摘要

Mukherjee D. & Prasad M. 2013. An ebenaceous fossil wood from the Neyveli lignite, South Arcot District, Tamil Nadu, India. Geophytology 42(2): 127 - 133. A fossil wood, referable to the family Ebenaceae, has been recovered from the Neyveli lignite (Miocene) of South India. The fossil wood is characterized by apotracheal parenchyma occurring in 1 - 2 seriate, close, concentric tangential lines at regular intervals and 1-2 seriate heterogeneous xylem rays and shows affinity with the extant taxon Diospyros malabarica (Desr.) Kostel., presently occurring in Indo-Malayan region. The present finding indicates existence of tropical evergreen vegetation under humid climatic condition which was responsible for the formation of lignite in the Neyveli area.
