More like 0.5mm in size. The microscope was designed for circuits and i had to put my iPhone camera to the eyepiece (thats why the image quality is so bad).
I was looking for conodonts but found tentaculites, ostracods, chondrichthyan scales/teeth, placoderm gnathals, acanthodian scales, onychodont scale fragments, at least one good conodont, and a bunch of other things i couldn't identify.
As for macrofossils, no ammonoids but a lot nautiloids like brevicone oncocerids, a few orthocones, plus corals, stromatoporoids, brachiopods and bivalves. I call the rock layer GPF9, as it was the ninth layer I tested for microfossils in the mid Devonian Gravel Point Formation.
