Help Id-Ing Egg Or Rock?

Hello Everyone,

This is my first post so forgive any errors I may make that may not follow standard post guidelines (which I did read).

Anyways, I found this "thing" while performing a prescribed prairie fire in south central MN. It was out in the middle of a field tucked under some grass. Luckily I picked it up before the fire came through. It is heavy in your hand (like a rock) 11.8 oz. It is 8-1/8" diameter and approx 3-3/4" length. It has obvious layering over the entire face (like an egg). If it's an egg.. it's too big to be a goose egg, in my opinion. Not the right shape for a sandhill crane. I've thought of all sorts of birds and can't think of which it could be. Too big to be a turtle egg from around here too. Perhaps it's just a rock, perhaps it's an egg, perhaps it's something i'm not thinking of... I'm just fishing for any input for curiosities sake.

Thank you for your help in advance. I appreciate it.

This is one of the better egg-mimics to come along; all it lacks is an eggshell texture.

It is either a water-worn cobble, or possibly a concretion.

Agreed. It's close.

Suspicious that it was tucked under some grass. I wonder if there were other rocks in the field. If so, were they angular or rounded?

The prairie soils contain a lot of rocks; freezing and thawing work them inexorably to the surface.

Welcome to the Forum!

Not an egg,concretion I presume.

Thanks everyone for your input! Lacking the cracked egg texture is why I didn't have my hopes up. I'm glad I have some ideas now though. I may still pretend that it's an egg, lol. Perhaps some day I will come across lapidary equipment able to cut it in half... to know the real truth....
