Slyck Posted August 16, 2018 Share Posted August 16, 2018 This is my first fossil I need help on. Or maybe it isn't a fossil. I sent a picture to someone knowledgable in this area and he suggested this might be a psuedo fossil or concretion. I thought I would get a second opinion from you guys. I found this at the Lake of the Ozarks in Missouri in a wooded area not far from the water. Even if it isnt a fossil, I love this rock, especially the sparkly bits.

ynot Posted August 16, 2018 Share Posted August 16, 2018 Welcome to TFF! Need a couple of tests to see what it is, but it is not a fossil. Can You scratch a knife with it? Does it fizz when You drip some vinegar on it? 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Slyck Posted August 16, 2018 Author Share Posted August 16, 2018 I can do those, sure. Am I doing it directly the cone shaped part or just next to it? Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted August 16, 2018 Share Posted August 16, 2018 Try the white sparkly bits first then the red matrix. To see if the white stuff is calcite or quartz. If it fizzes it's calcite. Looks like an iron rich breccio-conglomerate to me, with quartz or calcite veins. 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
ynot Posted August 16, 2018 Share Posted August 16, 2018 At this point I think it is calcite with an iron stain on the outer layers. The tests will tell. Darwin said: " Man sprang from monkeys."

Slyck Posted August 16, 2018 Author Share Posted August 16, 2018 Thank you all for your patience! I'm supposed to be working so it took me a little extra time to do the tests. Nothing seemed to fizz at all. I tried a few conservative drops, then ended up spilling vinegar all over it. I used a knife to scratch at the red part and a dust came off. It had a iron odor which makes sense based on the posts. I searched for breccio conglomerate and have a rudimentary understanding. So I'm guessing that cone shaped part is just a broken stone instead of a dinosaur tooth or Native American trinket (which is the prevailing theory among the kids.

Slyck Posted August 16, 2018 Author Share Posted August 16, 2018 I'm sorry for getting that test backwards! Yes, I just tried and the white part made some scratches on the knife blade. Link to comment Share on other sites More sharing options...

No problem, the order does not matter. If it does not fizz and will scratch a knife blade it is most likely quartz. Darwin said: " Man sprang from monkeys."

Herb Posted August 16, 2018 Share Posted August 16, 2018 There seen to be some features along the bottom. Looks like Mississippian matrix but only guessing.

daves64 Posted August 16, 2018 Share Posted August 16, 2018 Is it me, or does it look parts of the one rock look like they're overlapping? Almost like the petals on a rose bud? 4 Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...
Bullsnake Posted August 16, 2018 Share Posted August 16, 2018 I believe Lake of the Ozarks is predominantly Ordovician; a lot of chert there in my experience. So, no dinosaur tooth! That oblong object is very curious, though.

Slyck Posted August 17, 2018 Author Share Posted August 17, 2018 First, thanks for all of your help far! It is fun trying to solve this mystery. I took some pictures with it damp to help show more detail. It appears to be smiling at me! Should I attempt to clean this up better? Also, I read somewhere that it doesn't take millions of years for an object to become mineralized. I hope I'm not wasting everyone's time over some antique litter.
