Giganotosaurus was the second largest theropod we have record of, second only to Spinosaurus. The largest specimens of Gigontosaurus had skulls nearly 1.65 meters long, and probably reached ~13-13.5 meters long and 7-8 tons.
Wasn't Carcharodonotsaurus, Tyrannotitan, Bahariasaurus, Oxalaia, and Sauroniops either a little bigger or incredibly close (if not equal) in size with Giganotosaurus? Because when I look at size scales between massive theropods Carcharodontosaurus seems to outweigh and be a little longer/taller than Giganotosaurus. I don't know Tyrannotitan's, Oxalia's, or Bahariasaurus' exact measurements but I think that the other three are incredibly close in size if not exceed it a little, I could be greatly mistaken though, but I do know that Carcharodontosaurs was roughly 45 ft. from nose to tail. Who knows, Giganotosaurus and Carcharodontosaurus could be equal in size or one could be slightly larger than the other.But anyway I love this rendering of this theropod, how long did it take?
Carcharodontosaurus is indeed right about the same size as Giggy, but it isn't complete enough to be sure if it was a little bigger, or smaller. All the others are significantly smaller, I doubt any of them exceeded 6 tons in weight.
