The Neyveli lignite is one of the largest brown coal field of India, Cuddalore district of Tamil Nadu. The lignite 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.

I describe dispersed miospore assemblages recovered from 35 drill-core samples from Höllviken 2, Norrevång 1, and Svedala 1 wells, all in SW Scania, Sweden. Over eighty taxa of pollen and spores, ranging from the Aalenian to the Cenomanian were identified. Four pollen/spore zones have been defined on the basis of key taxa and on the variation in the frequency of miospore groups. The palynofacies analysis indicates that a continental depositional environment prevailed during the Aalenian in Scania. A stratigraphic hiatus existed from the Aalenian then on until the Valanginian, when the depositional environment subsequently became marine. The marine conditions continued until the Cenomanian. A gradual increase in marine palynomorphs is found in the Cenomanian succession, indicating a transgression. On the basis of the palynoflora it is suggested that the vegetation consisted of cycads, conifers, pteridophytes and a very limited number of angiosperms.
