orockular Posted February 26 Share Posted February 26 Dug this out of estuary mud (fully buried about 8ft out from high tide line) in NW Washington. I’m a newbie, been scouring galleries trying to get some ideas, may just be a fascinating mix of rock but the dark stripe portions strike me as bone or shell. Weighs about 3-4lbs.

daves64 Posted February 26 Share Posted February 26 Looks like a sedimentary rock with fractures that have been filled in with some mineral. 1 2 Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 26 Share Posted February 26 Sorry, ... but I am not seeing bone or shell here. Looks to be possible banded chert nodule or some other geologic oddity. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
