V. Rai et al., DISCOVERY OF CARBONACEOUS MEGAFOSSILS (CHUARIA-TAWUIA ASSEMBLAGE) FROM THE NEOPROTEROZOIC VINDHYAN SUCCESSION (REWA GROUP), ALLAHABAD-REWA AREA, INDIA, Current Science, 73(9), 1997, pp. 783-788
Well preserved carbonaceous compressoins and impressions of Proterozoi
c mega algal assemblage Chuaria circularis-Tawuia dalensis are recorde
d for the first time from the upper part of the Rewa Group, Vindhyan S
upergroup, exposed in an escarpment near the town of Allahabad on the
Madhya Pradesh-Uttar Pradesh border, These millimetric-sized fossils r
epresent an important event in the evolution of the Proterozoic biosph
ere. The significance of the present record indicates towards continua
nce of macro-organic community across the entire Vindhyan sequence, Th
is aspect has been discussed in the light of previous records from Ind
ia and abroad and its bearing on the age of the upper part of the Vind
hyan succession and correlation of the sequence on a regional scale.
