Mjsimet Posted December 29, 2016 Share Posted December 29, 2016 Found this in my grandfathers cabinet after he passed away. Supposedly found in Michigan. I have no idea what it is. Any suggestions/ help is appreciated! Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 29, 2016 Share Posted December 29, 2016 Welcome to the Forum. It is most likely a Concretion. Not an egg. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Rockwood Posted December 29, 2016 Share Posted December 29, 2016 This is a real stretch, but it seems like I've heard of something like this forming around foreign objects in the G.I. tract of farm animals. Might be worth considering. I can picture it being the sort of thing a grandfather might hang onto. Link to comment Share on other sites More sharing options...
Vieira Posted December 29, 2016 Share Posted December 29, 2016 Sorry, not an egg. Only a concretion. Link to comment Share on other sites More sharing options...
RJB Posted December 29, 2016 Share Posted December 29, 2016 Certainly not an egg, but being a concretion im now wondering what may be inside? RB Link to comment Share on other sites More sharing options...
GeschWhat Posted December 29, 2016 Share Posted December 29, 2016 Not an egg, but still very interesting. Because it seems to have inclusions, I wonder if it is some sort of steinkern (cast), rather than concretion.

Rockwood Posted December 29, 2016 Share Posted December 29, 2016 Enteroliths. Yup. It's a thing at least. They appear to vary quite a bit in appearance, but just from an image search I wouldn't rule it out. 2 Link to comment Share on other sites More sharing options...
abyssunder Posted December 29, 2016 Share Posted December 29, 2016 Not a bad idea, Rockwood. Here is an example of a big kidney stone... brrrr. BTW, @Mjsimet , was your grandfather a surgeon or doctor ?

Mjsimet Posted December 29, 2016 Author Share Posted December 29, 2016 No, he was a pilot. It was actually found by my mom when she was very young and he kept it all these years. She doesn't know what it is either. I appreciate everyone's input. Here are some other pics if it helps, top and bottom view. Link to comment Share on other sites More sharing options...

Come to think of it, I wonder if there are examples of fossilized kidney stones? Context is critical. Link to comment Share on other sites More sharing options...
abyssunder Posted December 29, 2016 Share Posted December 29, 2016 Why not ? Some of them looks like concretions or accretions. kidney stones Interesting would be seeing it in cross section.
