This is a nice sample of a crinoid die off aka hash plate from Oklahoma! Included with the MANY crinoid pieces, you can see a variety of other creatures that lived alongside these ancient sea lillies. These plates, like so many billions of fossils around the world were formed when ancient animals and plants were killed and then rapidly buried in sediment before decomposition or scavaging could occur. Subsequently, soluble minerals concentrated above the buried specimens percolate (think coffee) through the tombs of the buried creatures, replacing the specimen entirely (practically) through a process called permineralization. Fossils are like a 3D picture of the past. Enjoy this literal piece of history in your home!
