well actually Spinos are carnivores AND piscivores so they not
and T:Rexes are actually the biggest bc they the heaviest. they're not as long or tall but they have the biggesy organs and if u get a Spino, T:Rex and a Giganoto, cut them open and spread out their organs then the T:Rex will be the biggest. so T:Rexes are the biggest theropods
