"Nobody has looked at more fossil poop than he has," said Spencer Lucas, curator of paleontology at the NMMNHS - fully meaning it as a compliment.
Among the many surprising discoveries made as a result of coprolites is the fact, for instance, that duck-billed dinosaurs ate conifers; as in pine trees.
"Nobody thought that duckbill dinosaurs ate conifers," said Lucas. The lesson there, he said, is that there's only so much you can deduce about an ancient animal's diet from from teeth and associated fossils. "At the end of the day you have to identify the gut contents or coprolites to know what an animal ate.".
As for how "On The Origin of Feces" went as an event, it appears to have been a hit.
"One good thing about this is that it attracts kids," said Hunt, whose poop-laden table was near another where kids could match images of modern animal dung with various popular candies which they resemble. Kids won candy when they played the game and then impressed their parents by still finding it appetizing.
