Another driveway find. Is this a sponge of some kind or possibly and bone from dorsal fin? Kind of looks in the shape of the ulna i cant find any reference on what an isolated one looks like. Can bones be calcified like this? i have no idea.

Something covered in an encrusting coral or bryozoan, methinks. 

How big are each of the zooecia / corallites?

In that case probably, though not certainly, a bryozoan.

I think it's just as good if not better.

That's a nice piece and I would be trying to identify the species.:)

I don't know your formation, I'm afraid.

Unfortunately there is next to zero info on fort simpson formation. Its mid to late devonian shallow ocean. There is a species 

Fistulipora mackenziensis from canada mid devonian... and im on the mackenzie river. Thats my guess and im sticking to it. 

:DOH:

Sponge for me.

Demospongiae, Hadromerida. Probably family Suberitidae, genus Chaetetes.

Can you see Treatise online nº 58 Part E, Revised, Volume 4, Chapter 4A–B: HYPERCALCIFIED EXTANT AND FOSSIL CHAETETIDTYPE
AND POST-DEVONIAN STROMATOPOROID - TYPE DEMOSPONGIAE: SYSTEMATIC DESCRIPTIONS
