Okay, I'll grant this is more a trick of perspective than anything else. But this photo of a brachiosaur skeleton towering over the puny humans is pure, petrified awesome. From here, hat tip to Dots in Deep Time. The blogger at the latter site, Ville Sinkkonen, points out that the little itty-bitty dino down there with the people is a mere diplodocus. The stats I'm finding seem to be maximums, which I don't want to quote. But suffice it to say, diplodicus was no weeny. Unless you compare it to a brachiosaur.
