Fossil or geological ?

[Denis Arcand]

I found a few things that I need help identifying ?

 

Quebec canada, Ordovician

[Kane]

I'm going with burrows. On the second image, there is a calymenid thoracic segment below the circled burrow, and a smattering of crinoid bits.

Top one it appears to have a trilobite head on the right side. 

[Kane]

That would be a brachiopod as the plications are visible.

That on the rightside of the top photo? Under the line drawn?

Yes. Zoom in.

I think he means just above the brachiopod. The purple line crosses through it.

Ah, possibly a glabella. We'd need to see that photo without the purple line to be certain.

Here's the second photo, zoomed in and without the purple line. As for the first photo, does anyone want to try guessing what it is? It looks like it could be a weird looking geological fracture to me.

Kane,  that isn't a trilobite head in that photo? Above the brachiopod?

Yes, I already pretty much confirmed that.

Looks like an area of matrix left from a concretion or nodule that had come loose.

[Mark Kmiecik]

The first photo may the wall of a burrow, or maybe not. I don't think there's enough there to venture a decent guess. If someone is familiar with fossils from that area, they may have a better chance of identifying it.

Thanks Kane, should I try to prepare it more, is there more of the trilobites underneath?

[Kane]

I doubt there will be too much more, as I suspect it is a moulted fragment.

Thank you all for your help, it is much appreciated
