摘要:
Cretaceous burrows attributable to bees are the earliest known record of activity by those insects and are equivalent in age to, or possibly older than, the oldest known bee body fossil. The burrows consist of vertical shafts from which short lateral corridors and numerous brood cells open. They occur in a lenticular fluvial sandstone in the middle carbonaceous member of the Late Cretaceous (Late Cenomanian) Dakota Formation.
