JohnJ Posted January 31, 2016 Share Posted January 31, 2016 Wait, what? Comparative specimens as furniture... Do you have a matched "pear"? The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
New Members ValGal Posted June 13, 2016 New Members Share Posted June 13, 2016 (edited) What about this version found in tilled ground in TN? I find it hard to believe that it is only a concretion. Too many similarities to a peach and there used to be peach trees here at this 1921 home. Thanks for your input!

New Members ValGal Posted June 13, 2016 New Members Share Posted June 13, 2016 Hmmm...I attached one. Trying again. Link to comment Share on other sites More sharing options...
tmaier Posted June 13, 2016 Share Posted June 13, 2016 Those are concretions. The material is coarse, and I can't tell if it is sandstone or limestone. They are really beautiful and interesting. Link to comment Share on other sites More sharing options...
New Members ValGal Posted June 13, 2016 New Members Share Posted June 13, 2016 What would cause the concretion to form the "pit" that easily ejected itself when the piece as a whole was broken? The coloring (the dark stripe) also matches that of peaches around here. Too coincidental. Link to comment Share on other sites More sharing options...

The coloring (the dark stripe) also matches that of peaches around here. Too coincidental. There is more iron in the "pit" than in the surrounding area of the concretion. This can cause a area of weakness around the central part, allowing for a separation of the two parts. The colors are caused by the concentration of iron, which varies. You are comparing a rock with a modern peach. The modern peach is a product of selective breeding that has only been around for a few thousand years. This is not what an ancestral peach would have looked like millions of years ago. Also he meat of a peach is very soft and would not retain its shape when buried.
