Using Campione and Evans equation, the specimen was estimated to weigh 60.4 metric tons, edging the very robust Dreadnoughtus estimates based on the same equation. The authors do point out that a new volumetric estimated Dreadnoughtus to be closer to 40 metric tons, thus Notocolossus may have been a bit more than that. Nevertheless, new doesn't necessarily mean better but the volumetric equation is very convincing, and thus maybe 42-45 tons would be a more accurate weight for the new Notocolossus. Reply
