Do you really think the brontosaurus acutally existed?

Yes, although the species was renamed "apatosaur." Why would you not think it existed? Don't tell me you're one of those "the fossil record is a conspiracy to damn us all to perdition" fellas.

The brontosaurus -- the most famous of all dinosaurs, the emblem for Sinclair gas and the model for the Flintstone's Dino -- never existed. O.C. Marsh somehow got some head's mixed up and what he thought was a new type of lizard was really just the previously discovered apatosaurus. So, order of discovery takes precedence over fame of name.

I just point this out to illustrate the dangers of depending too much on the reliability of the fossil record.
