Indiana limestone can be found in monuments and statues from Washington, DC to Florence, Italy. The same sedimentary limestone is also a rich source of Paleozoic fossils, namely crinoids. These crinoids were the "Masters of Indiana" during the Mississippian Age when Indiana was the bottom of the ocean. Our secret source of Indiana geodes also provides a range of different varieties of highly collectable crinoid fossils. Contact us to complete your fossil collection with a directly sourced Indiana crinoid. We hunt the site several times each year.
One of the benefits of the land we hunt for our famous geodes, beyond seclusion, natural formations, and crystal clean air, is the limestone exposure of the Mississippian Age and the Crinoid Fossils.
Indiana limestone, sedimentary stone, reveals the bottom of the ocean, when Indiana was the bottom of the ocean 360 to 320 million years ago. Indiana is one of the few locations in the world where the Mississippian Age is exposed, so as we trail ancient riverbeds for geodes, we are also turning over slabs of limestone seeking "the perfect crinoid". As our photos show, we have found many slabs of limestone covered in broken crinoids and an occasional crinoid head in rural Indiana.
The first native inhabitants of Indiana, the Native American Indians had discovered crinoid fossils, the crinoid stems. The crinoid stem is made up of tiny discs, that almost look like vertebrae. Little crinoid "discs" form the length of the crinoid stems. When the crinoids would die and break apart, the stems were scattered into the individual little "discs". When the crinoid stem discs dislodge from the limestone they look just like a stone bead. You could thread a wire or string through these crinoid stem "beads" and fashion them into a bracelet or necklace. In fact, Archaeological digs in Indiana show that the Native Americans did indeed use the crinoid stems in traditional jewelry.
We are also very proud of our Indiana Crinoid collection. In fact, one of our friends, a paleontology professor at a university on Long Island, New York thought our crinoids were so special and of museum quality that he now uses a collection of these Indiana Crinoids in his paleontology classes for educational purposes.
If you find yourself in Indianapolis, Indiana, we recommend stopping by the Indiana State Museum
for the impressive collection of Indiana fossils including limestone crinoid fossils.
