Thank you for the reference. I will definitely read this paper. Also, here is a link to three photographs:

The first photograph indicates a larger tubular organism, which I think is some kind of worm. If you have any ideas about this, I would be grateful. The other two photographs show the smaller tubular organism, which I think is too small to be a worm. Foraminifera have been suggested as a possibility. Any ideas about this one?

Thank you,

You did not attach any images.  Consider microconchids.  See this excellent paper, which is available via direct search, on line.   Kind regards,  Roger Thomas

Is anyone on this list familiar with these? I do not mean serpulids. I have found some tubes that are substantially smaller than serpulids and I don't know what they are.
