Jurassic Brachiopod

Heya! These are a couple of brachiopods I have found in the Cotswolds, UK. They are from the Middle Jurassic, and were found encased in oolitic limestone. They are a triangular shape, and, on the first picture, you can see remnants of a hinge. The third picture shows two of these valves. I haven't done any prep on them yet, as I am unaware of their exact shape, and do not want to risk damage to the actual fossil, so there is visible amounts of matrix. If anyone could put me on the right tracks of identification, or perhaps give me a rough ID, I would be very grateful!

Come to the spring that is The Fossil Forum, where the stream of warmth and knowledge never runs dry.

Id is going to be quite difficult with just a weathered partial like this. There are an awful lot of terebratulids in the Middle Jurassic which are similar in form and can only be distinguished from each other when all diagnostic details are visible. Many species even overlap stages, so you'd have to identify the zone it was found in in order to narrow it down. I'd stick to Terebratulida gen. & sp. indet. until you can get more details on it, although Al Dente's suggestion is a good guess.

That seems smart, good plan!
