Bois Blanc "Spine"

Recommended Posts

A few weeks ago I had posted some finds from the imported fill from the Bois Blanc Fm, and one in particular that resembles a trilobite genal spine. I went back today to collect and photograph it. It appears in a sandy matrix reminiscent of the Springvale Mbr of the Bois Blanc Fm., lower Devonian. It is a fairly substantial size compared to the usual array of brachs, etc. 

 

I'd have to rule out Anchiopsis since they do not have such a long genal spine. I can probably also rule out the thick lip of a Leptaena brach. Total length of visible part of the specimen is a little over 40 mm, but is likely a bit longer.

 

The brown "crust" usually signals the presence of trilobite in these rocks. I have a piece of the imprint with more of the brown shell somewhere in the house. 

 

Any help would be appreciated! Thanks. :)

Finally relocated the impression side that has some of the "shell" stuck to it. Hopefully this adds another clue.
