A friend found this along the Little Missouri River Just outside Mena Arkansas. I believe the area is early Cretaceous. My first thought was a Septarian Nodule. Is it that or something totally different?

Limestone with a band of quartz running through it, I think. 

Try a vinegar test and see if the rock or the band running through it fizzes.

Quartz vein for sure, but I think it is in a quartzite sandstone type rock.

Concur.  Quartz cobble with quartz-infilled vein.
