Spirorbis sp. worm tubes

Colony of an auloporid coral and
Spirorbis sp. worm tubes

Viewer Comments: (small spiral gastropod-like fossils)

I am fairly certain they are Spirorbis sp. worm tubes.
See page 539 , National Audubon Society's Field Guide
to N. American Fossils. I am pleased to report that these
tiny, filter feeding tube worms are indeed alive and
well, as I have quite a number of them attached to the
glass and gastropod shells in my aquarium.
