Aquillapollenites is an extinct morphogenus of Late Cretaceous angiosperm pollen grain. Aquillapollenites was a very large group containing something like 80 total species, but all of them were typified by their triprojectate structure: three processes extend from the equator of the pollen grain and one process extends upwards to each pole, giving Aquillapollenites the shape of a child's jack. This strange shape may improve the buoyancy of the pollen grain. Colpi occupy each terminus of the equatorial projectates, making Aquillapollenites tricolporate.[1]

Aquillapollenities was mostly extinct by the end of the Cretaceous, but a few species survive across the K-T boundary into the Eocene Epoch.[2] North America's northern animal biome approximately correspond with the Aquillapollenites palynofloral province.[3]

It has been suggested that Aquillapollenites is a pollen type produced by an extinct member of the mistletoe family, but this remains uncertain.[1]
