Mark22 Posted January 11, 2017 Share Posted January 11, 2017 Hello to all! I recently found what I think might be a fossil, however I am drawing a blank on what it might be. I found this while walking the shoreline of Table Rock Lake near Kimberling City, Missouri. The lake is +8 feet lower than normal pool and has left a wide swath of exposed lake bed. Table Rock is a man made lake used for power generation, built in 1954. The area that I found this fossil has several large shelves of rock with worm traces. I noticed these pieces while looking for lost fishing lures and thought that it looked out of place to the normal sedimentary rock in the area. There were some other pieces scattered in the immediate area, within a ~20' circle. I grabbed some of the more defined pieces and carried it home. Anyone have any thoughts on what it might be? Any clues on what to start looking for? Link to comment Share on other sites More sharing options...

Fossildude19 Posted January 11, 2017 Share Posted January 11, 2017 Hello, and welcome to the Forum. I'm getting more of a geologic vibe on these - maybe ironstone concretions. Maybe some more pictures from different angles will help.

Mark22 Posted January 11, 2017 Author Share Posted January 11, 2017 I'll be able to get a few more pictures when I head down to the lake Thursday. What drew my attention was the smooth lines on the what I assume is the fossil. The rougher outside I assume is conglomerate sand and mud. You might notice a greenish tint to the rock... It's been at the bottom of the lake for the better part of 70 years, so it has some algae buildup. I didn't have time to give it a good scrubbing the day that I found it. Thanks for the quick reply!

fifbrindacier Posted January 11, 2017 Share Posted January 11, 2017 I also think it is geologic. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux." (Antoine de Saint-Exupéry) "We only well see with the heart, the essential is invisible for the eyes." In memory of Doren Link to comment Share on other sites More sharing options...

Vieira Posted January 11, 2017 Share Posted January 11, 2017 My guess it's geologic too. Link to comment Share on other sites More sharing options...
Plax Posted January 11, 2017 Share Posted January 11, 2017 do I see both valves of an open pelecypod (pycnodontid oyster?) at 9 o'clock on the first pic? Some of the other bits look like agerostrea sans shells. Somebody needs to look at the Missouri geo map! Link to comment Share on other sites More sharing options...

They look like chert/flint chunks found in limestone formations commonly found in the Missouri Ozarks. Pieces of fossils are often found in them.
