The Brallier Formation was described by Charles Butts in 1918 as a fine-grained, siliceous shale with few fine-grained sandstone layers, from outcrops in central Pennsylvania.

The contact with the underlying Harrell Formation is generally gradational.

Hasson and Dennison reported the following fossils from outcrops of the lower Brallier at Keyser, West Virginia, Ridgeville, West Virginia, and McCoole, Maryland:[5] Type locality is at a railway station 6 miles northeast of Everett, Bedford County, Pennsylvania.

[6] Relative age dating places the Brallier in the late Devonian.
