Abstract

A brief reference is made to the abundant occurrence of fish ossiculiths in the Odhium Clay member of the Utatur Group of the Trichinopoly District, South India. The first fossil otolith (sagittal) from India in the same clay has been shown to be the first Cenomanian otolith of the world. After discussing the relationship of the Indian otolith to the already known Mesozoic otoliths, new Linnean taxa of the rank of family (Lycoclupeidae) , genus (Lycoclupea) and species (menakiae) are instituted. Although the age of the new taxa is Upper Cenomanian, a suggestion as to its probable range in time, from Cenomanian to Dogger, is made for future verification.

Abstract

The paper reports an assemblage of microfossils from the Guddadarangayanhalli Formation of the Chitaldrug Schist Belt. The organic fossils discovered are the oldest fossils from India and they are coming from an age group of 2000-1400 m.y. The assemblage consists of Sphaeromorphitae and Netromrophitae of the Group ACRITARCHA Evitt, and cuticular remains (Spongiophyton Kraeusel). Forms referable to Protoleiosphaeridium Timofeev, Leiosphaeridium Timofeev, Leiofusa Eisenack and Deunffia Downie and/or Bacisphaeridium Eisenack are identified. The scope for refining the stratigraphy of the Archaean Complex is pointed out.
