Kabaya Supersaurus

Supersaurus, found in 1972 , initial estimates outstripped all known brachiosaurids. Even if it weighed less than Brachiosaurus it still weighed as much as a blue whale. Due to the limited fossils the exact size remains unclear and whether it is more closely related to Apatosaurus or Diplodocus.
