Dear Larry,
There might be a few more candidate names for the tube cluster as shown on
the photograph than suggested by Alexei (but he has a lot more experience
with fossils than I have). Hydroides is not the only genus that can be mass
forming like this, see ten Hove & van den Hurk 1993) but it is hardly
possible to see details on the photograph. Any chance to send me a piece of
the stuff? Alexei will be visiting me in Naturalis next month, so maybe we
could have a short look together.
gr.
Harry ten Hove
