Poropudas, Vesaisentie 9E, 90900 Kiiminki, Finland, Date: 12.12.2008) Three rough data set (TABLE 1, days/month, TABLE 2, days/year and TABLE 3, months/year) are given in this paper for test purposes of ancient fossil time data. Numbers are based on Giorgio Pannella’s (1972) fossil time data. Interpretations are my own. These linear extrapolations are based also on uncertain assumption of existence of oscillation about 429.4 Ma in Pannella’s Figure 3 (days/month). Many ages and fossil points are still uncertain. Main intended area of use of these figures is about 0-2000 Ma.

It should be remembered that these linear extrapolations are based on my uncertain assumption of existence of oscillation of period 429.4 Ma in Pannella's figure 3 (reference 2) and ages and data of fossils and stromatolites are in many cases uncertain too. The Elatina Formation and Reynella Siltstone ----------------------------------------------------------------- 620 Ma: ----------- 655.6 Ma, 410.28 days/year (Drawn extrapolated figures give roughly approx. 412 days/year) 639 Ma, 31.49 days/year (Drawn extrapolated figures give roughly approx. 31.7 days/month) 410.28/31.49 = 13.03 months/year, (primary value = 13.1 +-0.1 months/ year) 649.4 Ma, 13.16 months/year (OUM-DT2 based) (primary value = 13.1 +-0.1 months/year) (Drawn extrapolated figures give 412/31.7 = 13.0 months/year) (13.0-13.2 months/year) The Big Cottonwood Formation -------------------------------------------- 900 Ma: ----------- 890.2 Ma, 33.34 days/month 897 Ma, 33.06 days/month 904.2 Ma, 33.48 days/month (33-33.5 days/month, average = 33.29 days/month) (Drawn extrapolated figure gives roughly approx. 33.4 days/month) 874.4 Ma, 463.33 days/year 911 Ma, 449.61 days/year 911 Ma, 453.42 days/year (450-463 days/year, average = 455.45 days/year) (Drawn extrapolated figure gives roughly approx. 451 days/year) 455.45/33.29 = 13.68 months/year, (primary value 13.5 months/year) (Drawn extrapolated figures give 451/33.4 = 13.5 months/year) 928.8 Ma, 13.71 months/year (OUM-DT2 based) 928.8 Ma, 13.82 months/year (OUM-DT2 based) (13.7-13.8 months/year, primary value 13.5 months/year) (13.5-13.8 months/year) The Weeli Wolli Formation -------------------------------------- 2450 Ma: ------------- 2438.9 Ma, 39.21 days/month (Drawn extrapolated figure gives roughly approx. 39.2 days/month) 2423.9 Ma, 587.87 days/year 2423.9 Ma, 578.11 days/year (578-588 days/year, average = 582.99 days/year) (Drawn extrapolated figure gives roughly approx. 585 days/year) 582.99/39.21 = 14.87 months/year, (primary value = 14.5 +-0.5 months/ year) (Drawn extrapolated figures give 585/39.2 = 14.9 months/year) 2437 Ma, 15.76 months/year (OUM-DT2 based) (primary value = 14.5 +-0.5 months/year) (14.9-15.8 months/year) Reference (1). The Gunflint Formation ------------------ 1878.3 +-1.3 Ma: ------------------------ 1927.2 Ma, 36.97 days/month (Drawn extrapolated figure gives roughly approx. 37.2 days/month) 1846.3 Ma, 549.75 days/year (Drawn extrapolated figure gives roughly approx. 533 days/year) 549.75/36.97 = 14.87 months/year (primary value = 14 months/year) (Drawn extrapolated figures give 533/37.2 = 14.3 months/year) 1937.6 Ma, 14.99 monnths/year (OUM-DT2 based) (14.3-15.0 months/year) Age of the Bulawayan stromatolite UCLA-Bul-7 ? ---------------------------------------------------------------------- Mode = 10-20-40, Highest Count = 41. 2576.6.4 Ma, 40.11 days/month 2595 Ma, 40.35 days/month 2607.8 Ma, 40.64 days/month 2614.6 Ma, 40.34 days/month 2621.8 Ma, 40.78 days/month 2634.5 Ma, 41 days/month 2650.8 Ma, 40.9 days/month 2786 Ma, 40.62 days/month 2868.3 Ma, 41.04 days/month So age of the Bulawayan Stromatolite UCLA-Bul-7 could be: 2580 Ma - 2870 Ma. (primary value of the age = (2672 +- 12 Ma - 2715 +- 15 Ma), Upper Bulawayan Group or (2831 +- 6 Ma - 2904 +- 9 Ma), Lower Bulawayan Group. These both are not local age determinations from the Bubi Greenstone Belt near Huntsman Quarries, Zimbabwe.)
