There is an Amphicoelias in this mod (Species: Amphicoelias altus), but Amphicoelias altus was only the size of a diplodocus (Or as wikipedia says: 18 meters long and 15 metric tons), Meanwhile Amphicoelias fragillimus was: 45-66.23 meters long (66.23 meters is from some random paleoart I found) and 120-190 tons (But the Highest I've seen in wikipedia was only 150 tons), Look I Know that Amphicoelias fragillimus is now Maraapunisaurus, but Amphicoelias altus never got bigger than Argentinosaurus so, @Giganotosaurus gaming Please take notice of this.
