Mystery brachiopod from the Kalkberg Formation


Nautiloid

Recommended Posts

I found this brachiopod today in Schoharie, New York. Its from the Lower Devonian Kalkberg formation and it’s by far the best brachiopod I’ve ever found. It’s super detailed and it’s absolutely perfect (except for some matrix that still needs to get cleaned off). I’m unsure of the species so any help would be great.

@Misha

Thanks!! Hopefully it’ll clean up well. The level of detail on the fossils from the Kalkberg formation is amazing!

Maybe one of these:

I don’t think it can be Howellella or Concinnispirifer as it has too many plications in the sulcus if I read the descriptions correctly. It looks more like Trematospira as @Misha has suggested. Wilson’s Field Guide to Devonian Fossils of New York shows a Trematospira perforata from the Kalkberg that looks very similar.

+1 for Trematospira sp.

 

@Shamalama has reported T. multistriata from the Kalkberg

I have to agree. Should have looked there first.  :duh2:

Nice find. :)

Those odd spirifeds and look-alikes are hard sometimes. I think the telling feature is not just the number of plications in the sulcus but the observation that they are all the same size.  Also there is no interarea. The beaks come to together tightly.
