Tiny trilobite pieces

[thelivingdead531]

Hey everyone! I have some tiny trilobite pieces that I found at Wren's Nest in Dudley, UK while on a hunt last year with @JohnBrewer. I was wondering if they are identifiable. The tiny single piece is 5mm long, and the piece on the small plate is 3mm long. Age is Silurian. Thanks!

Cute little trilo-bits.  

Maybe  @JohnBrewer or   @piranha  can assist.

Nice little trilo bits. 

The one on the left is almost certainly the Dudley bug, Calymene blumenbachii, which, as i'm sure you know, is the most common trilobite at this site and appears on the towns coat-of -arms.

The other one, on the right and in the second photo has rather smooth edges around the pygidial border and no obvious pygidial pleural ribs. The pygidial border is more reminiscent of Dalmanites, also common in these rocks but that genus has an obviously pointed pygidium and a spine, while this one is rounded 

So I think it is a worn Calymene , though many other species are found here I can't think of another match 

Mr Piranha ?

Oh, and I hope to go collecting with John one day, he seems a great guy and has kindly sent me two (not one but two!) parcels of Wren's nest material! 

Love it!

Thank you for the ID help! I looked at the pictures of Calymene blumenbachii online, and was wondering if the single guy could be that, but since it’s such a tiny fragment I wasn’t about to make that call. 

 

I’ve been to Wren’s Nest with John once, that’s when I got these little guys and quite a bit more of various items. He is a great guy and was very patient with me while I asked a bunch of questions about what I had found. It was a very fun trip and I hope to go back again soon.

Bingo @piranha! Perfect match. Thank you very much!

Cool finds, how long did you guys spend hunting there?

[thelivingdead531]

@LiamL I think we originally planned to stay for 2-3 hours, but ended up staying about 4.5 because we were having fun and finding all sorts of goodies lol.
