THE LAND BEFORE MINES

CHISHOLM – A new exhibit opened at the Minnesota Discovery Center in Chisholm in March. This temporary exhibit examines what lies underground on the Iron Range—besides its iron ore. There were marine reptiles, dinosaurs and so much more.

“Millions of years before mining began, the Iron Range was at the edge of a large seaway. This seaway formed deltas, rivers, swamps, and lagoons throughout the Mesabi Range,” an introduction to the exhibit reads. Dinosaurs and other marine life roamed the ancient waterways.

“In the summer of 2015, paleontologists uncovered a 90 million year old fossil claw at the Hill Annex Mine in Calumet, MN. The shape and size of the claw indicate it was a two-legged carnivore from the dromaeosaur family. Dromaeosaur were small raptors (about 6.5 feet in length) and had a bite three times as powerful as velociraptors!”

This temporary exhibit ends Aug. 19, 2018. These photos are just a small taste of what you will see and learn from this unique and interesting exhibit. Check it out before it’s too late!

During the Cretaceous Period (145-65 mya), dinosaurs and other marine life roamed the Iron Range.

An interesting tidbit from 90 million years ago: “A large ocean called the Western Interior Seaway effectively cut North American in two. Minnesota was right at the edge of this seaway. Nearly all of the Mesabi Iron Range experienced incursions by this seaway.”

The fossil of a dromaeosaur claw bone was found at Hill Annex State Park in Calumet. The fossil is now part of the Science Museum of Minnesota paleontology collection. Dromaeosaurs had feathers and were a very early relative of modern-day birds.
