Normapolles
Normapolles is an extinct pollen group that arose in the Cenomanian (Late Creteaceous). Normapolles persisted until the early Oligiocene Epoch[1] (Tertiary Period) but were reduced in diversity by the early Eocene Epoch[2]. North America's southern animal biome approximately correspond with the Normapolles palynofloral province.[3]
Normapolles is characterized by a triangular amb and an internally complex tricolpate pore structure with deep pore canals[4]. Normapolles grains have been found inside fossilized flowers of the walnut family.[5]
