Minnesota, despite being one of the most ancient states, geologically speaking, is actually seriously lacking in dinosaur fossils. Paleontologists know that nearby Nebraska and South Dakota both have notable fossil beds, but Minnesota took too much abuse from glaciers between dinosaur times and the present day, which obliterated any dinosaur fossils which were created here.
The only dinosaur fossils found in Minnesota? The scattered remains of a hadrosaur, a herbivorous, duck-billed dinosaur.
Minnesota is better known for even more ancient fossils, primitive sea creatures who lived in the ocean which covered Minnesota a half-billion years ago. Snails, trilobites, sea stars and brachiopods are common fossils to find in Minnesota, if you look in the right kind of rock. A notable hunting ground is St. Paul's Lilydale Park.
And, more recent fossils from the age of megafauna, creatures such as mammoths, mastodons, and sabre tooth cats, have been discovered in southern Minnesota.
The most reliable place to see dinosaurs and other ancient creatures is at the Science Museum of Minnesota, which has plenty of big, famous dinosaurs, like Triceratops, Stegosaurus, Tyrannosaurus Rex, and Diplodocus, as well as local Mammoth remains, and lots of other scary and fascinating paleontological exhibits.
The Bell Museum of Natural History has a much smaller collection of extinct animals, but does have a huge mammoth tusk which visitors are allowed to handle.
Barring teeny sea creatures, the human history of Minnesota is much more interesting than the ancient history. The land which is now Minnesota has been inhabited for millennia, and even urban St. Paul has places to experience history dating back thousands of years. Here's a list of historic places in St. Paul.
What about the rest of America? Here's an interactive map of dinosaurs across the US. As you may guess, most all of the other states have more dinosaurs than us. But, what does that matter? And remember that the Science Museum of Minnesota is one of the best in the nation.
