monkey puzzle ship worms

[Rockwood]

The tag on the box that I picked this out of (silver pick) identified it as, you guessed it, petrified monkeypuzzle wood with shipworm borings.

The ID seems right but it's such a beautiful piece I wondered if anyone has any further thoughts.

I believe these are burrows of clams, this kind of material is sometimes called peanut wood.

Very nice specimen, thanks for sharing. I am learning something new every day here on TFF!

And very nice specimens to find on the internet, could be Australian:

Peanuts made of algae that grew on trees in the ocean. Fascinating.

You forgot to mention the clams that were roasting and selling the peanuts.
