I attended a very nice seminar today, given by Dr. Paul Taylor 
(Natural History Museum, London), suggesting that so-called spirorbid 
tube fossils from the Devonian-Triassic might actually have been 
produced by a lophophorate.  Based on tube structures, it appears 
that spirorbids did not appear until the Cretaceous, rather than 
extending back into the Paleozoic. The paper upon which Paul's talk 
was based is:

Taylor, P.D. & O. Vinn.  2006.  Convergent morphology in small spiral 
worm tubes ('Spirorbis') and its palaeoenvironmental 
implications.  Journal of the Geological Society, London, 163: 225-228.
