minnbuckeye Posted February 17, 2018 Share Posted February 17, 2018 A Fossil Forum friend sent me a few Georgia rocks to split. They were full of trilobites and bits. I believe these are all Aphelaspis brachyphasis but I understand this site has other species as seen in this information : Locality 1 is an outcrop in Murray County. The matrix is mudstone and the researchers report “very abundant specimens” of Aphelaspis brachyphasis often as body clusters. Locality 1, Murray County: Agnostus inexpectans Aspidagnostus rugosus Glyptagnostus reticulatus Aphelaspis brachyphasis ; Could any knowledgeable person verify the identities of these trilobites. As I said , it seems like they are all A. brachyphasis but the HUGE size differences to the trilobites leave me wondering whether I am missing something. Thanks.

minnbuckeye Posted February 17, 2018 Author Share Posted February 17, 2018 It is especially the second to last picture that confuses me. They are TINY!!!! Link to comment Share on other sites More sharing options...
Kane Posted February 17, 2018 Share Posted February 17, 2018 I think the second to last picture contains A. brachyphasis as well. They can indeed come out very tiny! I have one that measures less than a half a millimetre, and that I could only make out better under the microscope. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 17, 2018 Share Posted February 17, 2018 Some lovely Aphelaspis there, I've got a few of these and I love 'em I think all the same species except, maybe, just maybe in the centre of that second from last piece, could that be an agnostid cephalon ? I can"t see it clearly enough 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

All a whole bunch of Aphelaspis. They're everywhere in the Conasauga! Every single fossil you see is a miracle set in stone, and should be treated as such.

Bobby Rico Posted February 18, 2018 Share Posted February 18, 2018 @minnbuckeye hi Mike beautiful trilobites and I love the contrasting colours of the Trilobites and the mudstone matrix cheers Bobby. Link to comment Share on other sites More sharing options...
