“‘We only know about 29 percent of all dinosaurs out there to be found,’ said study co-author Peter Dodson, a paleobiologist and anatomy professor at the University of Pennsylvania in Philadelphia.” I found this quote to be surprising when I first wrote about it in 2006: Most Dinosaurs Remain Undiscovered. Yet we keep getting new discoveries announced (New Triceratops Ancestor – Nigersaurus the Mesozoic Cow!) showing, while I was surprised, the scientists knew what they were talking about.
