Is this a real fossilized dinosaur egg?

[iglyphics]

I just bought this dinosaur egg fossil and would like opinions on its authenticity. It is spheroid, 3 inches in diameter, porous and pitted texture. Cracks present as one would expect in a fractured shell. 

Thanks for any insights.

Did you read 

This looks like a concretion to me, possibly sandstone. 

It seems layered, doesn't have eggshell texture and if that were a shell, it's too thick for the baby to break out.

I’m seeing a concretion also.

Concretions can contain fossils, might not be a bad idea to break it open and see what's inside.

 I'm always late for the party, but yeah, this is not an egg, it's a concretion.  Like JBKansas has said, there might be a fossil inside?  Good luck
