on this mummified dinosaur, entitled "Dinosaur Resurrection".
