Evidence shows bedform and bar architecture documents rapidly migrating rivers, reflecting geomorphological dynamics.
Sediment analysis indicates characteristics of high-sinuosity and meandering patterns in rivers from 1.2 Ga.
Data from supplementary material includes various figures and tables, enhancing understanding of ancient river systems.
Insights into bedform structures may inform current models of river migration and sediment transport processes.
