The Geological Survey of India (GSI) has annual field season programmes to collect fossil invertebrates from various Phanerozoic horizons in India. All the collections were preserved in the Repository Unit in Kolkata till 1962. Since then, only those specimens that were described and/or illustrated in publications including type specimens for new taxa are preserved there. The types include all forms of fossils such as invertebrates, vertebrates, plants and trace fossils. The type specimens have a continuous numbering, starting from one in the year 1865 to nearly 22,000 at present. The types are catalogued serially in large registers with data on the name of the species, horizon, locality, and publication details. The cataloguing is manually done on large registers. Recently, the data are being changed to metadata standard to be used in computers. The duplicate collections are preserved in the Palaeontology Divisions in the five regions of the GSI, in Hyderabad, Jaipur, Lucknow, Nagpur and Shillong. All the invertebrate fossils collected during the annual field season programmes are identified by the researchers and are included in the field season progress reports submitted to the department periodically. The duplicate specimens are given a regional number that may be alphanumeric in nature. When a fossil from the duplicate collections is described as a new species in a departmental publication or a journal, it is sent to the Repository Unit in Kolkata and will be preserved as the type specimen there, after following the necessary official procedures. The preservation of the all the specimens in the GSI are done by placing them in cardboard boxes in wooden cabinets. No special treatment of fossil is encouraged. Large invertebrate specimens (even type specimens), which do not fit into the cabinets, are exhibited in the Indian Museum, next to the GSI office in Kolkata.
