Dinosaur eggs said found in Russia's Chechnya

Dinosaur eggs said found in Russia's Chechnya

John Siebel wrote,
"The general opinion on the Paleolist is that they're concretions."

These alleged "dinosaur eggs" are clearly cannonball concretions.
Proof of this interpretation is seen in one picture that shows three
of these pseudoeggs merged together. For comparison, a collection
of pictures of cannonball concretions can be seen in (1.) "Tout ce
que la nature ne peut pas faire, IV : sphères de pierre" at:,45.html

(2.) " Boules de pierre en Slovaquie, République Tchèque et Pologne" at:

and (3.) "The Moeraki Boulders" at:

Some papers, which discuss in detail examples of such
natural stone balls, which are spheroidal (cannonball)
concretions are:
