Abstract The rise of flowering plants from the Late Cretaceous to early Palaeogene (approx. 100–50 Ma) triggered a macroecological transformation on land, propelling a sustained increase in biodiversity. While insect pollinators and herbivores played key roles in this shift, direct fossil evidence of insect pollination of gymnosperms remains scarce. Here, we report two exceedingly rare nitiduloid beetles (Coleoptera) in amber that bear dense coverings of Eucommiidites pollen, attributed to the e
