Echimonoporoopollis, a new pollen genus from the neyveli formation of Jayamkonda Cholapuram well-12 Tiruchirapalli District, Tamil Nadu

Abstract

A new pollen genus Echimonoporopollis, has been recorded from the Neyveli Formation of Jayamkondacholapuram well-12 in Tiruchirapalli District. Tamil Nadu. The genus is represented by two species. viz., E. grandiporus and E. neyveliensis and is characterized by spherical-subspherical shape, single pore and spinose exine. The restricted and abundant occurrence of this genus in the lower zone of the Neyveli Formation (Neocollperipollis spp. Cenozone) may prove vital in correlating this biozone with contemporary stratigraphic units.
