The Sea Rex was an enormous creature that was going to show up in Munch but never made it to the game. Most likely we will see it in future games. That is why we think the skelaton is a Sea Rex. But we arent really sure what it is. But one thing is common each picture the sketaton exists in the envirorments where eather paramites or scrabs reside. Even in AE with the concept art. Those are the valts where scrabs and paramites reside in.
So my guess is that this creature could be a delicasy to paramites and scrabs as odd as that may sound.
One can't kill it but a whole pack of paramites and a herd of scrabs may be able take this creature down. Almost like how small carniverous dinosaurs take out one Brontosaurs. Interesting!
