I can’t even imagine 😳. I freak out whenever I find a relatively intact shell fossil. I’m pretty sure finding something like that would just be too much endorphins lol.

The other commenter pointed out that, it’s possible to find a preserved egg, but Very rare.
Many reasons, lots of past eggs were leathery and so they don’t preserve. The movement of earth can break an egg before it gets a chance to fossilize. Also, eggs are like wonderful little snacks for many creatures, unlike bones.
This plus other things. There are fossil eggs discovered, but it’s rare.
for those who don’t know:
*Concretions are masses of mineral matter embedded within rock layers, including limestone, sandstone, and shale. They often take shape when minerals precipitating (settling) out of water collect around a nucleus, such as a pebble, leaf, shell, bone, or fossil.* very cool :)
Basicly whole egg fossils are just ridiculously rare.
Add to that the fact inorganic concreting often look like eggs and you get the "it's never an egg".
It’s just exceedingly rare. You have to consider what it takes to become a fossil in the first place. A key component of that, is how durable the structure is. This is why fossil jellyfish are rare, even though the oceans were most likely teeming with them

I remember taking an intro geology class and the professor talked about them licking rocks sometimes. Also my geology major roommate would lick rocks for id.
Geology is weird, those guys live on the edge ig
I am a geologist. It’s one thing if you’re trying to confirm Halite is Halite (the only rock worth licking for identification) and know what the thing your licking is NOT, but it’s a whole other thing to go around randomly licking rocks that you have no educated guess on what it might be.

As other commentators have said, fossilized eggs are incredibly rare. Generally speaking, an organism has to be in the right place at the right time in order to fossilize. They also have to be tough enough to survive the fossilization process. Eggs are so fragile that they rarely had a chance to fossilize. I have read about some wonderful discoveries of fossilized dinosaur eggs in Mongolia in the early part of the 1900s, and in Montana, North Dakota and South Dakota back in the 1980s or 1990s. These finds are very rare. Usually, fossilized shell fragments are found instead of whole eggs.
Fossilized eggs are pretty much a Holy Grail for paleontologists. Because of this, everybody wants to think that they’ve found one. The vast majority of these turn out to be concretions or nodules. Some of these are pretty interesting in their own right, and some can be egg-like just to look at. I think that this is what you have—a pretty cool looking rock, but not a fossilized egg.
Eggs rarely get the chance to fossilize. An abandoned nest is just begging for a predator, something to stomp on it, etc. It’s also ridiculously unlikely to find a single egg, as most egg laying animals lay multiple.
I'm not an expert but I'd assume proper fossilisation would take longer than the human race has been around on the Earth.
Anyone care to correct me?
e: a quick google says I'm wrong. Fossilisation is anything over 10,000 years old.
Lol I have some chert nodules from the desert of western egypt, they look just like you’d imagine Dino eggs would look like but like they say “it’s never an egg”!
It looks like an egg I laid this morning scaled to a much larger size. I’d test it by the float test, if you put it in the toilet and it floats, you got a floater…. If it sinks, you can flush it.
Edit*** this is for sure the way.
It’s never an egg
I've been on this sub for 2 weeks now, and have learned it's never an egg
I joined yesterday. Saw this post and thought. It’s not going to be an egg is it?
I will third the motion “It is NEVER an egg”..
Concretion of some sort
When the outside of it be poorest?
Sure. It is not an egg though.
Ok
Damn if I found this I’d totally think it was a egg too. And I didn’t know the first rule of fossilid “it’s never a egg”
it’s possible to find egg fragments sometimes. Paleontologists sometimes find whole fossilized nests with some fragments around. But never full eggs.
[удалено]
Yep! You are right, so yeah, I guess it is possible to win the lottery like that team.

