Abstract

A resin-embedded male Culex mosquito, beetle larvae and dwelling spaces viz., galleries and chambers of Ambrosia beetle were recovered from the shallow shoreline Tertiary sediments of Warkalli Formation exposed along Kerala coast. Lumps and rods of resin are found associated with the impure lignitic clay beds of the sequence. It indicates that the vegetation growing during that time was dominated by resin producing plants and the conditions were favourable for the insects to get entrapped in the gum. Such organic remains are useful in the study of fossil DNA

Abstract

The organic matter dispersed in the upper Tertiary sediments of Mahuadanr valley has been studied in detail. It has been observed that the amorphous, structured terrestrial and biodegraded terrestrial organic matter represent the dominant types followed by black debris and fungal fruiting bodies. The dominance of amorphous organic matter suggests the prevalence of reducing conditions in the basin, patticularly during the deposition of the lower part of the sequence. The conditions gradually transformed into oxidising environment during the deposition of upper part of the succession. Besides this, the presence of black debris indicates moderate oxidising environment in the source area and also during the transport of the organic matter.

Abstract

Silicified cyanobacterial remains are recorded from the black cherts interbedded in the Donimalai Formation of the Archaean Sandur Schist Belt and amorphous organic matter in the stromatolites underlying Deogiri Formation of the same belt. The presence of elemental carbon at the fringes of the cyanobacteria is confirmed by microprobe analysis. Carbon (δ¹³C= -1.4 ± 0.5% vs PDB) and oxygen (δ¹⁸O= + 10.6±0.5% vs SMOW) isotopic ratios and the presence of cyanobacteria extend the existence of photosynthetic activity into the Archaean.

Abstract

A microbialite morphospecies Stratifera undata has been recorded in the Blaini Formation of Mussoorie Syncline and is systematically described. It is inferred that this mat complex was deposited in an upper intertidal region in subtropical climate. The age of this microbialite morphospecies is suggested to be Upper Riphean/Lower Vendian.

Abstract

First record of Type I matured, Liptinite organic matter facies from the Gotan Limestone (Late Neoproterozoic) in Rajasthan is considered significant. This throws open an entirely new basin for hydrocarbon exploration from the Neoproterozoic sediments in Rajasthan and other similar prospective basins in India. The palynological assemblage recorded from the studied samples also contains larve of the petroleum fly Helaeomyia (=Psilopa Coquillet) petrolei, known to live in pools of crude petroleum. The significance of the find is discussed in this brief communication.

Abstract

The remains of Pillbug and millipede from the resin lumps associated with the Tertiary sediments Kerala coast are reported here for the first time. These remains have been described as Armadillidium payangadensis sp nov and Polyxenus mecanica sp nov. The resin lumps containing Arthropod remains are Found associated with the Tertiary deposits( Warkalli Formation) exposed at several places along Kerala Coast. The fossil bearing resin lumps have been collected from Payangadi China Clay mine, Cannanore Kerala.

Abstract

Black carbonaceous shale associated with black chert nodules of Infra Krol Formation, Baliana Group yielded diversified assemblage comprising 20 taxa of Organic-walled microfossils (OWM) represented by acritarchs and cyanobacterial remains. Out of these, 16 taxa are reported for the first time from this area which include five genera of acritarchs (sphaeromorphida subgroup) viz. Margominuscula simple, Granomarginata primiriva, Satka colonialica, Paracrassosphaera dedalea, Microconcentrica incrustata, and six genera (sphaerohystrichomorphida subgroup) viz. Baltisphaeridium perrarum, trachyhystrichosphaera vidalii, Gorgonisphaeridium maximum, Micrhystridium echintiatum, M. regulare, M. eatonensis, Archaeohystrichosphaeridium cellulare, A. semireliculatum,Germinosphaera unispinosa; four taxa of the cyanobacterial remains viz. Globophycus rugosum, Bavlinella faveolata, Eomicrocystis inalgica, Tetraphycus hebeiensis, Eophormidium orculiformis belong to Synaplomorphitae subgroup and single genus of VSM viz, Melanocyrillium hexodiadema.

The recovered microbiotic assemblage compares well with the assemblages known from the Terminal Proterozoic sediments. The large sized acanthomoph Trachyhystrichosphaera vidalii, recorded here for the first time, is known globally after. Varanger glaciation and before diversification of Ediacaran biota. An analysis of the recovered microbiotic assemblage in the Infra Krol Formation suggests its autochthonous nature. It was deposited in stable, shallow water, restricted pond or lake which had occasional contact with the open sea.

Abstract

A manganiferous horizon was recorded near Niralkeri, in an intricately folded quartzite-chert breccia-mudstone sequence of the Simikeri Subgroup in the Kaladgi Basin of Karnataka. The nodules collected from this horizon show the presence of todorokite, vemadite and lithophorite in association with quartz and hematite; with MnO-58%.
