Help identifying inherited points

[Woodbooger]

Hey guys, I’m new to the artifact section of the forum so please go easy. A while back I acquired these arrowheads etc. that have been passed down throughout the family and I’m just getting around to ask for help. Originally found well over 100 years ago in a cave on private property near Endless Caverns in New Market, VA. I’m Very interested in knowing what the brown triangle shaped stone is. It has a carved groove and looks to also have a small indention on top. Thanks for the help, and let me know if you see anything else good in the pics!

Hey neighbor! Beautiful part of the world you live in. Nice pieces. I think the grooved one is a "net weight" used for fishing. It's a little bit small, but has the right shape.
