Klaus_Grizwold Posted June 12 Posted June 12 This seems to be some kind of fossil soup, I can see many kinds of aquatic fossils, and bore holes. My question is, is the underlying structure limestone, rotten and fossilized wood, or degraded bone? Or something else. Found along a beach ridge of Lake Agassiz in North Dakota.
Fossildude19 Posted June 12 Posted June 12 Looks like limestone or mudstone. The tubes look like the remains of stick/branching Bryozoans. I see one or two shell fossils, as well. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."
