Not to mention CM 3018, the holotype, would be about 40 tons 
And OMNH 2162

Apatosaurus (and also Brontosaurus, I guess) where short but very robust dinosaurs. I am not surprised that they had such a big weights. Interestingly, the longer but much lighter build Diplodocus weighed about half of what Apatosaurus reached.

Thanks for sharing.

True! Apatosaurus is a VERY solid animal; I'd in fact say the difference between Diplodocus and Apatosaurus is like the difference between a spoon and a twig.
At 21 meters, Apatosaurus is 20 tons. Meanwhile, Diplodocus is 20 tons at 34 meters. And at or near length parity (say, the big 34 meter Diplodocus that was thought to be Seismosaurus vs the OMNH 1331 or OMNH 1329 Apatosaurus), the difference is immense - 20 vs 95 tons. 
In and of itself, Apatosaurus is a pretty big animal overall - we have no mature specimens aside from OMNH 133 and possibly OMNH 1329.
So, I think a weight range of 20-95 tons is good. The mean is 57.5 tons, about the same as Sauroposeidon. Reply
