About age of the Bulawayan stromatolite Bul-7 (= P.P.R.G. 253 Scopf’s
collection number).

I found a reference which gave the recent Lithological map of the Bubi
greenstone belt and
also formations from in the Bubi greenstone belt of Zimbabwe (near
Huntsman quarries):

Explanations of the Lithological map (Figure 2.3, and pages 13-15 of

H: Gabro
G: Massive granitoids
S: Serpentinite and talc schist
yi: Banded iron formation
yl: Crystalline limestone

Shamvaian Group (x and xc):

x: Ndustshana Formation (greywacke and arkose)
xc: Ndutshana Formation (conglomerate)

Krogman's identification was based primarily on comparative human
anatomy but the specimen also was subjected to state-of-the-art
scientific testing -- the presence of Haversian canals and dried
