Fossilized Nut?


MDHunter

Recommended Posts

I found this specimen at a location in Piscataway, MD. In the area I discovered it, I also found an abundance of turritella molds and fossilized sand tiger shark teeth.

But what in the world is this? It has the wedge like shape of a nutshell, but is completely mineralized (it's rock solid), and has an exterior texture that is possibly nut-like but could also be a skin-like texture.

Please help!

There are some locations not too far off Piscataway Creek that produce some interesting non-fossil concretions. Several of the specimens I found had bright red hematite centers that eventually turned brown when exposed to air. I have never heard of nuts being found in that area but nuts are fairly common in some strata around Pope's Creek.

I thought about that, but something about the exterior print/texture makes me question its viability to be a concretion.

That is a striking texture. It is consistent with that of iron-based minerals like hematite.
