I bought this from a box of unlabelled stuff that a dealer friend in the UK is gradually going through. Another friend IDd the coral as a Heliophyllum halli, perhaps from Hungry Hollow, which seems a good bet - I'm not very familiar with stuff from there though. Middle Devonian anyway.

 

It was the epifauna that really interested me, especially this nice patch of the bryozoan Botryllopora socialis. (It also has other bryozoans, hederellids and cornulitids.)

I'll second the Hungry Hollow Member for this piece as it is all too familiar to me. :D I've seen a few examples of Botryllopora socialis before, but this one is magnificent.

I agree! Looks very Heliophullym to me. The encrusted bryozoan is icing on the cake. Love this specimen! :wub:

The "yard-arm carinae" (the small branches attached to the septa, resembling the "yard-arms" on the mast of a sailing ship) are characteristic of Heliophyllum.  The coral and the epifauna are typical of the Hungry Hollow member at Arkona, but it could also have come from other Hamilton Group sites in New York.  I'd suggest "?Hungry Hollow Member, Widder Formation, Arkona, ON" as a locality.

 

I am quite fond of the epifauna on those corals.

I looked at some images of Botryllopora socialis that were identical to this and saw that they were from the Silica Shale. So it is another possilbility for its location.

A fairly rare Bryozoan from the Silica Shale at Sylvania is Botryllopora. It is found encrusting shells and other hard surfaces and has a star shaped look to it. Here it's covering part of a Strophodonta shell.

As would be select Devonian locations in New York, as Don said above. This bryozoan certainly got around! -- And no wonder as there were some intracratonic mixing between the Michigan and Appalachian basins during that time (particularly at the Chatham Sag between the Findlay and Algonquin arches).

Many thanks everyone for the confirmation and clarification! It's a grief to me that I can't hunt in this wonderful stuff myself. :)

If you ever have the occasion to visit, there'll be a large number of us who would be happy to show you around. :)

Seconded! 

That really is a superb specimen of H.halli and I love the epibionts too; that Botryllopora is to die for.

Thanks, Adam - I was rather overlooking the coral but it is a tidy one!

I agree with Adam! Great preservation on those.

It's classic stuff - we have no Devonian like it in the UK. The material from Devon itself mostly ends up cut and polished. :)
