    This piece was excavated out of a block of matrix deposited in the Chesapeake Bay by a landslide. The shell was partially exposed in the water. The dark side was still in the matrix while the light side was exposed to the water. The pock marks on the light side are from modern barnacles which I removed during preparation.

     

    L. heros is a species with variation in shape. It may have a taller or flatter spire and the overall shape may be more or less globular.

     

    This specimen was donated to the Delaware Museum of Natural History.

    It's my understanding that the name Lunatia heros has been replaced by Euspira heros

    Here's a link to L. heros on the WoRMS (World Register of Marine Species) site. 

    Nice fossil!
