Nannotax Enabling nannofossil research

Coccolithophore families - both these families have unusual coccolith structure and no obvious structural affiniteis to other coccolithopohre groups. They have extant members so their affinites will probably bedetermined by molecular genetics in the reasonably near term

• Alisphaeraceae
• Umbellosphaeraceae

The following genera are a mixed group of living and fossil coccolithophores or nannoliths of uncertain affinity.

• Florisphaera
• Gladiolithus
• Hayella
• Minylitha
• Tetralithoides
• Ilselithina
