Is this a fossil clam mold?

[SCSeaGal15]

Can someone tell me if this is a fossil clam mold? Found at a barn in East Tennessee. Unsure where it was originally found but he thought he might have found it in a river in the mountains. It measures approximately 3.5" long by 2.5" wide by 1.25 deep. The  main body part is gray with some brown hints and the center band part is lighter whitish gray and also has some tiny holes at it's edges. Obviously I'm not an expert but I think it is interesting regardless. Help appreciated!

It's a cast of the interior of a bivalve -- a steinkern.

Thank you! Do you know what fossil period? Could it have been found in a stream in the Smoky Mountain region of Tennessee?

I haven't hunted down south yet so i can't tell by the looks of it, but here's a geologic map. Source: google image search

I disagree, from those photos. I've never seen a shell cast with quartz running through it and I think its a waterworn pebble with a quartz band running through it, although I could be wrong.

I think that's limestone with some calcite crystals, most places on the steinkern that matrix is worn away, but on the sides it has not.

That is interesting to consider Foozil. Certainly could be a water worn pebble with all the stream action of the Smokies. It has a shell look with both "side" above and below the line being really close to the same size and it tapers and has the general shape of a clam but I don't know. I like it but of course would like it better if it was a fossil!

 

Thanks for the map Whodaman! So interesting.

It is a petrified chicken burger!

Seriously- I agree with Foozil.

It is a mica schist with a quartz vein.

If it where calcite  the vein would be worn more than the  parent rock. 

 

PS You can see the mica sparkles in most of the pictures.

Ynot, Ha the man  got it from said he called it his "burger" rock! Funny you would call it a chicken burger. (:

Chicken is white meat and quartz is white rock.

I should have called it "chicken on rye".

Hu,

 

I am OK with Foozil too !

It's interesting Coco regardless. Thanks! Wanting it to be a fossil!
