Hello fossil enthusiasts! Is this a sea grass fossil? I recently found this stone while digging for earth pigments, on a hillside that was a former ochre pigment quarry. The hillside itself contains a lot of black and green serpentinite and lizardite, and lots of dense blue-gray clay. There is also ample hematite and ochre further up the hill. Oaks and grass thrive here, plants grow thick and fast on this hill. I don't know how to read USGS maps, but according to a USGS map I found (if I read it right), the site is in a pocket of "Alluvial fan and fluvial deposits (pleistocene)" (labeled "Qpaf" on the map) The rock was about three to six inches beneath a 45 degree angled surface, surrounded by black serpentinite and blue clay. If it isn't a fossil, what is it? Any insights are very welcome. Please let me know if the photos do not convey enough information, I will gladly supply more. You all ROCK! Thanks! Jesse

Found this hunting for shark teeth at a beach this morning. Sadly, no teeth. This however caught my eye. The one little “black coloration” looks like it has a stem and then extends out to a larger part, so maybe fossil seaweed? It might be just a rock. Let me know what you think please. Thanks!
