Charcoalified Wood of <i>Hopenium pondicherriensis</i> (Dipterocarpaceae) from Neyveli Lignite Formation

Abstract

The Neyveli lignite is one of the largest brown coal field of India, Cuddalore district of Tamil Nadu. The lignite it is one of tertiary formation found in the Neyveli, So far many mega and micro fossils reported from this formation. The Neyveli lignite well preserved and recognizable entities are mainly woody and non-woody tissues of different angiosperm plants, spore and pollen, cuticles of leaves, resins, fungal spores and fungal fruiting bodies. The present study is about the charcoalified angiospermic wood is identified as Hopenium pondicherriensis (Dipterocarpaceae). This is a first report of Hopenium pondicherriensis from the Neyveli formation.

Endocarps of Parinari (Chrysobalanaceae) from the Neogene of Northeastern Thailand

“…Parinarioxylon cuddalorense Awasthi was reported from late Miocene Cuddalore Sandstones near Pondicherry, India, and from the middle Miocene Warkalli beds, Kerala, India (Awasthi, 1969;Srivastava and Aswasthi, 1996;Jud et al, 2016). Parinarioxylon neyveliensis Awasthi and Agarwal was reported from the Neyveli lignite in Tamil Nadu, India, variously considered to be Miocene (Singh et al, 1992) or Paleocene-Eocene (Elayaraja and Kumarasamy, 2019). Parinarioxylon splendidum Trivedi and Ahuja was reported from Miocene-Pliocene deposits from the Siwaliks near Kalagarh, Uttarakhand State, India (Trivedi and Ahuja, 1979).…”
