I found a lot of threads that mention dinosaurs but none where this news article fits. (Joe/Clones, if you wish to merge this thread with another, have at it)

Dinosaurs are endlessly fascinating to me. I know there is NO evidence that human and dinosaur existences overlapped, but can you imagine??

CHICAGO (Reuters) - A fossil found in South Dakota is that of a never before seen species of dinosaur, a horse-sized plant eater with spikes on its bony flat head, scientists said on Monday.

"When my colleagues saw a CAT scan of the new fossil, they tore up their family tree diagrams and said, 'Back to the drawing board!' ... We never suspected such a creature existed," said paleontologist Robert Bakker.

Discovery of the flat-headed member of the pachycephalosaur family changes the view of dinosaur history during the final days of the Cretaceous Period 66 million years ago, showing that family trees were still evolving even as the entire dinosaur world was about to go extinct, the Children's Museum of Indianapolis said in announcing the find.

The nearly complete pachycephalosaur skull was donated to the museum by three amateur fossil hunters from Iowa who found it in 2003 while exploring the Hell Creek Formation in central South Dakota."
