BigGuy Posted March 23, 2015 Share Posted March 23, 2015 (edited) Spring is here is the Ozarks. I had some business to take care of in Rogers, Arkansas. After lunch Billie and I drove a couple of miles to a weathered Karst limestone in the Boone formation. The site is easy access on the way to Beaver Lake. The Boone formation is: Early Mississippian Period Crinoids are the most common fossil found in the Boone formation, but brachiopods, bryozoa, mollusks, corals, shark material, trilobites, conodonts, and others fossils are known. The lower contact of the Boone Formation is considered disconformable in most places, but some researchers suggest a conformable lower contact with the Chattanooga Shale; the contact with the St. Joe Member is conformable. The thickness of the Boone Formation is 300 to 350 feet in most of northern Arkansas, but as much as 390 feet has been reported Edited March 23, 2015 by BigGuy 1 Link to comment Share on other sites More sharing options...
Auspex Posted March 23, 2015 Share Posted March 23, 2015 Dang, they look like rolls of coins! Is this how they weathered out, no additional prep?

Auspex Posted March 23, 2015 Share Posted March 23, 2015 That must have been quite a 'garden' in its day. 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

BigGuy Posted March 23, 2015 Author Share Posted March 23, 2015 (edited) Sure must have been. They are beautiful animals today but not as common as they once were. The crinoid garden must have truly been spectacular. At Falls of the Ohio State Park across the river from Louisville there is a recreation of an Silurian Sea. It is very beautiful.
