Hey all, My daughter and I were agate hunting in Oregon's North Coast Range, when I scooped this curious piece out of the river. These grooves or striations have me wondering if this may have formed against some type of mollusk fossil. I would know this mineral as a "seam agate", however I have never seen grooves/striations like this before in the chalcedony. Has anyone encountered anything like this before or have any thoughts. I'de be curious to know more if anyone has. Thanks!

I found this unusual finger-like fossil on a Tampa Bay beach in Florida. It's about 3 inches long by 1 1/4 inch wide. It has an oval indention with swirls on the end, that looks like an external bivalve mold. The finger-like piece has corallite markings on it. Is this a mold of a shell or a fossilized coral finger? Thanks!

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!
