A Ship-Sized Shark

Sometimes "they" talk about cloning prehistoric animals, a la Jurassic Park, and I think we all heave a wistful sigh about the possibility of seeing a wooly mammoth roaming around in the local safari-style zoo. Who wouldn't love seeing a fluffy version of Babar? A whole new line of stuffies would be launched, and teams would start sporting a new wooly mascot. So much fun! But is all extinction really so bad? My opinion is not so, in the case of the megalodon, or "Big Meg", a super-sized shark that would make a snack of a great white. Authors (a dad and daughter team of Flannerys) will ruin your potential sleepy time with tales of how this behemoth (probably) attacked and killed its prey, and how the poor saps watching from the shore probably vowed to stay away from the water forever. Maybe that's why they found that land bridge. Horror aside, it was fascinating. But I'd suggest reading another happy book along with it, if you value your dreams, that is.
