Birds evolved from certain feathered theropod dinosaurs, and there is no real dividing line between birds and dinosaurs, except of course that some of the former survived the Cretaceous–Paleogene extinction event while the latter did not. These animals are common only in the deep ocean. Look at the pattern of spicules.
