RichW9090 Posted July 10, 2015 Share Posted July 10, 2015 (edited) Out of focus; no information as to where it was found or what its age might be. Sorry, but anything anyone says about this would be pure conjecture. Cant read the scale, so no idea if it is one inch, one foot or one meter in length. I will say this - Sinemys gamera it is not.

Auspex Posted July 10, 2015 Share Posted July 10, 2015 It appears to be the positive cast of an invertebrate's resting place.

Auspex Posted July 10, 2015 Share Posted July 10, 2015 Sinemys is a genus of L. Jurassic - E. Cretaceous turtle, known from China and Japan, so it certainly is not that.

RichW9090 Posted July 10, 2015 Share Posted July 10, 2015 Give us some information to work with here, Shane. We might could be of help, then. The plural of "anecdote" is not "evidence". Link to comment Share on other sites More sharing options...
billheim Posted July 10, 2015 Share Posted July 10, 2015 (edited) Shane, If this is from the Eastern United States, it looks to me like a burrow of a trilobite, called a Rusophycus.. It's considered an Ichnofossil (Trace Fossil). See this picture of a Rusophycus from the Cincinnati Ohio (USA) area from the Dry Dredgers web site. http://www.drydredgers.org/fieldtrips/trip200804/images/IMGP1677.jpg. Do a web search on trilobite burrows and compare the images you see to your specimen. Hope this helps.

Auspex Posted July 10, 2015 Share Posted July 10, 2015 The trace fossil Rusophycus comes to mind.

ZiggieCie Posted July 10, 2015 Share Posted July 10, 2015 I agree with Bill, a resting place from a trilobite. A good find. Also welcome to the forum. To help with fossil or thing, ID's; photo needs to be in focus, a size reference and a location of where found. 1 Link to comment Share on other sites More sharing options...
abyssunder Posted July 11, 2015 Share Posted July 11, 2015 (edited) Ichnofossil Rusophycus could be a good ID. "The Rusophycus is a large,bilobate resting trace,which separates mesially to reveal two longitudinal series of nodes (Figs.2,4,5).Rusophycus is normally attributed to trilobites (Bergstrom,1973), but rarely is the trace-forming trilobite found associated with the trace."
