*cough* _Bruhathkayosaurus_ *cough*

Oh, so _Bruhathkayosaurus_ is a real dinosaur. It's not a petrified tree trunk? :-)

There were certainly some big (really, really big) sauropods in the Late Cretaceous. (I have to say I don't know too much about _Bruhathkayosaurus_). However, there were more really, really big sauropods in the Late Jurassic, and more not-so-big sauropods in the Late Cretaceous. I was actually a little surprised by this trend.
