Jazfossilator Posted May 16, 2018 Share Posted May 16, 2018 Found at lake Champlain in Vermont, Ordovician-Iberville formation. I’m assuming the first bit is another type o bryozoan I’ve yet to have seen, and the second piece you can only faintly see the symmetrical counter part so I traced it to give a good idea of shape, is it some lining of a trilobite? Any information/ideas are welcome! 1.) 2.) Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 16, 2018 Share Posted May 16, 2018 What are the sizes of these items? Your first item may be a bryozoan, but there is a possibility that it could be a bit of the "lace collar" of a Cryptolithus trilobite. The only thing I can think of for the other item is the infilled imprint of the glabella of a Flexicalymene/Calymenid? trilobite? 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

The first piece is about 3mm at the longest point, and the other is 8mm long 4mm wide. Glabella imprint makes sense to me for the second piece, Thank you! Lace collar actually looks spot on to me I think youve got both of these right 1 Link to comment Share on other sites More sharing options...
Jazfossilator Posted May 16, 2018 Author Share Posted May 16, 2018 This thing still has me wondering, it appears to carry on for 3 loops at least, one of them the matrix has just fallen out Link to comment Share on other sites More sharing options...
FossilDAWG Posted May 16, 2018 Share Posted May 16, 2018 I agree, the first fossil is part of the collar of a trinucleid trilobite, likely Cryptolithus, and the second is a worn-down glabella from a calymenid trilobite, most likely Flexicalymene.

Tidgy's Dad Posted May 16, 2018 Share Posted May 16, 2018 The loops are the different parts of the glabella separated by the furrows that are deep in this type of trilobite. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Miocene_Mason Posted May 16, 2018 Share Posted May 16, 2018 I’ve never seen a trilobite lace collar, but the first item very much reminds of a spiny brachiopod fragment. Happy hunting, Mason Link to comment Share on other sites More sharing options...

I am not aware of any spiny brachiopods in the Ordovician of Vermont, but am pretty sure there are Cryptolithus trilos there.

That's a familiar figure! The 'loops' are glabellar lobes. 1 Link to comment Share on other sites More sharing options...
