You see them clearly on land, Godzilla is slightly larger and has hybrid design of the Legendary Godzilla and Heisei. Don't say he was higher in the water, I can list bullet points on how he wasn't.

I think those are enough reasons. Also Godzilla has to have a lot of nuclear energy blasted at him or seeping into his blood in order to do the spiral ray attack, which didn't happen (unless the mana beam was nuclear, but I doubt it)
 * He was in the same place
 * You can see his knees are at level at the same time
 * No other part of the water was like that and I doubt that a 10 meters in front of gamera would be so dramatic
 * Why wasn't Gamera risen, Godzilla and Gamera were in pretty in the same spot
 * Why could you see Gamera flying earlier being so much larger compare to the end
