Jurassic brachiopod ID

[nala]

Perhaps could somebody help to ID these bajocian brachiopods found last week in a Vendée quarry? Thanks 

the first on matrix,i think it could be Sphaeroidothyris with a not usual shape

The others?

I’m sorry, I can’t help with an ID. I just wanted to say those are really neat looking brachiopods.  I don’t see many Jurassic aged brachs, hopefully someone can help you with an ID.

Perhaps @Tidgy's Dad is familiar with this one.

Yes, the first one seems to be a Sphaeroidothyris sp. 

They quite often exhibit sudden changes in growth rates leading to odd shell shapes like this. Probably due to changes in food availability. 

The two more tear drop shaped ones on the left in the pictures seem to resemble Karadagithyris sp. The others may be this genus, too, but I'm not sure.
