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.

Lunatia heros is a predatory snail that drilled holes in other mollusks' shells to eat the contents. One often finds hole that they left behind in the surrounding fossil shells. The shells of L. heros are variable, having more or less extended spirals, more or less globoular shape, etc. This specimen was donated to the Delaware Museum of Natural History.

I need help friends. A buddy of mine posted a pic of this on FB asking for help identifying it, no one could help. I loved it so I offered to buy it (which I did). This is all the information he could give me. My buddy's uncle died and left him a metal briefcase full of mostly old coins and a few other valuables. He lived in eastern Massachusetts. Items included really old papers, antique watches, coins as far back as the late 1800's and that thing. One interesting item was a fuel ration card from WWII... The intriguing part to me is how defined it is - it must be man made, right? Its
