elz1582 Posted August 14, 2014 Share Posted August 14, 2014 Found in a shallow marine environment with a likely tidal influence. Found near tidal bars/beach facies. Link to comment Share on other sites More sharing options...
tmaier Posted August 14, 2014 Share Posted August 14, 2014 (edited) It is most likely a limpet. And not likely a fossil from the eocene. I'm pretty sure those color bands are his native pigments, indicating he can't be really too old. Edited August 14, 2014 by tmaier Link to comment Share on other sites More sharing options...
tmaier Posted August 14, 2014 Share Posted August 14, 2014 Take another phot of the back and below the shell. You are only showing one view in all photos. If its a limpet, there will be no hinge. Link to comment Share on other sites More sharing options...
elz1582 Posted August 14, 2014 Author Share Posted August 14, 2014 Heres some views from the side. information about the rock formation suggests it has ostreids, bivalves and gastropods present. Link to comment Share on other sites More sharing options...
Auspex Posted August 14, 2014 Share Posted August 14, 2014 I think it is a bit of bivalve.

tmaier Posted August 14, 2014 Share Posted August 14, 2014 I don't see a hinge line on that, so limpet is the best answer. Clams have a hinge that connects the two shells, but this one doesn't. Limpets have only one sheel and they stick themselves to rocks to cover the side with no shell. http://www.google.com/images?q=limpet&btnG=Search&hl=en&gbv=1 I might be wrong about the color. Did you find any other shells at the same site with that color? Did you pluck the specimen straight out of the formation, or did you find it loose near the formation? If you found it loose, then it may not be of that geologic formation. We call those foreign bodies, "floats", because loose objects can float around into other sites that they don't belong.

tmaier Posted August 14, 2014 Share Posted August 14, 2014 (edited) "a bit of bivalve"? Maybe the hinge line is broken off? Might be. Edited August 14, 2014 by tmaier Link to comment Share on other sites More sharing options...
Taogan Posted August 14, 2014 Share Posted August 14, 2014 It's a partial bivalve. Difficult to say which without the rest of it Link to comment Share on other sites More sharing options...
Herb Posted August 14, 2014 Share Posted August 14, 2014 looks like a piece of Pectin shell to me.
