Palynological study of intertrappean sediments of Mahurzari in Nagpur district, Maharashtra, a known megaflora rich locality, has indicated presence of diverse pollen and spore assemblage. The palynoassemblage includes six genera and six species of pteridophytes dominated by Cyathidites and Lygodiumsporites and four genera and four species of angiosperms. The presence of palynomorphs such as Azolla cretacea, Gabonisporis vigourouxii, Aquilapollenites bengalensis and Farabeipollis suggests a Maastrichtian age. Megafloral remains such as flowers and fruits of Sahnipushpam , fruits of Viracarpon, Indovitis, Baccatocarpon , a coconut like fruit and Palmocarpon , the palm inflorescence Mahurzaristrobus and many fossils wood of dicot and monocot plants are also known from this locality. The recorded flora suggests prevalence of tropical evergreen floristic conditions at the time of deposition of the intertrappean paleolake sediments having volcano-clastic inputs.

来自马哈拉施特拉邦那格浦尔区 Mahurzari 的德干火山相关沉积物的 Maastrichtian Palynoflora:年龄和古环境以及对 Megaflora 的评论
对马哈拉施特拉邦那格浦尔地区 Mahurzari 间层沉积物的孢粉学研究表明,马哈拉施特拉邦是一个著名的大型植物群落区,表明存在多种花粉和孢子组合。孢粉组合包括以Cyathidites和Lygodiumsporites为主的蕨类植物6属6种和被子植物4属4种。孢粉型如 Azolla cretacea、Gabonisporis vigourouxii、Aquilapollenites bengalensis 和 Farabeipollis 的存在表明马斯特里赫特时代。该地区还已知有大花植物遗存,例如 Sahnipushpam 的花和果实,Viracarpon 的果实,Indovitis,Baccatocarpon,像果实和 Palmocarpon 的椰子,棕榈花序 Mahurzaristrobus 和许多双子叶植物和单子叶植物的化石木材。
