Jakuzi Posted December 12, 2016 Share Posted December 12, 2016 My girlfriend found this on the Sulphur River this spring and it looked interesting. No idea what it is. Now that I'm on here I thought you guys might be able to figure it out. Link to comment Share on other sites More sharing options...
JohnJ Posted December 12, 2016 Share Posted December 12, 2016 I think there is a good chance it is a stream tumbled, piece of calcite. It often forms in the faults of the Upper Cretaceous formations of Texas. You should be able to see broken facets under magnification. The layers of impurities erode out easier and leave a segmented appearance. 8 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
JarrodB Posted December 12, 2016 Share Posted December 12, 2016 I agree with @JohnJ it's calcite. I have one creek at NSR in particular that I find lots of it. Link to comment Share on other sites More sharing options...
tmaier Posted December 12, 2016 Share Posted December 12, 2016 On one side it looks like a cephalopod (photo 1), and on the other side it looks like a trilobite track way(photo 2). But, it seems to be a double sided pseudofossil, because it is neither of those things. From a distance, this rock says "Pick me up, I'm a fossil!", but he's lying. 2 Link to comment Share on other sites More sharing options...

Jakuzi Posted December 12, 2016 Author Share Posted December 12, 2016 The calcite would make sense. It does have a little sparkle to it. Guess I can leave it in the planter. Thanks for the help guys. Link to comment Share on other sites More sharing options...
FossilGuy1024 Posted December 13, 2016 Share Posted December 13, 2016 Totally agree, especially with the tabular shape of the piece. But, I have come across chunks of rudist bivalves that were so completely replaced by calcite it would be hard to tell the difference (relatively soft, white, and sparkly) if it weren’t for the cell structure.
