A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. In many animals, the structure is called a muzzle , [ 1 ] rostrum , beak or proboscis .

The characteristic arched snout of Altirhinus was formed primarily by the nasal bones, and a similar structure is seen on the snout of the Australian Muttaburrasaurus. Many different functions have been proposed for the nasal arch. It may have housed tissues to cool the blood, conserve water, or enhance the sense of smell.
