 | | In fact, the rostral nostril appears to be the norm for reptiles, birds, and mammals, making it one of the few rules of anatomical construction among animals, says study author Lawrence M. Witmer of Ohio University. |
 | | Early paleontologists thought that the big sauropods were amphibious, and may have used an upward-facing nostril placed dorsally, or at the back of the bony opening, as a snorkel as they submerged themselves in deep water. |
 | | Witmer found independent confirmation of the dinosaur rostral nostril in the pattern of grooves and pits within the bony nostril, signatures of an intricate network of blood vessels in the nasal region. |
