This one brought to you by the melancholy deaths of Chang and Eng Bunker, the sort of dinosaur book which proclaims “Brontosauruses had two brains”, and the notion that if you were to permit time travel to the past only for purposes that didn’t dick around with the timeline too much, dinosaur hunting in the late Cretaceous might get a look-in. Just don’t step on the rodents.
 The Internet informs me that
a) ‘Brontosaurus’ is an outmoded classification, and I probably meant ‘Apatosaurus’, and
b) It wasn’t the Brontosaurus that was thought to have two brains anyway, it was the Stegosaurus, and
c) The two brains theory has been thoroughly disproved anyway.
But apart from that, all good, eh?
