It looks like a mass of invertebrate coprolites to me.

Not like any coprolite I've ever seen

in the field or in images on the Net.

Invertebrate coprolites never get any Web time. That's why no one knows what they are...

This item looks kind of like some Ophiomorpha I have seen.

Images HERE.

On this webpage, if you scroll down to the Ophiomorpha statement, the link to fecal pellets shows a great pic of modern ones that look very similar to

the example posted in the original post.

Copied from the website ...

Vertical burrow reinforced by fecal pellets.

Today, Ophiomorpha is made by the ghost shrimp Callianassa.

Thanks for the info. I found it about 10 yrs ago on a fossilized beach, It is hard as a rock, even the sand is hard.

Here are some more examples.

From the Late Cretaceous of New Jersey.

And from the Pliocene of California (These are almost certainly from galatheid crabs)

But the burrows of callianassids (like Ophiomorpha) are not composed of fecal pellets. They are studded with shaped balls of sediment.
