Despite the popular exhibits in the world's natural history museums, most dinosaurs that existed remain unaccounted for, according to Swarthmore College statistician Steve Wang. But based on historic discovery trends, Wang estimates that 75 percent of those currently still unknown will be discovered in the next 60 to 100 years.

Wang and Peter Dodson, a professor of anatomy and geology at the University of Pennsylvania, combined a database of known dinosaur diversity and a statistical method to account for the incomplete fossil record. They estimate total dinosaur diversity to be at least 1,850 genera, an estimate on the low end since some dinosaurs may not have left any fossil evidence and will never be discovered.
