Its unique nasal structure suggests adaptations for a lifestyle that included both land and aquatic environments.

The dinosaur known for having nostrils positioned near the top of its head, functioning like a natural snorkel, is the spinosaurus.

Because it is easier for a dolphin to get air from the top of their head since they only come a little bit out of the water. Dolphins do not have nostrils - just the blowhole on top of their head. It is up there so they do not have to exert more energy or get more out of the water to get air.
Whales, dolphins and porpoises have a blowhole, (or nostrils), on top of their head so they can breathe in and out when they are on the surface of the water. Since they are the only mammals that spend their entire lives in the water, and much of it underneath the surface, they are the only mammals to have a blowhole on top of their head. Most mammals have their nostrils in the front of their face, similar to human beings.
