Please help ID this object I found on the beach

[Lisa Parsons]

I found this object on the beach near cape lookout after a storm.  It is very heavy.

Any ideas what this might be?  Thank you.

Interestingly shaped stone. Not a fossil in my opinion.

Interesting indeed! The only thing that keeps me from assuming this is just a worn piece of limestone/sandstone matrix is the apparent striated texture. Could well be the inner cancellous portion of a much larger bone with the cortex worn off by tumbling around in the world's largest rock tumbler (the ocean). If actual fossilized bone there will be little diagnostic information left with which to make any form of ID. Given the shape I considered worn coral colony but there are not indications of polyp structure.

 

 

Cheers.

Thank you, it’s also very porous but heavy.  A mystery I guess.  
 

Have a good day

This makes it extra interesting.

Are you able to compare the "heft" of your specimen with a normal stone of similar size (granite, limestone, sandstone)?

I was thinking sandstone, but I can also see the remote possibility that it's very worn bone.

I can try to find a stone of similar size and make a comparison.  I will update when I am able to determine this.

I seriously considered collecting a piece of rotted modern wood because it had a texture like this. It seems unlikely to be fossil wood, but maybe worth a thought ?

I saw an image of a petrified sea sponge that had similar visual properties.

To me it like like worn boneq
