American scientist Lawrence Witmer of Ohio University in Athens, Ohio has found that many images of dinosaurs may be wrong. For years, pictures of the ancient creatures have shown their nose openings near the top of the head. The new study suggests the dinosaurs’ nostrils were just above the mouth.
    Dinosaurs used their nostrils to breathe, smell and control their body temperature. The new theory could help explain how the huge creatures were able to survive by using their sense of smell to find food, a mate and possible enemies.
    Many of the early dinosaur remains recovered by scientists were from huge creatures called sauropods. Scientists believed that sauropods must have lived in water because their bodies were so huge and their necks were so long.
    Nostrils high on the head would have permitted the dinosaurs to breathe while partly under water. The discovery of a sauropod head bone in 1884 added support for this belief. The skull had a large hole at the top of the head.
    Professor Witmer found that the hole scientists once thought was a nostril in dinosaurs is just one part of the larger nasal passage. He found that the nostrils were farther forward and closer to the mouth. He says this new nostril position was hue for all dinosaurs.
