paleoman1234 Posted May 3, 2018 Share Posted May 3, 2018 Help identify please Found near black sea, republic of Georgia. Size. 4"×3"x3". Rock appears to have been split in half. Only have 1 half. The rock is very hard. To me it looks more like it was painted. Colors red, greenish black, Maybe 4 legged animals with horns and some kind of native plants depicting a seen. Outside surface of rock is smooth and well rounded. Link to comment Share on other sites More sharing options...
Draconiusultamius Posted May 3, 2018 Share Posted May 3, 2018 Perhaps the exterior view would be helpful. It could also be a pseudofossil with manganese oxide. 3 Link to comment Share on other sites More sharing options...
Pemphix Posted May 3, 2018 Share Posted May 3, 2018 IMO no fossil or artifact it is calcite nodule with iron/manganese oxide (so called "dendrites"). 4 Link to comment Share on other sites More sharing options...
Fruitbat Posted May 3, 2018 Share Posted May 3, 2018 I must say that is one of the nicest specimens of manganese 'dendrites' I have ever seen! -Joe 1 Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...

Malone Posted May 3, 2018 Share Posted May 3, 2018 Very cool! The colors are great! Wonder what caused the colors. It seems like a clay base, with possibly manganese and chlorophyll. Link to comment Share on other sites More sharing options...

Rockwood Posted May 4, 2018 Share Posted May 4, 2018 I do not believe the original post shows dendrites. The shapes are to continuous with the rind of the concretion, and just flat not dendritic in shape. I think two separate materials or states of oxidation in the original concretion are the cause. 2 Link to comment Share on other sites More sharing options...
bone2stone Posted May 6, 2018 Share Posted May 6, 2018 This is one cool specimen!!! I would get back out there and try my best to find part two!!! Awesome find. Natural, and very distinct mineralization penetration. The pointy outline is unique to say the least. Jess B Just noticed "Black Sea" in southern Georgia? I am presuming, not Georgia in the U.S.? My suggestion of getting back out there is a little far fetched if you are in Chicago. Link to comment Share on other sites More sharing options...
FNG Posted May 6, 2018 Share Posted May 6, 2018 That is amazing. The first thing that I thought of was an ancient map of a coastline or inland sea. Link to comment Share on other sites More sharing options...
paleoman1234 Posted May 23, 2018 Author Share Posted May 23, 2018 Can dendrites form on a curved surface? I've attached a side view photo to show the curve. Note: The edge is razor sharp on one side. Also the areas with colored patterns, under the microscope look more like a painted surface rather than crystalization, although I'm no expert. Is it possible it could be some ornate ancient cutting tool or blade? The stone is very hard. Some food for thought. Link to comment Share on other sites More sharing options...
ynot Posted May 23, 2018 Share Posted May 23, 2018 The dendrites will form an any surface available, regardless of shape. Dendrites can be 3 dimensional but are often flat (because of available space). Many rocks will break to a sharp edge. Your rock is not an artifact. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF. Link to comment Share on other sites More sharing options...
