crabfossilsteve Posted July 17, 2019 Share Posted July 17, 2019 As before, hopefully one of the trilobite experts can identify this specimen. This is another unidentified trilobites I collected from the Ordovician Liberty Hall Formation near Blacksburg, VA many years ago. It is 7/8 inches long. I've been collecting at that site for since the mid 1980's off and on and this is the only specimen of this trilobite I've found. Let me know what you think.

Fossildude19 Posted July 17, 2019 Share Posted July 17, 2019 I could be totally wrong on this, but this looks more like a cephalopod to me, rather than a trilobite.

I thought the same thing before I even saw Tim's response. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Misha Posted July 17, 2019 Share Posted July 17, 2019 I am not sure I am on board with the cephalopod theory, I think I can clearly distinguish three lobes and I have never seen spines like those on the sides on any cephalopod Link to comment Share on other sites More sharing options...

If it is a trilobite, it would probably need more prep to ID, as it is extremely worn... 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

piranha Posted July 18, 2019 Share Posted July 18, 2019 The 'spines' are tapering in the wrong direction to be a trilobite. The 'axis' is a siphuncle. 3 Link to comment Share on other sites More sharing options...
crabfossilsteve Posted July 18, 2019 Author Share Posted July 18, 2019 Thanks for the comments guys, Yes it is not the best preserved. Although, I understand, I guess I'm still kind of hard pressed to see this as a cephalopod. Link to comment Share on other sites More sharing options...
