DinoClaw Posted November 18, 2013 Share Posted November 18, 2013 Hello everyone. My Flatmate found this fossil in a wood in North East France. Can anybody help identify what it is and what it may be from. Its roughly 24 centimeters in length. It seems to have a "blood groove" running from bass to tip. Any thoughts would be appreciated.

Fossildude19 Posted November 18, 2013 Share Posted November 18, 2013 Looks like maybe some kind of pinna type shell? I don't think it's a claw.

Auspex Posted November 18, 2013 Share Posted November 18, 2013 It looks 'shelly' to me, and somewhat resembles a Pinna bivalve.

painshill Posted November 18, 2013 Share Posted November 18, 2013 Yes, that's what I see too, and was just typing it when I got the "2 new replies" message. Some species have a central groove that runs the length of the shell (Pinna nobilis for example). You can see the growth striations of the shell at the fat end.

DinoClaw Posted November 18, 2013 Author Share Posted November 18, 2013 Intersting. I did wonder weather it might be a shell. Do you think its worth getting it dated? Link to comment Share on other sites More sharing options...
jpc Posted November 18, 2013 Share Posted November 18, 2013 and that texture on the wide end is not at all claw-like. Link to comment Share on other sites More sharing options...
painshill Posted November 18, 2013 Share Posted November 18, 2013 Intersting. I did wonder weather it might be a shell. Do you think its worth getting it dated? Do you mean carbon dated? What would you hope to get for your money? A date would satisfy your curiosity... but what else?

Auspex Posted November 18, 2013 Share Posted November 18, 2013 If we can identify the geology from whence it came, we can date it. Radiometric dating is rather expensive.

Plax Posted November 19, 2013 Share Posted November 19, 2013 looks a little flat and smooth for pinna, as auspex says, get the geo map (probably on line) for the NE France area and determine what formation outcrops there, someone familiar with that formation will be able to nail down an identity with that information Link to comment Share on other sites More sharing options...
elcoincoin Posted November 19, 2013 Share Posted November 19, 2013 i would suggest either gervillia or isognomon which are 2 types of mussles that would match the picture somehow. Size for gervillia would fit also . 1 Link to comment Share on other sites More sharing options...
old dead things Posted November 19, 2013 Share Posted November 19, 2013 Just for comparison. A pinna clam out of the Pierre Shale of the cretaceous in central Wyoming. Jim Old Dead Things Link to comment Share on other sites More sharing options...
