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

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.

Keywords

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.
