Not a clue on what this is

[dcinffxva]

posting this for a friend. She found this item near a riverbank. It was eyeballed, not detected, and although it looks it, does not indicate as metal on a detector. It does not respond to a magnet either. Anyone have a clue ?

Is it rock,if not,maybe a seed pod?

It is similar, but it is thicker, and Brazil nuts aren't commonplace in Virginia.

Limonite concretion. Somtimes forms around a small fossil or just a lump of mud. I'll bet there are some other pieces like it, but of different shapes, in the area where it was found. Limonite, although a iron ore of sorts, isn't magnetic or shows up on a detector. Thank God. An area where we go arrowhead hunting, and have detected several bullets while looking for meteorites, is choc full of limonite. The most common is a flat piece looking like a 3/8th in. thick piece of iron, or small balls of various sizes, many looking like rabbit turds. I found one piece that looked like a good chunk of Borman shell. Round curvature, nice hollow inside, etc.

PS: I have one piece, bit larger than a golf ball, that looks like an acorn. And it has surface features like yours. Maybe we should both donate our pieces to the "Limonite Nut Museum". I think I will donate mine by mail.....

Have to admit, never heard of a limonite concretion before. You could be totally making it it up, but it is a great explanation ! I did search it and looks plausible. Thanks !

I only make things up when I am writing about the annual spaghetti harvest in Italy. Sometimes. Usually the truth is strange enough. But next time I go arrowhead hunting, I will be sure to pick up a number of pieces of limonite so I can include photos. I promise a nice little pile of "rabbit droppings".

Limonite concretion for sure . We have it all over the place here.

I always thought the harvesting of spagetti from trees was a true fact!!

Of course it is a true fact. I saw it in a newsreel type movie. This year is up for a record picking. They are importing buxom maidens from outside areas for extra laborers. It will be a boon to the sagging Italian economy.

It almost looks like sand fulgurite- Fulgurite is created when lightning stikes the sand and leaves a fossilized glass capsule or tube. In fact the term fulgurite comes from the latin term fulgrum or thunderbolt.
If the item you have is steel, it almost looks like the tip of a sword scabbard.
