Well, it does bear a resemeblance to Godzilla, who is a reptile. And the sail is also found in some species of reptiles, such as the Spinosaurids and some extinct synapsids like the Dimetrodon and Edaphosaurus, along with some species of modern-day basilisk and iguana. That being said, however, there are also fish with sails, so its not a trait exclusive to reptiles. So it could very well also be a piscine trait.

As for mammalian...Well, its face do bear a resemblance to that of a marine mammal like a dolphin or porpoise, so I guess that's where the mammalian part come's in?
