Fascinating coprolite or egg?

[Dino Dad 81]

It's hard to capture the beauty of this thing in pictures. Could it be an egg? Just a fascinating coprolite that shows its contents?

The more orangy/reddish (?) lighter portion around the exterior (shell?) sticks to the tongue very much, as do the more earthy/brownish-colored portions within--especially the small oval right in the center that has the same orangy/reddish color as the exterior (yolk?).

This looks like a somewhat weathered ironstone concretion to me.

I see lots of these ironstone deposits

Ironstone concretion, very similar in appearance to Mazon Creek nodules. It may contain a fossil as many concretions form about an organic nucleus.

Dont lick rocks.  Its a horrible way to "test" for fossil/non-fossil and there are lots of things in and on rocks that arent healthy to ingest.

So that explains the psychedelic experiences I've been having while searching for fossils...I thought it was just too much staring at rock and dirt...

Thanks for the heads up.
