I’ve had this serpulid Serpula sulcata for a few months on loan from a good friend.
And now after closer inspection I’m quite sure I can see bioimmurations of the hydroid Protulophila gestroi Roverto similar to the picture below.
Also indicated by the red arrows in my photo below.
Thank you “Bill”….still lot’s more fossils to get through.
It’s not that often you get to say “there’s more to this than meets the eye “
Has anyone else rolled the above quote off the tongue before?
