Help with ID of this calymene trilobite

Recommended Posts

Hiya everyone.

I recently purchased this trilo. I’m in the UK.  Any help would be great.

My best guess at the moment for locality is maybe Malvern worcs.

Mmm.

It doesn't look like Wenlock Limestone, more like the Wenlock Shale, perhaps? 

The rock looks more Welsh to me.

Maybe it is Welsh the seller had no idea all I know is it looks quite like a calymene maybe it’s a Gravicalymene then?

Maybe. 

A close up of the cephalon might help.

 

It’s on its way here in the post so soon as it arrives I will take more photos

Well, the rock looks pretty hard to me. I expect air abrasives would be the way to go. 

I doubt my pin vice, pins and dental picks would do much good.

Yeah I tried a pin it didn’t do much would do more harm than good so maybe in the future send it to a preparer as I don’t have a air abrasive, any idea anymore on the species?

I still think Gravicalymene is possible, but I am often wrong. :rolleyes:

Thanks for the help I’m leaning a bit more to that as well now always a pain trying to identify any purchases when the seller doesn’t know the locality, would love to find a trilobite myself but there isn’t a lot of places in Scotland to find them other than girvan I think

Without locality info or a detailed view of the glabellar lobes a conservative label will suffice: Calymenidae indet.

At first glance I thought possibly C. blumenbachii (‘Dudley bug/locust”) but the matrix too dark to be Wenlock Limestone (Much Wenlock Limestone Formation).

Okay. I’m pretty sure it’s a Calymene. As for species, the only one from the U.K. that looks like that is C. blumenbachii. Looks very very like my two specimens, one from Wrens Nest and the other from Shropshire. Both Much Wenlock Formation. blumenbachii is only known from this Formation of Wrens Nest, Dudley and Shropshire.

The only info the seller had unfortunately was it’s from wales so unfortunately looks like I won’t be able to have a proper id for it in the future
