How realistic is this mass estimate? After all, it hasn't changed since the 
times when "*Brontosaurus*" was considered a camarasaurid. All those ancient 
books for children give it 30 t! Sure, *A.* was a lot more athletic than 
*Diplodocus*, so the 10 tons frequently estimated for the latter are 
probably too low, but three times that is a bit hard to believe.
