Not many people know that Bird Pokémon are a subgroup of Dinosaur Pokémon, with their closest non-Bird Pokémon relative being Archeops (Archenus firstis). They are not the only Dinosaur Pokémon to have survived the end Cretaceous mass extinction event, but they are for sure the largest living subgroup. Bird Pokémon have evolved to conquer any environment, and many have adapted to live near water. Two subgroups (Freshwater Bird Pokémon and Seabird Pokémon) separately evolved several character (such as webbed feet) as an adaptation to swimming.
A new species of Seabird Pokémon, Hookrane (Shoresmus captainus), was recently described from various fossilized remains found in Unova. Several individuals have been found clustered in fossil beds, even more surprising was the fact that only one individual was in its last ontological evolution stage (possibly an alpha male that led the flock).
Several fossilized remains of ancient Coral Pokémon and Bivalve Pokémon species found nearby clearly indicate a coastal environment.
Fossilized remains of non-evolved individuals have been found alone and very far away from the aforementioned bone beds. They show a smaller thorax and they have been interpreted as females. It could be possible that females of the species lived alone and away from the coastlines, with males leaving the coast only during mating season.
