Found on 'my' beach, beside Patuxent River, southern MD

1. By chance have you seen any oddly large clams shells in your river?

We now have invasive Asian clams in the Shenandoah(!), my friend and her daughter found several shells a few weeks ago and called the extension office to see what they were. They said the clams likely came in bilge water and made their way down here. The shells are surprisingly large and a dark grey color, some slightly bluish.

The shell is beautiful, I hope the turtle had a long and happy life.
