Dear Annelidans,

Not a fossil-man myself but I thought this particluar beast looked extremely 
like the many Chaetozone sp. (Cirratulidae) tail fragments I have sorted 
through from deep-sea samples - and of course those present in shallow 
water. Particularly striking are the cinctures of alternating size acicular 
spines in the posterior region just as in Chaetozone setosa...  

Anyone more qualified than me prepared to comment on this? Of course 
the calcareous plates on the dorsal surface are not very cirratulid like I 
guess....! They say it is definitly not a polychaete.  

Reference below.
best wishes, Adrian
