JamesAndTheFossilPeach Posted April 11, 2019 Share Posted April 11, 2019 This really cool trilobite came out of the wanakah shale of the Hamilton formation. 1 Link to comment Share on other sites More sharing options...
JamesAndTheFossilPeach Posted April 11, 2019 Author Share Posted April 11, 2019 It’s completely different from others we find Link to comment Share on other sites More sharing options...
JamesAndTheFossilPeach Posted April 11, 2019 Author Share Posted April 11, 2019 Is the coloring just minerals in the trilobite or is it something else. If anyone can tell me that would be cool. Me and Jay have a couple ideas about what it’s is but we’re not sure Link to comment Share on other sites More sharing options...
Kane Posted April 11, 2019 Share Posted April 11, 2019 Very nice. It is still Eldredgeops rana. They can appear slightly different, even within the same formation, on account of deposition and taphonomic processes. I have encountered them in various colours/shades from black, chocolate brown, tan, to grey. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
DevonianDigger Posted April 11, 2019 Share Posted April 11, 2019 To be clear, my ideas never involved it being a different species, lol. Jay A. Wollin Lead Fossil Educator - Penn Dixie Fossil Park and Nature Reserve Hamburg, New York, USA Link to comment Share on other sites More sharing options...

FossilDAWG Posted April 11, 2019 Share Posted April 11, 2019 I wonder if this could reflect a recently molted trilobite with an exoskeleton that is not completely sclerotized, versus an older individual. Alternatively, maybe the light colored one was closer to the surface, or more exposed to groundwater movement that leached the mineral content some.

DevonianDigger Posted April 11, 2019 Share Posted April 11, 2019 Definitely a good chance of the latter. It came out of extremely weathered rock on a creek shoreline. Jay A.
