I found this pottery shard today in a riverbed, and given that I am really bad in determining from which age/time period it could come from, maybe someone here can determine it.
I am unsure if it is visible in the second image, but the shard appears to be glazed a bit.
Edit: There also appears to have been black color applied to the potter (you can see some remains of it in the first picture under the edge/bulge (the part that is overhanging)
