For decades, the state dinosaur of Missouri was thought to be a sauropod. (Think of the long-necked Brachiosaurus made with breathtaking CGI in the 1993 film “Jurassic Park.”) But amateur paleontologist Guy Darrough’s recent discovery of a jawbone has set the record straight: Parrosaurus missouriensis is actually a duck-billed dinosaur.
“When they first started digging, they found the skull, the tail — which was a very large tail — and two arms and two hands. This last time, what they pulled out was the main part of the body,” Darrough said. “This is probably about a 35-foot dinosaur. It's a big boy.”
Parrosaurus remains have not been found anywhere else in the country. As Darrough puts it, making the discovery was akin to unearthing King Tut’s tomb.
When he realized the size and the scope of the newest specimen, Darrough said he called paleontologists from Chicago’s Field Museum, including the museum’s curator of dinosaurs, Peter Makovicky.
“We had been finding bones for quite a few years, but when we found this articulated skeleton, that's when we decided that we really needed more help,” he said. “We could tell there were some larger bones, and it really takes a lot of people to excavate a dinosaur. There's a lot of procedures.”
Of Makovicky, Darrough said, “He came down and looked at it and got very excited.”
Darrough joined Monday’s St. Louis on the Air to talk about the discovery and his work with the Field Museum to learn more about the excavation site in Bollinger County — where he’s hopeful of finding even more prehistoric evidence.
“Missouri is dinosaur country,” he said.
A full-size replica of a juvenile Parrosaurus missouriensis is now on display at the Sainte Genevieve Museum Learning Center. The 35-foot-long “big boy” the Field Museum has helped to unearth is probably a few years away from display, Darrough said.
