What Would Actually Kill You in the Dinosaur Age

Could you survive the dinosaurs? You wake up in Hell Creek, 66 million years ago, in the last age of the dinosaurs. The T. rex is terrifying… but it's not what kills you. Mission Control gives you five survival rules for the late Cretaceous: from the river you can't drink (and the mosasaur that may be hiding in it), to the duck-billed herds and Triceratops, to the mammal with the strongest bite ever.
