Missouri State Dinosaur - Hypsibema missouriense Hadrosaur discovered in 1942 by Dan Stewart, near the town of Glen Allen, MO
The hadrosaurs are known as the duck-billed dinosaurs due to the similarity of their head to that of modern ducks.

Advances of the Ice Sheets
• Ice ages are characterized by glacial expansions separated by warmer interglacial intervals.
• Before the mid-1970's, the Pleistocene was divided into four glacial stages with intervening warmer interglacial stages.
• More recent investigations have shown that there may have been as many as 30 glacial advances over the past 3 million years (roughly every 100,000 years.)

Map of the upper Mississippi River basin the estimated pre-Illinoian (light gray), the estimated Illinoian (gray) and the Wisconsinan maximum limits of glacial expansion (dark gray).
The pre-Illinoian was the most severe: amongst its legacy was the changing of the course of the Missouri River to its present location, the scouring and filling of Northern Missouri topography, and extensive outwash gravels left to the south of the present Missouri River
