Great images and very interesting 'thing' Do you have an idea of the approximate size? That might help someone to identify it.
Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

These look similar in size, shape, and color to sedge grass seeds (species info unknown) that I collected today alongside the pond. The tiny seeds were contained inside larger black husks, which I initially mistook for the seeds.

I did not see hexagonal patterning but didn't look that closely either.

So maybe a seed?

Can it be from the lake (Chicagoland) ? Google states that Prorocentrum is marine ....

Not too small for the seed ? Forgot to mention - it was almost transparent

Surprisingly, no. Using a stage micrometer, the grass seeds measure out to the same dimensions you noted: ~ 0.5 mm long x 0.25 mm wide. They are teeny tiny seeds, but not quite as pointed on the one end as your 'thing' is. I'm trying to see if they will germinate.

Your images are beautiful, btw.

Unless I have misread your location, you shouldn't have much trouble locating sedges along much of the lakeshore. There are large numbers of them up by Montrose Beach (bring the dog if you have one!!!).
