Help with Fossil ID - Matoaka Beach 12/2/18

[rockfishmatt]

Hi folks - new to the forum. This is my very first post.  I took the advice of fossil guy and checked out Matoaka Beach today.  The temps were supposed to be warmer than usual.  A little rainy.  All of the rain we have had lately led me to believe there might be some wash outs along the cliff.  Found several Chesapecten, coral, big barnacles, and clams.  Below are pics of things I can't ID and was hoping for some help.  Two pieces look like bone.  Would love to get the forums thoughts!

Here's more pics of specimens I need help with.

First one is a slice of bone that has gone through a band saw ( butcher shop remenent?)

Second one, I can't explain the markings and the third looks to be some sort of shell, but no clue what is shaped like that.

Hopefully you will get some answers soon.

Ooops.  Found it buried under a pile of clay dirt along the beach. Oh well.

Here's another pic of the the one with the markings.  Maybe another butcher shop remnant?

The bone with the markings looks like it could be grooving from a spiral cut ham (or something similar).   Can’t say I’ve exactly seen that, but that is what I envision that looking like. Interesting.

The second item looks like a section of a water worn, broken shell, with some borings.

Here's another one that might of interest. A sedimentary collection of shells, sand, and clay.  There is a piece on the right side protruding that looks like a piece of bone. I don't have a drill so I can't take it apart.  Any thoughts?IMG_1318.HEIC

I agree with the others that the third fossil is a shell fragment, potentially from the genus of oyster Isognomoton (just basing that off the fluted structure).

The shell in question is a Miocene tree oyster, previously known as Isognomon maxillata. They are quite common, usually are broken, and frequently delaminate as they dry out.

I believe ClearLake pegged the bone with markings.  It seems to fit the same configuration as the spiral cut ham.

Welcome to the forum from sunny Florida. 3rd one I agree with others, a worn bivalve shell fragment still showing the ribs of the shell. At first glance it looked like mammoth tooth....wouldn't that been awesome.

Spot on. See: https://www.schnecken-und-muscheln.de/Bivalve-shells/Pteriidae/Isognomon-isognomum-PH-1-2-8-cm::2910.html?language=en

I agree!
