Angel Wing Shell ID

[paul monfils]

Hi.  Actually this shell is in a different family from the angel wing shells.  This family is commonly called Ark Shells.  There are similar species in various parts of the world, but assuming that this one was collected in your vicinity, it's scientific name is Arca zebra, and its common name is "turkey wing".  The one in your picture is not very well cleaned.  When fully cleaned they often show an attractive pattern of white and dark bands, which is where the name "zebra" comes from. The following page shows a variety of arc shell species.  If you scroll down you will find Arca zebra about a third of the way down.
