Abstract :
The present paper describes a fossil
megasporophyll with a pair of ovules from the Deccan
Intertrappean Beds in the Indian state of Maharashtra,
from Marai Patan, Taluka-Jiwati, District: Chandrapur.
Two ovules are oppositely placed and are completely
surrounded by an ovuliferous scale. Integument of small
ovule is multilayered and differentiated into three zones,
viz., outer and inner are sclerenchymatous, while middle
one is parenchymatous. In a large ovule integument is two
layered. Micropylar canal is narrow. It is compared with
modern taxa of Cycadales and Coniferales with the
families like Pinaceae, Taxodiaceae, Cupressaceae,
Podocarpaceae, Cephalotaxaceae and Araucariaceae and
also with earlier described fossil ovules. It is evident from
the study that present fossil megasporophyll resembles
with Coniferoovulites with minor differences and hence
named as Coniferoovulites patanii sp. nov.
