Very nice variety.  You have a good number of the possible micro species from the Aquia Formation.  If you want to get some pristine micro teeth from the river sand, try seiving sand for  a concentrate to take home to search, in the slough pile areas in the Spring, right after the cliffs have sloughed.  Lots of pristine micro teeth from the cliffs wind up on the beach from the sloughing process and the wave action and moving sand hasn't had time to wear the teeth yet.

Lovely finds!

Very cool. How much material did you have to sift to find this number of specimens?

One of these containers 3/4 full. I carry in backpack. I believe about 15 sifts dumped in. I take it home and search.

That's a very good yield compared to the amount of material searched!

A great thing about micros is that even when you get a huge good haul like this one, they hardly take up much storage space.
