What is this?

[DeeMoji]

I found this in my friends “no scaping” rocks in his front yard. I have no idea where it comes from originally, but thought it was pretty cool. 

Any idea what it might be?

It reminds me of a tabulate coral but it looks slightly off. Probably the distance between the holes is what’s bugging me.

I think it is a worn coral.

Yes, could be worn coral. But i'm missing the typical coral-structures....

Maybe it could be kind of worn burrow from something like Teredo:

maybe a coral like Syringopora?

My first thought was coral as well but is it possible it could be petrified cacti?

Could be palm wood.

Calamophyliopsis coral ?

Here are mines or comparison :

The thought went through my mind too. It's hard to explain how the shapes could be expressed as voids this way though.

Could be palm wood. I have added a few pictures that look similar to yours.

Probably you don't realized that, but you forgot a "l". (Maybe someone would try to search in the direction you suggested.)

Nice specimens, BTW.

Thank you, sorry it's Caliamophyliopsis

To me it's more consistent with a colonial marine invretebrate, like a coral, than palm fiber because the proportions, preservation, and material are less convincing for a palm.

Ya, that sums it up pretty good.

I think, the correct name is Calamophylliopsis, Sopfie.
Specimens of this stony coral (Scleractinia) was reported from the Paleocene (Danian) of France.
