late cretaceous unknown bone

[val horn]

My first thought was that this was another piece of turtle which is common in the area, but when I looked at it again it is seems to be curved in to many ways.  The "coral" growing on one edge is also unusual for the area-- i dont know what that reflects either.  I will much appreciate help in understanding what I am looking at.

Is that last pic a natural end. Maybe better focus if possible. Sharp close up of the coral would also be interesting. I recall some encrusters from the Severn along with the button coral Micrabacia.

hopefully these are sharper, i believe that the visible edges are actual  rather than artifactual but it is very hard to be certain with the  degree of preservation.

I'm not an expert, but what I'm seeing is a piece of weathered bone. The "Coral" on the edge the bone looks to me to be part of the internal structure of the bone, although it is odd that the holes are much larger.

skull bone has those big irregular holes. Also clams make round burrows in rocks and bone, shell etc in marine environments. I didn't know what the OP meant about coral until you pointed this out.

I still dont know what I have here, and maybe the preservation is so poor that I will never know   Can someone rule in or out turtle?  @jpc, @Fossildude19

I would not go any further in ID than... chunkosaur.  Unknown bone, unknown animal.
