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 DNAKeywords

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.Keywords

The volatile displacement of burnt coals has been compared with that of carbonized coals. A relation has been found between volatile displacement of burnt coals and its chemical composition, i.e., carbon and hydrogen contents.- Record Of Pillbug (Armadillidium) and Millipede (Polyxenus) Remains from the Resin Lumps of Warkalli Formation (Upper Tertiary), Kerala Coast
