Natural Histories

Take a stroll through a natural history museum these days and you’ll not only see dinosaurs, you’ll smell them.  Get a whiff of T-rex’s halitosis, his dinner leftovers, and, well, how should I put this – his droppings, too! In this hour of To the Best of Our Knowledge, museums that tickle your nose, and may turn your stomach.  Also, the giant beasts that once ruled North America.  And, an evolution explosion – deadly microbes run amok.
