Plant-like animal (or animal-like plant) found in Upper Ordovician shale near Québec City (Canada)

Hey there Fossil ID. Reddit couldn't do anything for me so I came here for a chance of getting this fossils ID'd! Here are the main informations I can give you about it:

 

• It was found on a roadside shale cliff in Château-Richer, just north of Québec City (Province Of Québec, Canada);
• According to Québec Government geological maps, the specimen was found in the Upper Ordovician Lotbinière Formation of the Sainte-Rosalie Group (just on top of the Utica shale);
• Two trilobites and several (dozens and dozens) of graptoliths were found around it;
• There is a graptolith overlying the main animal/plant I would like to ID, if you look well (reverse "V" shape);
• The fossil is preserved as some kind of carbon layer, just like graptoliths normally preserve;
• The specimen is roughly 4 cm long, if you compare it to my (dirty) thumb.

 

Any hint will be greatly appreciated, thank you very much!

Welcome to the Forum.

 

This looks like a colony of Sphenothallus.

You sir got something here.

 

Thank you very much for your insight, I had no idea what Sphenothallus were before you mentioned it.

 

Glad I came here!

And congratulations on doing a great job of explaining the geology of where you found it.  Too many new members give us next to no information and expect us to be able to positively identify it.

Congratulations. That is a very nice find in that material. I don't think I've ever encountered even a whisper of it while hunting in that area, let alone Chateau Richer that is really just a shadow of its former glory.

Any ideas on the Graptolite ID?

Not a specialist, but Didymograptus?

It is a possibility. 

Graptolites are not my forté.

I'm pretty bad on graptos, so I'm no help.
