I found these today in a box of fossils from my collection that I had in the 1970's.  Other fossils in the box were mainly trilobites, crinoids and brachiopods.  At one time,  I had several thousand fossils, primarily from Ohio, Alaska and Utah.  I personally collected 100% of the collection,  so these fossils most likely came from oneof these states.      Any help would be appreciated.   Thank you.
