Breviscutellum sp.

     "This Oklahoma specimen assigned to Breuiscutellum is closely similar to Decoroscutellum indefensum Maksimova, 1968, a species which on pygidial, and probably cranidial, morphology seems to be more closely allied to Breuiscutellum than to Decoroscutellum. D. indefensum is recorded from the Tiversk and Pribalkash (Ludlovian to Lochkovian) stages of Kazakhstan. The main difference between the Oklahoma and Kazakhstan species is in the structure of the posterior part of the median rib." See referance below.
