These pictures are of a somewhat unique and rare fossil found in the Louisville Kentucky USA area. The almost fossil bare New Albany Shale sometimes reveals a blue material that are the fish bone remains from the late Devonian Period. These fossils were found in the Blocher Formation of Clark County, Indiana, USA. The main pieces is about 2 cm in length. 

The fossils once belonged to Barbara Conkin(1928-2019) who taught geology at Jefferson Community College. Thanks to Kenny for taking these pictures.
