V. Rai et R. Gautam, DISCOVERY OF SILICIFIED MICROFOSSILS FROM THE KHATPUL FORMATION, SHALI GROUP (NEOPROTEROZOIC), H.P., INDIA, Current Science, 74(6), 1998, pp. 541-545
Well-developed organic walled microfossils of cyanobacterial affinity
are recorded for the first time from the bedded and stromatolitic cher
t units of the Shall Group (Neoproterozoic). The present discovery enh
ances our knowledge of the palaeobiology of the Shall Belt which has s
o far yielded only stromatolites. The association of these silicified
microfossils with columnar stromatolites signifies the close ecologica
l relationship between the two. A correlation of the Shall Belt with a
djacent belts of the Lesser Himalaya has been discussed in the light o
f the present discovery.
