Explore the valuable role of macrofossils in sedimentological research through this comprehensive lecture. Learn how to interpret depositional settings, analyze fossil concentration processes, determine paleocurrents, and conduct diagenetic analysis using macrofossil evidence. Discover techniques for fossil hunting, understand deposition rates and abundance patterns across fluvial and aeolian environments, and delve into taphonomy and leaf margin analysis. Gain insights into leveraging various macrofossil types, including lamellibranchs and echinoids, to enhance sedimentological interpretations. Conclude with a discussion on practical applications, field courses, and an opportunity for questions to deepen your understanding of employing macrofossils in sedimentology.
