@hawkeye10,
Alley Oop never really rode dinosaurs, but I sometimes try to calm down my need to be accurate and just enjoy the experience. I dont think that Spielberg was going to NOT produce Jurassic Park when he learnt that it is probably just bullshit for today.
Science, sometimes, can be really dull so the artists attempt to stoke it up a bit.
I enjoy the really well placed anachronistic goofs, like when, in a movie about ancient Rome, a centurion is wearing a watch, or in "Captain and Commander, where we can see a jet contrail in the background sky.
