Dino ID

OK, Last post. Santa got me a much better microscope and I was able to get a much better look at them.

I think that there is a combination of both large cell amphidiniums and prorocentrum.

Ordering silicates, but wondering if a UV may help at all if it's prorocentrum.

Definitely large cell, possibly prorocentrum. Same place I am. Can't tell if there is prorocentrum in there, but I also definitely have coolia. UV with the pump right near the sand did not help me. The joys of dinos.
