Advances in ichnological research in Mizoram: Insights, Developments and Future Prospects

Extensive ichnological studies on the Miocene sedimentary succession of Mizoram, particularly around Aizawl have been carried out, have led to the identification of diverse ichnotaxa, the characterization of distinct ichnofacies and the interpretation of depositional environments. These studies have significantly enhanced our understanding of the palaeoenvironmental setting of the region and the broader context of the basin evolution. However, further progress is necessary to address understudied areas, promote interdisciplinary collaboration at both national and international levels and integrate comparative analyses with updated global ichnological framework to enhance the scientific quality of regional studies. The application of ichnofacies and ichnofabric analyses must be rigorously carried out, as these tools are crucial for reconstructing palaeoenvironmental conditions, understanding sedimentary basin evolution and evaluating reservoir potential. Future ichnological studies in Mizoram should emphasize generation of high–resolution data through more detailed and precise field and laboratory investigations, particularly in areas that remain poorly documented. Incorporating geomicrobiological approaches can provide new insights into the biogeochemical processes influencing trace fossil formation. Moreover, employing quantitative methods and functional morphological analyses of trace fossils can enhance our understanding of trace–maker behaviour, palaeoecological interactions and environmental constraints. By adopting these advanced methodologies and broadening the scope of research, future ichnological studies in Mizoram can substantially enrich the regional trace fossil record and contribute significantly to regional and global geological and palaeoenvironmental interpretations.
