I never never see this before ?

[Denis Arcand]

What ancient creature is this? 

 

it has small bumps, no holes so i don't think it's a bryozoan?

 

I will appreciate if anyone can identify this little fossil for me.

 

Thanks!

Possibly a hypostome.

Thanks, that makes sense, it's just part of a trilobite

Given the texture, it may belong to Gravicalymene.

No, the hypostome is on the ventral side of the cephalon. Given the texture, it may belong to Gravicalymene.

 

Yes, thanks, I changed my post while you were writing this. at first i didn't understand the word hypostome, i thought it was part of the name, i found this image made it much clearer

 

Do you thing they is more of the trilobite in there that i could prep ? or is it just a small piece ?

[Kane]

I edited as well to ensure clarity in the exchange.  

 

There might be more, but judging by the general hash plate appearance, it may be more likely this is a moulted fragment.

A calymenid hypostome should have posterior spines.

My initial guess was a cheirurid hypostome, but the ornamentation on those is generally smooth (at least in the Neuville Fm; have never encountered a Ceraurus in the Nicolet). I reasoned it was just a bit too buried to show its usual calymenid splendour

Not saying I disagree with the suggestions above. But what about a Bellerophon type fossil?
