Trilobite pygidium?

[bmasur]

Hi everyone, 

I am very new to fossil hunting and am hoping to find some trilobites. I am located in along Lake Huron in Ontario, Canada on a rock formation from the middle Devonian period. I broke open a rock on my second trip and found this but I am not positive what it is. I think it could be a fossilized pygidium from a trilobite but i am really just guessing. I have attached to photos of the fossil, if anybody could help me identify it or steer me in the right direction that would be greatly appreciated. 

 

 Thanks.

A very nice Anchiopsis anchiops.

It would more likely be from the lower Devonian in the Bois Blanc Formation. Here is a similar piece from one of my hunting spots;

Wow! Thank you so much!
