I found this yesterday beachcombing At Otter crest, just after high tide " King Tides" This Beach is between depoe Bay and Newport Oregon.. I also found 8 agatised gastropods and 2 agatised mollusk's.. but my question is what this belonged to?.. I'm sorry I only had a centimeter or inch to measure with... So I chose the centimeter.. the closest thing I can find online seems to be a Vertebra.. it is completely mineralized and in the light glitters like Crystal. I rock hound quite a bit, but this is out of my privy... Lol can anybody give me more information?
