Egg shell?

[Philo78]

I found this rock in the desert outside St. George, Utah. It looks like an eggshell to me, but I have no experience here. I'd appreciate any thoughts!

Welcome to the Forum.  

Unfortunately, I think this is a Concretion, rather than an egg. 

The "rind" on this doesn't look like eggshell to me. Too thick, and not the correct texture.

Wait for some more opinions, though.

I agree. Not an egg.....

I think it is a weathered chert nodule

Welcome to TFF!

I agree with a chert nodule that has a wethered "skin" on it, not an egg.

Welcome to The Fossil Forum!

 

Agree with the others, just a simple concretion. Sorry!

Utah has many great fossils though, so you should find some pretty soon if you keep looking!  

If I were you I would check out U-Dig. I've never been there, but I've heard it's a really fantastic place to hunt for 550 million-year-old trilobites (and brachiopods and sponges)!

 

Happy hunting!

PS: when I saw "egg shell" as the title, I was already getting excited at seeing some nice Laevicardium fossils... Oh well

Thanks to everyone for the input. I'll have to decide how (or if?!) I break the bad news to my kids.

I wouldn't just chuck it I would hang onto it. It seems interesting to me it looks like it has more than one layer. Perhaps some sediment covering the outside??...and that inner gooyness looks like the inside could have been a liquid....of course this is an opinion from another newbie.

When cryptocrystalline quartz is exposed to the elements (weather) it begins to hydrate (pick up water).

The "layers" of this rocks exterior show the hydration that has occured to this rock.

still learning, as a lover of weird things I think this rock is very interesting...I do a lot of art so i tend to see things in rocks most dont...makes it hard to find real fossils when my eyes see what they see...lol....I have a whole box of look likes and its growing. Some times I find them more interesting than the real fossils. They are natures way of saying...."gotcha! fooled ya again".

You are not alone, check out this thread....

I've never seen the cortex weather differently from the interior chert. Usually the chert and the cortex( outer rind) blend into each other gradually, going from grainy outside to hard in the center. I'm a bit thrown off by this weathering. The outside looks bony, though probably not.
