Interim Register of Marine and Nonmarine Genera
The Interim Register of Marine and Nonmarine Genera (IRMNG) is a project of OBIS Australia designed to assist in the provision of marine species data to OBIS, by permitting the discrimination of marine from nonmarine (and extant from fossil) species records on the basis of the genus name portion of their scientific name (normally, genus + species, or genus + species + infraspecies if applicable). The aim of the project is to (a) assemble as complete a list as possible of the estimated 150,000 extant and 50,000 fossil generic names in current use, plus perhaps 250,000-300,000 synonyms, and (b) flag as many of these as is possible with their marine/nonmarine, and extant/fossil, status. IRMNG also includes a subset of known species names in the world (around 1.4m as at May 2009), with appropriate flags in perhaps 50% of cases.
