There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I think I posted this earlier, but it was misscaled a bit. This is better.
Sue the Tyrannosaurus rex (FMNH PR 2081, 12.3 meters, ~8 tonnes) and the Dreadnoughtus holotype (MPM-PV 1156, 26 meters TL, 48.45 tonnes, still a juvenile). Now, even with this "extra large" Tyrannosaurus, we can see that there is a very large mass disparity here heavily favoring the sauropod. Even with the largest Tyrannosaurus, Dreadnoughtus is obviously the heaviest of the two - as a juvenile, it's 6 times heavier than the largest Tyrannosaurus. Adults would be even larger still.
Skeletals are by Hartman (Tyrannosaurus top and sideview), Dreadnoughtus discovery paper for side view, and palaeozoologist for Dreadnoughtus top view.
