Find a lot of this mostly unidentifiable stuff at the beaches of Lake Champlain in Vermont, I know that Ordovician material is found here. I’m curious about the small circular fossils, they appear on many of the rocks around the beach, any ideas? They are tiny, about 2 or 3mm

Or both! I think I see examples of each in some of these pictures.

Could be a mix of the two, though I see primarily crinoid bits.

Edit: Beat me to it!:)

Thanks guys! I’ve wondered about these little things for so long. There are thousands of them scattered across some of the bigger rocks.

Must’ve been a beautiful sight, huge reefs of crinoids covering the Paleozoic ocean floor. Isle la motte is famous for its outcrop of the Chazy Reef. Your probably working with a later Ordovician formation, Geologic map says iberville formation.

looks like crinoid and tips of horn corals to me
