Tidgy's Dad Posted April 10, 2020 Share Posted April 10, 2020 Pretty sure that's Acanthothiris (often misspelled Acanthothyris) , Middle Jurassic, found in Europe, Central Asia and Morocco! I have one from England and one from Morocco. The productids contained hundreds of spiny genera, but otherwise spines are quite unusual. This one's a rhynchonellid, though, interestingly, the modern genus Acanthobasiliola is also spinose. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
nala Posted April 10, 2020 Author Share Posted April 10, 2020 Thanks Tidgy's Dad but my acanthothyris from Normandy looks really different Link to comment Share on other sites More sharing options...

Firstly, brachiopods can have a great difference of form within species and secondly, there are many species within this genus. I shall stick with my id for now, but let's see what the others say.

Tidgy's Dad Posted April 10, 2020 Share Posted April 10, 2020 I've just checked through the Treatise and even the updates, but can find nothing else even close. And it's Acanthothiris, not Acanthothyris, though it's a common mistake. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
nala Posted April 10, 2020 Author Share Posted April 10, 2020 Thanks Tidgy's Dad ?I though the color was typical of the paleozoic brachs,perhaps you are right,that's happen when the label is lost! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 10, 2020 Share Posted April 10, 2020 There is a possibility that it's a Productid from the Upper Palaeozoic, but if so, it's none of the ones that I'm familiar with, it looks all wrong, but there were some pretty weird forms. But, as I say, let's see what others think. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Shamalama Posted April 14, 2020 Share Posted April 14, 2020 I will defer to @Tidgy's Dad on this one as I do not recognize the specimen at all. It does not remind me of any Paleozoic form. Spinatrypa is rounder, and most Productids have a flat hinge line in my experience. 2 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.