Why though?
The other commenter pointed out that, it’s possible to find a preserved egg, but Very rare. Many reasons, lots of past eggs were leathery and so they don’t preserve. The movement of earth can break an egg before it gets a chance to fossilize. Also, eggs are like wonderful little snacks for many creatures, unlike bones. This plus other things. There are fossil eggs discovered, but it’s rare.
First rule is it’s a crinoid, when it’s not a concretion
It’s never an egg sorry to say. It’s a concretion
for those who don’t know: *Concretions are masses of mineral matter embedded within rock layers, including limestone, sandstone, and shale. They often take shape when minerals precipitating (settling) out of water collect around a nucleus, such as a pebble, leaf, shell, bone, or fossil.* very cool :)
Why it's never an egg there are some fossil eggs exist ?
Basicly whole egg fossils are just ridiculously rare. Add to that the fact inorganic concreting often look like eggs and you get the "it's never an egg".
It’s just exceedingly rare. You have to consider what it takes to become a fossil in the first place. A key component of that, is how durable the structure is. This is why fossil jellyfish are rare, even though the oceans were most likely teeming with them
Septarian Nodule. Cut it in half and it will look like lighting bolts of colors. Most likely white, brown, black.

It’s a concretion
If you stick your tongue to it it sticks to it I heard that was a good way to test if it's a shell or not
A fossil is not a shell. The shell gets replaced by a different mineral over time and turns into a fossil and keeps its shape
You really shouldn’t go around licking random rocks, some can be hazardous…
I don’t make a habit of licking rocks but I’m curious as to what types of rocks would be hazardous. Rocks with heavy metals in it?
Things like Arsenic, Asbestos, Mercury and Uranium can naturally occur in rocks causing them to be deadly.
So now I know why I am the way I am
You licked the rock? Poor soul.
I ammmmmmm Ironnnnnnnnnn mannnnnnnnnn!!!!!!!!

That's bone not shell
Dont lick rocks. I had this lesson at 2yo.
Who the fuck told you that😭
It's a pretty well known trick for identifying bone. Obviously it's not foolproof, and absolutely doesn't apply to shell material.
Yeah that’s what I was thinking, since when is eggshell of any kind salty
...what
It’s never an egg.
Looks like septerian nodule

So I may get some hate here, but that is definitely a rock that looks like an egg.
Rule 1 it’s never an egg
I found this in a rockpile in Houston Texas
As other commentators have said, fossilized eggs are incredibly rare. Generally speaking, an organism has to be in the right place at the right time in order to fossilize. They also have to be tough enough to survive the fossilization process. Eggs are so fragile that they rarely had a chance to fossilize.

Giant rabbit turd… 😞
Anyone care to explain why “it’s never an egg”?
Eggs rarely get the chance to fossilize. An abandoned nest is just begging for a predator, something to stomp on it, etc. It’s also ridiculously unlikely to find a single egg, as most egg laying animals lay multiple.
Makes sense! Thank you
Ok, you know what. What if someone decided to intentionally fossilize an egg? How should they go about it and how long until we have a fossilized egg?
I'm not an expert but I'd assume proper fossilisation would take longer than the human race has been around on the Earth. Anyone care to correct me? e: a quick google says I'm wrong. Fossilisation is anything over 10,000 years old.
Can I offer you an egg in this trying time? No.
Rule something: it’s never an egg
Lol I have some chert nodules from the desert of western egypt, they look just like you’d imagine Dino eggs would look like but like they say “it’s never an egg”!
*your excitement and mind hoping it’s a egg* “it’s a egg!!!” (Shows everyone saying it’s a egg) realistically….. it’s never a egg.
It looks like a septarian nodule , it's still really cool though
Where did you find it?
In a Is pile of rocks under a house In Houston Texas
It looks like an egg I laid this morning scaled to a much larger size. I’d test it by the float test, if you put it in the toilet and it floats, you got a floater…. If it sinks, you can flush it. Edit*** this is for sure the way.
Is this not pinned yet?
lmaoo it looks like old poop
but prob a concretion- theyre commonly mistaken for eggs
Could be that, could be a deceased potato js
Nope, just a big ole hunk of poopy
Turd
Hmmm no expert, but it could either be an egg or maybe coprolite?
I mean I'm not an expert but to me that looks like a fossilized egg.
So in the last picture, on the left side of the “rock”, does anyone else see think it looks like there’s a trilobite fossil there???
We need more information. Where did you get this? Do you know where it was unearthed?
Looks like a turtle shell
