Bob Saunders Posted October 23, 2019 Share Posted October 23, 2019 Hi, I pulled this Crinoids fossil hash plate out of a hill today. I may have seen the mystery in Lake Michigan mud stone, but not raised up or nearly as large. Ideas? Thanks. item is 4 in x 2 5/8th x 7/8th thick. unknown item is 1 in long x 1/2 inch wide.

Rockwood Posted October 24, 2019 Share Posted October 24, 2019 It's most likely a worn fragment of a larger shell. Link to comment Share on other sites More sharing options...
