Rock with layers?

[Charmin]

Does anyone know what kind of rock this is? It has layers--is this called "sedimentary"? It feels gritty and can be scratched easily. I found it on a gravel bar while artifact hunting. It was the only one like it on the whole gravel bar. All the other rocks on the gravel bar are sandstone, limestone and chert---Does sandstone form in layers like this sometimes? Found in Northeastern Oklahoma. Thanks for looking and any help!!!

Looks like sandstone. Based on your location, very possible.

Deposited in layers over the years, sometimes in shallow lakes which become progressively more shallow.

Siltstone is similar, but has a finer grain, i.e. "silt". In British Columbia, Canada, siltstone preserved some of the finest fossils in the world, including some of the earliest known truffle-like fungi with club moss roots.

Thanks Cappy Z.... . Sorry if this was a silly question---it was just such an unusual rock and kinda neat so I brought it home for my rock garden.

Thanks so much, Tuberale! I thought maybe it was sandstone--it was found in a dry creek bed/gravel bar. I had never seen sandstone quite like this before, so it made me curious as to what it was, and I thought I would ask.
