DaveinThailand Posted October 12, 2018 Share Posted October 12, 2018 Found this rock in stream bed gravels piled by dump truck next to Road #1013 in the Mae Win Sub-district area, about 50km south-west of Chiang Mai, Thailand. I've been rock hunting in the Intanon mountain area for five years, looking mostly for fossilized wood, but never saw a rock like this. It seems to be a fair match to Internet photos of fish dung ;-] Looks like there is a small bone fragment in the white colored area (see close up #122312) of the flat side. Appreciate any help with an ID> Regards Link to comment Share on other sites More sharing options...
Rockwood Posted October 12, 2018 Share Posted October 12, 2018 I don't see anything that convinces me of it being coprolite over stream gravel. Perhaps @Carl or @GeschWhat will though. 2 Link to comment Share on other sites More sharing options...
Carl Posted October 12, 2018 Share Posted October 12, 2018 I'm with Rockwood. That banded part through the "equator" is especially suspicious. 2 Link to comment Share on other sites More sharing options...
ynot Posted October 12, 2018 Share Posted October 12, 2018 Could be a hematite nodule with some quartz mineral (white) attached to it. Does it feel heavy? What color streak does it leave on unglazed porcelain? What is its hardness? 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

GeschWhat Posted October 12, 2018 Share Posted October 12, 2018 I'm afraid I'm with Carl on this one. While the material itself does somewhat resemble what I have seen in coprolites, the banding is a problem for me as well. On the bright side, it is an interesting rock. I would have picked it up. 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
abyssunder Posted October 12, 2018 Share Posted October 12, 2018 I agree with the others. I don't see it as a coprolite. It looks like a weathered banded silex (chert, flint, etc.), banded iron or other, with mineral crystals on one side. The west side of the country is full of igneous and metamorphic rocks.

DaveinThailand Posted October 13, 2018 Author Share Posted October 13, 2018 (edited) Thank you all for your replies, very informative and fun. To "ynot" . . the streak is white, it's harder than my knife blade and density is similar to granitic and many sedimentary rocks in the area. Here is what made me enter this for ID: 1. General shape and size. Yeah, it looks like poop ;-] 2. A pinch on one end and a rough (contact surface??) on the other. 3. Embedded in the white flattened area is what appears, under higher magnification, to be a 1cm long piece of bone shaped mineralization.
