Hi everyone,
I was doing a beach cleanup on Sunday along the Port Tobacco River, & I noticed this little rock sitting next to an old beer can. It is 3 cm wide at it's widest point. The whitish grey color made it a challenge to photograph, so I added a slight wash to it. Any help with an ID would be greatly appreciated. I looked at many images of worms last night, but I didn't see anything with the same shape or length, & without knowing the age of the rock, I am not sure how to identify it. While it is whited out in the middle, when I look at it under a magnifying glass I can see that the horizontal lines extend through almost the whole length of the ovalish shape. This photo was magnified 2x. Thanks for looking!
