Tarrant County help identifying

[JNL85]

I found this back where an old railroad used to run around World War II, I've seen other artifacts online with similar markings but now I've googled my life away and can't find anything! Any help is appreciated, Thanks

They look natural to me ... I'm sure some others will chime in that can offer some opinions

Ahh there's gotta be some experts on here somewhere. :-(

It's the same as this, Correct me if I'm wrong but isn't it flint?

Welcome to TNET!

It appears to be a normal looking rock.
