John C. sent his thanks for helping to identify his USMC ring and wanted to especially thank Sherry, who came up with the answer.
He sent the following picture and said, Here is What happens with discarded fishing line ,This turtle washed up at wabasso beach in 2010 ,It looks like heavy test 80 or a 100 pound ,I think it's from long liners, But I'm not sure .

You probably know about Vero Man and what that is all about. It all started when a local collector noticed carvings on an old fossilized bone. I've found what appears to be shark bite marks on Dugong and other bones, but just the other day I picked up a vert and later noticed what appears to be bite marks on it (See below.). Of course that is nothing scientifically significant. It was just interesting to me, and goes right along with an article I was going to post today anyhow.

The International Business Times reports that scientists have developed a method to analyze the marks on animal bones recovered from archaeological sites. The shallow marks left by stone tools are often “V” shaped, while those made by trampling animal hooves are usually “U” shaped. The new technique, which employs 3-D imaging, shape analysis, and Bayesian statistics, was shown to identify butchery marks made by volunteers with stone tools 88 percent of the time.
Here is the link.

I was talking to somebody about beach and wave angles. I often talk about the beach like it runs north/south, which is seldom the case. As you can see from the map above, the Treasure Coast runs more to the northwest, while south of Palm Beach it is more north/south.
On the Treasure Coast it takes more of a northerly direction to get that slicing action that causes erosion. If it is just a little to the north, it will actually be hitting most of the beaches pretty straight on.
Of course the coastline is not straight and there are many curves or bends. That means that the waves will be hitting at a different angle as you go around a bend. Before you get to the bend you might see accretion, but when you get around the bend you might see erosion. The angles change.
Beautiful day.
I'm planning some experiments that will demonstrate some important things, but I don't know if I'll get it done by tomorrow.
Happy hunting,
