Paul and List, does this help??

Looking at the lowermost figure in the Chinese article, I have to
wonder, being unable to read Chinese, if the author of the Chinese
article is confusing them with the man made stone balls in Costa
Rica. (A translation of this article would be greatly appreciated.

According to geological experts in photo analysis, the "stone eggs" is a
rare stone in the large carbonate nodules. fluctuations in the water for a
nuclear center, a rolling snowball has gradually taken shape.
???????????,??????????,???????????????As to what the exact ingredients that
can be analyzed to determine, for a lot of uses of stone eggs are also
pending verification.
??????,??????????????,?????????"????",????????????????????

kevin decker asked if the "Mysterious stone eggs..." from Hunan
Province..China. were "Something like The Eggs from the Osceola
Impact Crater?"

No. They are meter-scale, cannonball concretions. Cannonball
concretions, composed of carbonate-cemented sediments, of their
size have been found in a number of places, including:

1. Rock City, Kansas

http://en.wikipedia.org/wiki/Rock_City%2C_Kansas

2. Along the along the Cannonball River within Morton and
Sioux Counties, North Dakota

http://meteorites.wustl.edu/id/cannonball.htm

3. In the Frontier Formation in northeast Utah and central
Wyoming.

4. Along the shores of Hokianga Harbour of Hokianga, North
Island, New Zealand

5. near Mecevici, Ozimici, and Zavidovici in Bosnia-Herzegovina

and 6. near Moeraki, South Island, New Zealand

Some papers, which describe, illustrate, and discuss the origin
of cannonball concretions, which are similar in size to the
Chinese "mysterious stone eggs" are:

The original article which discusses the "Mysterious stone
eggs" is:

Mysterious Huge Stone Eggs Discovered in Hunan Province, Epoch
Times Staff, April 17, 2007.

It can be found at:

http://en.epochtimes.com/news/7-4-17/54224.html

The article stated in part:

 "Upon photo analysis geologists believe that the
 stone eggs are rare, large concretions of the
 carbonate rock. They were formed, starting from a
 tiny nucleus in the center, snowballing slowly in
 the oscillating sea water."

In this sentence, the reporter has very likely either mistranslated
what the geologists told him or her or is indulging in some poetic
license in writing his his story. No geologist, whom I know, would
argue that these concretions formed like snowballs. Instead, these
concretions, like many other cannonball concretions, started growing
within sediment underlying the bottom of a sea or ocean only after
it had accumulated. In the pictures accompanying the articles,
the original layering of the strata, in which the concretion grew,
can be seen as concentric rings around one of these concretions.

Looking at the lowermost figure in the Chinese article, I have to
wonder, being unable to read Chinese, if the author of the Chinese
article is confusing them with the man made stone balls in Costa
Rica. (A translation of this article would be greatly appreciated.
