On some species of Ginkgoites from the Jurassic of the Rajmahal Hills, Bihar

Abstract

The paper describes a number of leaf impressions referred to the genus Ginkgoites Seward from Sakrigalighat. The specimens, on the basis of the shape and size of the lamina, can be separated into different species. There are two chief types: (1) Leaves comparatively large, divided into four cuneate segments each of which is again partially divided. (2) Leaves small and divided into four to five linear segments which may again be divided. In both the cases the leaves possess a distinct and fairly long petiole.
