Mammal Embryo or Dinosaur egg or Rock?

[magigcnn]

I already asked about this rock in some fossil forum but yet it remains unidentified. I have my own guesses but in reality I don't have a clue about fossilized things. I found it in Germany Bavaria, the stone is shelly limestone and the egg like mold is about 1 cm in length and wide. I would be glad if someone of you can identify it :)

A calcitic, or possibly siliceous , agglomeration within a sedimentary rock, I would say. 

No sign of egg-form or eggshell texture and embryos just don't preserve in that way. 

Geologic, I'm afraid.

Definitely NOT an egg or embryo. No egg shell texture. No real bones visible. 
Soft tissue does not preserve in this manner.

 

This is the only fossil I see.

Very nice brachiopod! I agree with others, though, that the "embryo" is geologic in nature. Happy hunting!

If I'm looking your second picture I think I can see a crinoid columnal in transverse position (five fold symmetry plus the cetral portion wich may be the lumen). If the geological time would be Jurassic, you could have there a brachiopod-crinoid duality.

I suspect these radial hints are septa in a rugose horn coral which had an especially robust theca. The large scale morphology is far more informative, but details are seldom preserved since it it was thought to be an adaptation to turbulent conditions.
