egg or strange rock

[dcwhizbang]

i prefer to play in the dirt to find fossils but i couldn't pass this up at an estate sale.  price was right so i brought it home to study.  not sure where it came from.  any info would be much appreciated.  thanks

Neat looking piece. Perhaps a septarian concretion?

the sale joked that it was a dinosaur bone.  it was just too interesting to pass up

Well there's your clue right there.  If it were an actual dino egg, they wouldn't be joking around with the ID. 

 

I'm pitching my tent in the Septerian nodule camp also.

Not an egg.

Very cool rock though.  

Just think about it: even if it had been a dinosaur egg, it's not as if you could have enjoyed it sunny side up. :-)

Nice looking ironstone and limonite septarian concretion, I think.

i do appreciate the responses.   It will be labeled "septarian concretion" and displayed along with my other rocks and fossils.  thanks again.

I like my eggs in many different ways depending on my mood, but in this case I like them just the way they are. What a very interesting concretion! I would have jumped on it immediately.
