Bryozoan, and trilo piece?

Recommended Posts

Jazfossilator

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!

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.  :headscratch:

The only thing I can think of for the other item is the infilled imprint of the glabella of a Flexicalymene/Calymenid?  trilobite? :headscratch::shrug:

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 :)

This thing still has me wondering, it appears to carry on for 3 loops at least, one of them the matrix has just fallen outA19043B2-8349-45A6-95BE-168DDFE4D1E3.thumb.jpeg.269bac76e2d8f3feb088d1d4064032d8.jpeg

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.

The loops are the different parts of the glabella separated by the furrows that are deep in this type of trilobite.

Ah I see! So the bigger one is the same thing, thank you!

I’ve never seen a trilobite lace collar, but the first item very much reminds of a spiny brachiopod fragment.

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! :P  The 'loops' are glabellar lobes.
