Missouri State Geologist Joe Gillman discusses the search for critical minerals in the Midwest.

The state dinosaur of Missouri was long thought to be a sauropod. Amateur paleontologist Guy Darrough’s recent discovery reveals that Parrosaurus missouriensis is actually a duck-billed dinosaur.

In this episode, we discuss the science behind Missouri’s many sinkholes and learn how the city of St. Louis was developed upon porous and uncertain terrain.

Earlier this summer, Missouri paleontologist David Schmidt and a small team unearthed a rare triceratops skull in the South Dakota Badlands. Schmidt describes what the excavation process was like and what he and his fellow researchers hope to learn from the bones of the dinosaur they named “Shady.”

A team from Westminster College in Fulton, Missouri, spent nearly two months carefully excavating the fossil, which measures about seven feet long and weighs more than 3,000 pounds.

States in the Deep South traditionally vote Republican in every presidential election. However, a string of "blue" counties curve through Mississippi, Alabama and Georgia. And the reason for this political anomaly seems to lie with ancient oceans and dead plankton.
