Hello! Please take a look at this group of sub-millimeter grains and let me know if they belong with fossils. Micro gastropods ? Eggs ? Sand ? They are firmly attached inside a superficial fracture of this (presumed hornfels) rock. I brushed the rock with water and soap, washed it in vinegar, polished some parts of it - but the grains are still there. I suspect they are silicified, "glued" to the rock. All the black grains look kind of the same, including shape; the white grains also show a kinship between them, maybe. The black and the white grains seem to be all related, somehow. All the photos and a few close-up cinematics are in this album: https://photos.app.goo.gl/XRdjRisg8N4AeXTj7 The precise location where I picked up the rock is shown in the album (Braila county, Romania), could be an alluvial deposit. This camera and the app that I'm using are forcing a strong black/white contrast; with a loupe one can see more gray tones. Thanks!

I was given this piece and the only thing i know about its location is Morocco. It is about 5 cm wide and 4 cm hight and i think it could be a goniatite, but without certitude.
