Looks like another potato to me.


Actually WMR, what you have there is a fossil. That is coral. Actually, several different types of coral from what I can tell from your picture. Very very very very common.

 

Also, the term 'mineral egg' is synonymous with geode.

 

Yea that's what I'm finding.

 

My girls told me to tell you thank you.
They are excited, even thou it's not a fossil.

 

Thanks RP. It's cool to know what I have anyhow, at least I can appear intelligent when someone says "Hey, what have you got there?" I don't have to tell them it's an Alien egg or a dinosaur brain or dino poo (yuck, thanks for that thought Tritoneer!) I can answer "Why, anybody can see that it's several different types of fossilized coral". Now don't I sound smarter already!!
