Of the A. altus only one of the neck vertebrae was found. So? Of many dinosaurs there is only one bone found, the rest of the dinosaur is based on his family. But this time it is a different story. If you scale the vertebrae of it to the vertebrae of another diplodocid, the whole dinosaur must be... 58 METER AND WEIGHTED UP TO 122 TONNES! That is about the double of a diplodocus! The name means doubly hollow. More than that is almost every info. #amphicoelias #giant #vetebrea
