Because most of the time when people ask “if its an egg” it’s almost 99% not an egg. It’s actually happened so much there’s a sub because of how frequently it happens.
I am an absolute amateur with no credentials or formal education in paleontology. Having said that, I don't think this is a dino egg. Fossilized dinosaur eggs have 2-3 visually distinct layers in the shell, and the shell material is visually distinct from the interior medium surrounding the fossilized embryo in every picture of one I've ever seen. Fossilized dinosaur embryos are also extremely rare and only known from a few fossil sites around the world, most of which are in China although some specimens of Maiasaura have been found in Montana. Finally, the "embryo" in your specimen doesn't have anything that I can identify as part of a vertebrate embryo's anatomy.
It's certainly possible you have some other kind of fossil here, I'm definitely not knowledgeable enough to be comfortable definitively saying that's e.g. a concretion and not a fossil. If you're willing to provide a more detailed description of where you found it other than "in a river bed", I could maybe take a stab at it, but again I would strongly suggest asking over on r/fossils or something where you'll probably find an actual expert.
Your analysis is actually spot on. It’s not an egg for the reasons you gave. It is a concretion with a little something in it, which makes it interesting, but it’s not an egg.
Absolutely not an egg. It’s a concretion, a common structure in sedimentary rocks. Sometimes they contain a fossil which can be anything from a sliver of carbonized wood, a shell or more interesting things. The shell or fragment acts like a seed crystal causing a chemical reaction with minerals in the sediment such as iron. The reaction causes an accretion of harder minerals around the seed to create a spherical stone within the sandstone or shale.
Not an egg sadly but a concretion, but it IS really cool that you also see the nucleus of it. Concretions are formed when an object(nucleus)like a fossil, shell, or organics, are covered with precipitate of a long periods of time.
Looks like a fossil alright but not a dinosaur egg that is for sure. It looks like something more ancient to be honest. A type of aquatic fossil. Also you found this near a Riverbend which opens up the possibility of something aquatic. The rock looks right too. I would get this checked with an aquatic paleontologist, possibly cambrian or a similar era. Priapulid worm I found it. The shape is about right too. I looked up cambrian aquatic fossil and it came up very quickly. It might be something else but the resemblance is fairly close. A type of aquatic worm from the cambrian period. You still might have a fossil there so please keep it. You probably need am expert for this to he sure but that is my best guess from what I found so far. I am not an expert but I have seen this kind of fossil before several times.
No.
No..
Niet
It’s never an egg.
Once it was everyone was amazed and excited
Proof or it didn’t happen.
egg 1 egg 2 I couldn’t find them on this sub regretfully… so maybe they don’t count… sorry…
to be fair, the venn diagram of people who frequent all 3 subs is almost a circle
True thank you for being lenient on me.

Why does that subreddit exist D:
r/ThereIsAlwaysASub
i was gonna ask why this one exists too but there is always a sub ig!!!!

looks like a concretion to me
I don’t think the inside of a fossilized egg would look like that.

Haha awesome, I'm glad to get a concurring opinion! I agree that it's still a cool find but yeah, definitely not an egg.
No. Might be a concretion, might just be a rounded rock.
If it were an egg, you'd have no doubt. That's not an egg.

Not a Dino egg, but still cool!
You’re better off asking r/fossils

Here is an image of what I am talking about for reference. Look at the similarities.
No
Congratulations on your first concretion! You are famous and rich now!
It’s a rock
Thats the most rockest rock I've ever seen.
It definitely looks like a concretion with its point of origin visible
It's a very cool rock. Not an egg. Probably a pine cone or something
No unfortunately that is simply a rock
Probably. Maybe. Hell, I don't know. Maybe not.
Love the comments thanks everyone. I didn't break it It was 2 halves next to each other by the way. 😂

You broke it before figuring that out?
No it was in 2 halves
Incredible. I believe yes it is!
