Eggshell? Or bone...sorry guys.. it’s another egg question..

[Randyw]

Hi all! First of all I can’t believe I’m posting an is it an egg question LOL! But I was going through some Texas Permian matrix I just received and danged if this doesn’t seem like a piece of egg shell...  but there’s no way I’d be lucky enough to find a piece of Permian egg so I’m betting it’s bone but still.... sorry for another egg topic but I gotta know! Thanks guys and gals!

Looks more like turtle or a scute to me, but wait for the experts.

I am guessing it's part of someone's skull.

I think most of the animals you would find in Permian matrix layed eggs that were too soft to fossilize. 

And even the amniotes with hard shells were small at the time and it would be very thin.

Have any fossil eggs from the Permian been found?

Oh yes. Several and superficially they resemble this...but I haven’t been able to find a closeup..

I thought about that and that would be even cooler but all the pictures I can find of Texas Permian skulls are convoluted or bumpy  not porous and this is porous.

Interesting thought but it’s too early to be turtle shell or scute I believe ...

Any ideas @Troodon?

Sorry no idea, not eggshell

Cool! Means it’s a lot more likely to be a skull piece! YAY! Now from what is the question?

thank you @Misha @Troodon @Rockwood!

Isn't that type of bone by it's very nature porous ?

[Randyw]

Yes but this seems like the surface is almost all pore. For instance an eryops skull is mainly smooth and convoluted on the surface this is smooth and porous. And the surface seemed too porous for a skull piece if you know what I mean. But that would explain the angular fracture (suture) edges and the curve. Now I just wish I knew what it’s from! LOL!
