base notes	Also speleld Dalaan. Wang et al. (2019) show as Zhang-Zhou (2007; Carb. Congress) -- begins with Profusulinella priscoidea fusulinid zone, which is the second zone above P. antiqua (Pf4) -- therefore, assumed it matches Profus. primitiva (Pf6) at base. Davydov'12 puts coeval with base of Russian Cheremshan. Geowhen had as slightly higher -- 80% above base in Bashkirian ICS Stage; and Menning et al show as MUCH HIGHER (lowermost Moscovian).				comp notes
