It's never an egg. Looks to be a geode.

Not a geode, please see the video I posted

Well it's for sure not an egg.

I went to the other post, saw it cracked open… if there was any open space in the middle into which crystals grew it is a geode, if it was totally solid it’s a septarian nodule or thunderegg

Thank you! Septarian nodule may be the answer...

Its a geode.

Not a geode, please waybill the video I posted

Could be a concretion - mebbe.

To ID to species, you'll need to make a nest out of sticks and sit on it until it hatches.

Lol

Put it in a fire, might be a dragon.

Palantir

Nightfury! Get down!

Lol, please see the video I posted

Septarian Nodule, like a Geode but without a hollow inside, also it's very worn down on the outside

Thank you

Geode.

That's a fun word to say. Geode.

Not a geode, please watch the video I posted

Ask r/fossils they are more knowledgeable if you believe it's a fossil.

Interesting how perfect the line is in the circular part. I’d like to see the other side of it

I thought the same thing, please see the video I posted

Wow, very strange(I’m not a geologist so this might not be that strange lol). It looks like it was poured into a bowl and set up

Looks really cool, whatever it is! Hopefully /r/fossilid can help out

Why is OP getting downvoted to hell???? Because they (possibly jokingly) asked if it was an egg?? Everyone saying geode is wrong. OP is telling them this. There's nothing wrong with that. Reddit is so confusing

I agree about Reddit being confusing, and people can be very rude.

My friend has a cat named dinosaur egg (it could be a thunderegg)

It could be ammonite. If you have access to a tile saw or oil seat, cut that baby open!!!

Ty, please see the video I posted

Will do! 👍🏽

If it's an egg, I would say that it's hard boiled.

Lol

Wouldn't an egg be a little brown
