IFPNI provides an authoritative online, open-access, community-generated registry of fossil plant nomenclature as a service to the global scientific community. Dynamic data base documents all nomenclatural novelties (new scientific names of extinct organisms) and associated data, including registration of the scientific publications containing nomenclatural acts and authors generated taxonomic literature in palaeobotany and palaeontology in general, and allied disciplines.
