Fossilized Egg

[therocksharks]

I found this one and a few more by San Carlos Lake, it is an egg right?

Not an egg.... have a search on this forum, there is a really good guide you should check out to understand why it's not  
One big giveaway is the texture! 

[Troodon]

Agree just a suggestive rock.  There is also no eggshell present.

[RJB]

Roundus rockis.  Most likely a concretion

As stated above the somewhat rounded shape is about all that this rock shares with a fossilized egg--lots of rocks are rounded and a fossilized egg requires many more features. This post by our resident fossilized egg specialist might prove informative:

Thanks all! I'm still a little wet behind the ears!?

What about this one?

 

[therocksharks]

I'm finding these myself, so I know they're real (rocks at least)! Lol

[therocksharks]

If I'm not taking too much of your time I'll add some new ones I just got, almost gave me a heart attack in 114 AZ degrees!

The Rock Sharks again...

I was told it is shark poop?

Wet behind the ears might possibly keep you cool in the roasting summer heat.

Yikes! Hope you are bringing lots of water for hydration while you are out rock-houding.

 

Neither of these two new ones show any signs of being fossilized eggs (which are really very rare).

 

Please review the post on how to recognize fossilized eggs and tell them from the rocks that often confuse folks into believing their finds to be eggs:

We have a resident paleo poop-ologist who really knows her...um, well, let's say 'poop'.

 

@GeschWhat

 

I'm not seeing any overall morphology (shape and texture) that would indicate any type of coprolite here. It appears to be some interesting mineral crystals and not seeing anything more suggestive than that.

Thanks all for your analysis', I really appreciate it (even though I feel kind of moronic!)!

[Lone Hunter]

Don't feel moronic, quite the opposite, your smart for asking and that's the only way to learn. Safe to say hundreds of people have posted what they thought were eggs or poop so your not alone.

Questions are the gateway to knowledge. Don't feel bad--feel educated.

 

As mentioned above we see a steady stream of "fossil eggs" (usually "T-rex" and quite often with suggestive "embryos" within). The problem arises when people new to fossils stick to their guns and refuse to suggest the accumulated experience of those on the forum who have seen their share of both not-eggs and eggs. Acceptance that their first "faker" rocks are simply misleading geologic tricks my Mother Nature often stops folks from progressing on to finding actual fossils in their area. Arizona is one of the states where fossils may be found. If you are truly interested in hunting for fossils I'd suggest looking into local(ish) fossil clubs. A quick internet search turned up this link which may be of use:

Additionally, have a look through the postings in this section of the forum for ideas on where to hunt:
