Sporae dispersae of the Lignites from Cannanore beach on the Malabar coast of India

Abstract

In this paper sporae dispersae of the Cannanore lignites have been described. For taxonomic purposes we have made use of the rules of the International Code of Botanical Nomenclature. It was necessary to create some new genera and several species, because our forms do not agree with most of the forms which till now have been studied from the Indian Tertiaries. We suppose that the youngest Tertiary has, till now, not been studied, and that our lignite perhaps belongs more or less to the Upper Miocene or Pliocene while the forms described till now are probably of Lower Miocene.

The present position and problems of Tertiary palaeobotanist in India

“…Rao (1956) has given a comparative account of the pollen and spores from these deposits. Further palynological investigations have been carried out by Navale (1962b) on Neyvelli and by Potonie & Sah (1960) on Cannanore lignites. These pollen and spores have mostly been classified artificially and their identification with modern plants is either doubtful or not knovm at all.…”

Palynology of the Mesozoic sediments of Kutch, W. India. 7. Reworked Permian pollen from the Upper Jurassic sediments - a discussion

“…This leads to the inference that Permian sediments extended as far as Kutch and have been since eroded away and redeposited in the Jurassic times, or the Permian fossils are probably derived from the Rajasthan Permian outcrops. The occurrence of Permian pollen in the Cannanore lignites studied by Potonie and Sah (1958) also are of significance. There are no Lower Gondwana outcrops in this area or in the near vicinity.…”

“…Dijkstra (1949) recovered distinct Westphalian megaspores from the Cretaceous sediments of South Limburg. The same author (1950) Potonie and Sah (1958) illustrated and named typical saccate pollen from the Cannanore lignites. Cannanoropollis, a new genus described by them, is a typical Permian fossil met with in the Permian continental deposits (VENKATACHALA & KAR, in press and others).…”

Sporae dispersae of Jabalpur stage, upper Gondwana, India

“…A complete account of the Sporae dispersae has been given here. The recovered genera and species have been arranged according to the artificial system of classification proposed by Potonie (1956Potonie ( , 1958Potonie ( & 1960 and Dettmann (1963).…”
