The influence of marine components in the study area is attributed to seafloor spreading and opening in the Indian Ocean during the Aptian, coupled with eustatic sea-level rise throughout the Aptian–Albian period. The present investigation delineates a marine incursion in the Chintalapudi sub-basin of the Godavari Valley Coalfield based on the occurrence of dinocysts, acritarchs and prasinophytes. Noteworthy stratigraphic marker taxa are recognized as key components in the age assignment of the sedimentary rocks. Sum total of four zones have been recognised in the studied part of the sequence. The oldest zone in the deepest set of sedimentation is identified as Cicatricosisporites australiensis Zone. This zone is assigned based on the first occurrence (FO) of Cicatricosisporites australiensis and Biretisporites eneabbaensis. The next zone, further above in the sequence is Foraminisporis wonthaggiensis Zone. The FO of Foraminisporis wonthaggiensis attested to the initiation of this zone. The third zone is Cyclosporites hughesii Zone recognised by the FO of Foraminisporis asymmetricus. The accessory palynotaxa comprised of Retimonocolpites sp., Tricolpites confessus, Tricolpites sp., Tricolporites sp. and Triporites sp. in the recognition of this zone. The youngest zone of this sequence is recognised at the top of the sequence named Crybelosporites striatus zone based on the FO of Crybelosporites striatus. Palynological analysis places the studied part of succession between the Berriasian to early Albian. The primary objective of this investigation is to explicate the characteristics of sedimentation and paleoenvironmental contexts, with a specific emphasis on utilizing palynofacies and Botryococcus morphotypes as distinct benchmarks. Based on the palynofacies investigation three different depositional regimes have been assigned, which are distinguished as follows: (a) continental (384.30–203.75 m) dysoxic–anoxic basin; (b) shallowest nearshore–inner shelf, marginal marine/brackish water settings; and (c) heterolithic proximal shelf deposition with significant sea transgression (94.50–36.50 m). Unpredictable morphotaxonomical responses across diverse habitats with varying pH levels are projected to enhance comprehension of the palaeoecological and palaeoenvironmental significance of fossil Botryococcus colonies. The uppermost marine part of the sequence denotes the least abundance, reduced size, and ill-defined amorphous forms of fossil Botryococcus colonies. The continental part displays the less abundant but well-defined and fully grown sporadic distribution of fossil Botryococcus colonies; the middle part records its presence with a well-diversified, sturdy structural framework and cellular cup-like structures. The investigation of the Cretaceous strata reveals a dynamic geological history influenced by tectonic activities, including plate drifting and rifting. Present investigation enhances our comprehension of palynostratigraphy, and paleoenvironmental history and facilitates the formulation of models elucidating environmental processes during the Early Cretaceous. In addition, the lipid-rich composition of Botryococcus renders it promising for biofuel production, attracting attention in biotechnology and renewable energy research endeavors.

研究区域海洋成分的影响归因于阿普第期印度洋的海底扩张和张开，以及整个阿普第期-阿尔布期海平面的上升。目前的调查根据甲藻、acritarches 和 prasinophytes 的出现，描绘了戈达瓦里谷煤田 Chintalapudi 次盆地的海洋入侵。值得注意的地层标记类群被认为是沉积岩年龄分配的关键组成部分。在序列的研究部分中总共已识别出四个区域。最深沉积组中最古老的区域被确定为澳大利亚疤痕孢子带。该区域是根据Cicatricosisporites australiensis和Biretisporites eneabbaensis的首次出现 (FO) 来分配的。下一个区域，在序列中更靠上的是Foraminisporis wonthaggiensis区域。Foraminisporis wonthaggiensis的 FO证明了该区域的起始。第三个区是由不对称孔孢菌FO识别的Cyclosporites Hughesii区。附属孢子类群由Retimonocolpites sp 组成。, Tricolpites recognizes, Tricolpites sp., Tricolporites sp .。和Triporites sp。在认可这个地带。该序列的最年轻的区域在序列的顶部被识别为基于Crybelosporites striatus的FO，称为Crybelosporites striatus区域。孢粉学分析将研究的演替部分置于贝里亚期至早期阿尔布期之间。这项调查的主要目的是阐明沉积和古环境背景的特征，特别强调利用孢粉相和葡萄球菌形态类型作为不同的基准。根据孢粉相调查，确定了三种不同的沉积模式，其区别如下：（a）陆相（384.30-203.75 m）缺氧-缺氧盆地； (b) 最浅近岸-内陆架、边缘海洋/咸水环境； (c) 具有显着海侵的异石近陆架沉积 (94.50–36.50 m)。不同 pH 值的不同生境中不可预测的形态分类反应预计将增强对化石葡萄球菌菌落的古生态和古环境意义的理解。该序列的最上面的海洋部分表示化石葡萄球菌的丰度最低、尺寸减小且不明确的无定形形式群落。大陆部分显示出葡萄球菌化石菌落的数量较少，但边界清楚且完全生长的零星分布；中间部分以多样化、坚固的结构框架和蜂窝杯状结构记录了它的存在。对白垩纪地层的研究揭示了受板块漂移和裂谷等构造活动影响的动态地质历史。目前的研究增强了我们对孢粉地层学和古环境历史的理解，并促进了阐明早白垩世环境过程的模型的制定。此外，葡萄球菌富含脂质的成分使其在生物燃料生产方面具有广阔的前景，吸引了生物技术和可再生能源研究领域的关注。
