Thanks For Looking, I Have Only Been Hunting A Few Months and Have Learned A Lot From You Guys, I'm Wondering About These Holes, They Are Larger on One Side Than The Other, Os That How You Know That They Are Worm Holes ?

Thanks Again......

Not worm holes, similar... Gastropod predation. Your holes look like moon snail predation. Predatory shellfish drill holes/rasp holes into other shells to feed on them. This usually leave one hole.

Sometimes you will see lots of holes when boring sponges like Cliona sp. use acid to digest the shell and leave them looking like a sponge of holes. They don't eat the host shell, just live in it. Some places are INFESTED with Cliona.

Gastropods (snails) make a one sided beveled hole and usually in the right spot to kill and enter/eat the animal, like on the top of the umbo on a small clam. These look like beads.

Boring sponge holes are straight sided tube-holes and are usually much smaller and more numerous. Interesting enough, some artifacts were made using Cliona damaged shell....likely artistic....

Where is Reaper? He loves this sort of a find. Lol! Nothing wrong with imagination SA. If not for those of us who see the deep, and could care a less what people think of our visions, few technological advances would have ever taken place. Look at some of my older post. You'll see I have a wild imagination as well. However, a time comes when we must keep our visions to ourselves. I am only telling you this for your own benefit. I love your finds!! Others.... Well.... Not so much.

Good post Tom.
Well.. it is a "shell thread" figure I will post a few examples.
It takes time and patients to get to know the difference.
Tom has both as well as a admirable desire to be well educated on a common lithic in his area.. well done "Professor Shellman"




It's Also been my experience, That outside of the confines of a well-defined site.. without association to other artifacts.. the chances of finding small shell artifacts that may have been used as jewelry items are very very slim.
