historianmichael Posted July 27, 2020 Share Posted July 27, 2020 A few years ago I collected with the NYPS at a quarry exposing some Helderberg Group limestone. I failed to label some of my finds. I have a best guess on the trilobites but I was hoping to get some confirmation. I have struggled identifying a few of the brachiopods and a bryozoan and I could use some help with those. Any help is greatly appreciated. #1 - some type of bryozoan but I am not sure which one #2- ??? #3- ??? #4- Paciphacops logani? #5- Odontocephalus sp.? #6- Dalmanites pleuroptyx?

Rockwood Posted July 27, 2020 Share Posted July 27, 2020 Pretty sure the first one is a brachiopod. Link to comment Share on other sites More sharing options...
Jeffrey P Posted July 27, 2020 Share Posted July 27, 2020 First brachiopod looks like a flattened Leptaena rhomboidalis. The second I'm not sure about due to lack of identifying features, but probably an Orthid or Strophomenid. The third looks like Meristella. Can't help you with the trilobites except the one does not look like Odontocephalus. 1 Link to comment Share on other sites More sharing options...
historianmichael Posted July 28, 2020 Author Share Posted July 28, 2020 Thank you both for your initial thoughts. Hopefully these additional photos are helpful. Perhaps @Tidgy's Dad or @Peat Burns have some thoughts on the brachiopods and @piranha knows what these trilobites are. Could #5 actually be Synphoria stemmata? #1- I am still convinced that this is a bryozoan that has been broken, exposing the internal structure. I can certainly be convinced otherwise #2- ??? #3- ???

Tidgy's Dad Posted July 29, 2020 Share Posted July 29, 2020 A strophomenid brachiopod and an internal mold of an atrypid or orthid., I think. 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
