Finding the fossils of a large duck-billed dinosaur in southern Missouri is exciting enough, but a paleontologist who helped lead the dig believes there are many more in the same area. The latest fossils are a specimen of Parrosaurus missouriensis, first discovered at the site in Bollinger County nearly 80 years ago but not confirmed as a new species until the latest dig. Experts believe the plant-eating dinosaurs grew to around 35 feet in length. Last month, a crane hoisted a 2,500-pound chunk of remains from the latest find. The fossils will go to Chicago’s Field Museum for further research.
