Help Identifying this brachiopod #1

[Denis Arcand]

I need help identifying this brachiopod that I found in the Nicolet River Formation east of Montreal, Quebec.

Possible Atrypa rerticularis, couldnt be 100% , comparing Tims image with google images it looks quite close

I don't think so, Brian, as this looks more like a Strophmenid brachiopod.

 

Comparison:

 

 

 

 

More similar to something like Schellwienella radialiformis.

I don't know Ordovician brachiopods at all but agree with Tim @Fossildude19 that it's probably a strophomenid of which there is a bewildering array.

I stand corrected thanks guys , this brachiopod identification is a tricky business, i have one for id later myself

[Denis Arcand]

Thanks for the ID

It is definitely not Atrypa reticularis or any species of atrypid which are always astrophic ( don't have a straight hinge line.) For sure this is either a strophomenid or an orthid. Almost certainly a stroph. Which one I have no idea.

[Denis Arcand]

"Strophomenid" the name of the family? and Strophomenidae is the same, right ?

 

That makes sense. I checked it on the Atlas of Ordovician Life,. It can be difficult to find information when you don't know the exact name.

 

I’m still learning and identifying family is a good start. 

 

Thank you all!

Strophomenata is a class of brachiopods. People should call these strophomenates informally but actually usually incorrectly refer to them as strophomenids.

Strophomenida is an order within the class and only these are strophomenids in a true sense.

The Strophomenidae is one of many families within the order.
