Sinistrofulgur contrarius(?Busycon contrarium)
Continuing with the mass posting to celebrate one year of the Sholesonian, we have this interesting fossil snail shell specimen. Normally I try not to pick up any fossils that don't have location data attached with them, they lose their scientific importance without it, but this one has an interesting feature that makes it a nice new addition to the Fossil Collection.
As for the shell itself, I've been told that it belongs to the genus Sinistrofulgur, which through some looking up seems to be now a part of Busycon. It's most likely Pliocene in age, meaning that this is a relatively recent fossil, only a few million years old. These snails are equipped to drill holes into their prey, usually bivalves, and eat the insides if they are successful. This particular shell is left-handed. And yes while snails don't have hands they can be either right or left handed. To figure out which a snail is hold it up with the point of the spiral up and whichever side the opening is on decides which-handed it is. If you mentally rotate the picture below 90 degrees clockwise you will see it.
