Is this really a dinosaur egg? from Michigan

[Squidpastry]

Hello! I'm new to the forum- this is my first post. Apologies if I make any mistakes here!

My mother has had this dinosaur egg(?) in her possession ever since she was a child- it was gifted to her by her father after he had found it at the side of the road while driving. I'm not sure where specifically it's from or even if it's biological in nature at all.

....Now, I've wanted to finally conclude if this is truly a dinosaur egg (or egg of any other organism) or an interesting geologic formation. Dinosaur or not, it's a beloved object and I'd like to find out it's true identity! 

The whole thing is approximately 7cm long, 5.5-6cm wide, and the yolk(?) is approximately 4cm in diameter.

Not an egg, unfortunately.

This looks like a flint or chert nodule.

 

See these topics for further exploration.
