Meteorite or grapeshot? Imbedded in rock. What is it?

What's bad about them? No fossils?

No, it's only because of its aspect. It's sometimes used for construction.

All look like iron concretions. They are very seldom magnetic.

They do not look like coprolite to Me, but @GeschWhat or @Carl may feel different about that.

Sorry, I see nothing convincingly coprolitic.

I concur with Carl.

I promised grapeshot.  I still have not found the one I was talking about, but I found a nice broken one and two smaller specimens.

All found near San Antonio, and not garluche.

I hope I will find the other one!

That really looks like a concretion to me. I have many that are perfectly round.

I agree with Lori, they look like concretions.

Grape shot was made from lead balls, not iron.

Iron is to hard and would damage the cannon bore, eventually causing a catastrophic failure on the cannon.

I also agree with Lori and Tony, concretions may be perfectly round.

Okay, you folks know more about this stuff than I, so dang, could be!  The smaller ones I was never too sure about.  And I never had anyone check out this larger one.

But it is very similar to the one I still haven't located...

As I said, that one I took to the UTSA Center for Archaeological Research, and had one if their curators give me their opinion.  I spoke with Anne Fox and she identified it as grapeshot.  She seemed genuinely interested in the artifact and informed me that the site where I found it, Shavano Creek, was a location where the early Texans had skirmishes with the Mexican Army.

That piece of 'grapeshot', if it is grapeshot, is a bit larger but similar to the one in the picture.  Looking at this one, though, I feel there are some differences that you folks may find obvious.  I hope that I can find the one I was told was grapeshot so I can gather your opinions!

just another shot for the grapeshots
