What brachiopod is this?

[Utera]

I got this a while back with a little notecard with information about brachiopods in general, sadly, none of the information was specified to this specimen. Can anyone help me out on what genus this is perhaps?

Hi, you should show us photos of it from all its faces, like that :

 

 

Could you also give us a scale in inches or centimeters ? Because a lot of us are not from the US and don't know the size of that coin.

Also, it would help if you gave us the geologic age and where it was found if you have them.

Might be Pseudoatrypa or Atrypa, but given the encrustation covering much of the shell and lack of location / time period, that ID is "tentative".

The diameter of a dime is 17.91 mm, I'll make sure to put in a measuring tape next time.  I do not have any information on it. The notecard did not specify the location or age of where or when it was found.

I don't think you'll be able to get much farther than with what Peat Burns has said, unless you have the possibility to get the incrustation removed. As you may know, brachiopods existed from the paleozoic to the present day and there are thousands of species to choose from whose basic forms repeat themselves over time.

I'd agree with that. Looks like one of those Moroccan specimens that sat out in the weather a bit too long.

 

When you are trying to take your pictures, see if you can get a little farther away from the specimen and allow the camera to focus in a bit more.
