An Upper Cretaceous paleolake near Jamsavli in the Mandla Lobe of central India has provided a unique opportunity to understand paleoecological conditions during Deccan volcanism. The sedimentary deposits of this paleolake are dominated by freshwater aquatic and semiaquatic flora, such as algae (Pediastrum, Lecaniella), dinocysts (Pierceites deccanensis), diatoms (Aulacoseira), aquatic ferns of Salviniaceae (Azolla), Marsileaceae (Crybelosporites), and pollen grains of Sparganiaceae/Typhaceae (Sparganiaceaepollenites). Such paleolakes, representing a few hundred years of lake history with only aquatic and semiaquatic biota, have rarely been documented from the Deccan volcanic province.

An overview of aquatic and semiaquatic flora from the infratrappean and intertrappean beds associated with the Deccan volcanic province across the Cretaceous-Paleogene shows that the floral communities include algal remains of Botryococcaceae, Chlorophyceae, Chlorellaceae, Cyanophyceae, Hydrodictyaceae, Oedogoniaceae, Ulotrichaceae, Zygnemataceae, dinocysts, and diatoms. Bryophytes are scarce, whereas aquatic ferns of Salviniaceae (Azolla) and Marsileaceae (Marsilea and Regnellidium) are the dominating groups in the intertrappean deposits. Aquatic and semiaquatic angiosperms show less taxonomic diversity and are represented by only five families, namely Nymphaeaceae, Typhaceae, Liliaceae, Acanthaceae, and Pontederiaceae. The ubiquitous presence of macrophytes and microfloral fossil remains of Zygnemataceae (Ovoidites), Salviniaceae (Azolla), Marsileaceae (Crybelosporites and Gabonisporis), and palms, along with paleosol, indicate frost-free, warm, humid tropical to subtropical climates with intermittent dry and wet semi-arid conditions across the Late Cretaceous–early Paleocene.

印度中部 Mandla Lobe 的 Jamsavli 附近的上白垩纪古湖为了解德干火山活动期间的古生态条件提供了独特的机会。这个古湖的沉积沉积物以淡水水生和半水生植物群为主，如藻类（Pediastrum，Lecaniella），dinocysts（Pierceites deccanensis），硅藻（Aulacoseira），丹参科（Azolla）的水生蕨类植物（Azolla），Marsileaceae（Crybelosporites）和花粉Sparganiaceae/Typhaceae ( Sparganiaceaepollenites )的谷物。这样的古湖，代表了几百年的湖泊历史，只有水生和半水生生物群，德干火山省很少有记录。

对白垩纪-古近纪与德干火山省相关的水生和半水生植物群的概述表明，花卉群落包括葡萄球菌科、绿藻科、小球藻科、蓝藻科、水藻科、Oedogoniaceae、Ulotrichaceae、Zygnemataceae、dinocysts 的藻类遗骸, 和硅藻。苔藓植物稀少，而丹参科 ( Azolla ) 和马西兰科 ( Marsilea and Regnellidium ) 的水生蕨类植物) 是跨界矿床中的主要群体。水生和半水生被子植物的分类多样性较少，仅以睡莲科、香蒲科、百合科、刺槐科和柞树科五个科为代表。Zygnemataceae ( Ovoidites )、Salviniaceae ( Azolla )、Marsileaceae ( Crybelosporites和Gabonisporis ) 和棕榈树以及古土壤无处不在的大型植物和微花化石遗迹的普遍存在，表明无霜、温暖、潮湿的热带至亚热带气候，间歇性干燥和整个晚白垩世 - 早古新世的潮湿半干旱条件。
