Courtesy Mark RyanAs I've admitted before in these pages, I'm a big, big fan of the history of paleontology, especially that involving the infamous "Bone Wars" that took place in the American West during the 19th century. So I was real happy to hear that PBS is running a segment on its American Experience series tonight titled Dinosaur Wars. It's all about that legendary feud between paleontologists Othniel Marsh and Edward Drinker Cope. Several of the dinosaurs seen here at the Science Museum of Minnesota (and elsewhere) were first discovered and named by these two scientists as they raced to outdo each other in collecting and naming fossils. The show is scheduled for 8pm tonight (here in the Twin Cities), but as usual check your local listings for exact times in your area. If you can't wait until then or can't watch tonight, Rebecca Hunt-Foster over at Dinochick Blogs, gives a nice, lengthy synopsis of the program's content.
