Missouri dig site is home to at least 4 rare dinosaurs, and there could be more

The first tracings of dinosaurs in Missouri were found in the 1940s on the Chronister family's property when they were digging a well. In October, nearly 60 years later, another set of fossils from the same species were uncovered about 50 feet (15 meters) away.
