After several years of foraminiferal research at ECOPETROL - ICP in Colombian basins including Caribbean areas, the necessity of preserving the knowledge and standardise the taxonomy came-out. Hence the Foraminiferal Collections comprising Cenozoic and Mesozoic taxa were created. In addition, an electronic database with photographs groups all the specimens into categories.
Collections are organised in three main divisions: Taxa, Biofacies and Regional. The first two constituted Reference Collections holding over 500 species of foraminifera, among planktonic and benthonic forms. The latter group encompasses calcareous, agglutinated and pseudochitinous specimens. They are made up of homeotypes, topotypes and a few morphotypes coming from several Colombian basins. Biofacies Collection belongs only to Colombian Caribbean slope and shelf so far.
The Regional Collection comprises more than 5000 mounted micropalaeontological slides belonging to internal research projects over a period of nearly five years. It encompasses picked and/or sorted slides (and related washed residues) from well and outcrop sections in Colombia.
The "Foraminifera Database" was designed to gather the exclusive information to each microslide of the catalogued material, such as locality, sample depth and age, just to mention a few. This database provides also an easy and rapid way to seek for a species, by searching through almost 600 records. Holotype descriptions and figures are available for comparison with optical and/or SEM photographs of the material contained in the Reference Collections as well. In order to keep pace with the incoming large amounts of data from diverse research projects conducted at ICP, the same database framework is being used to construct the whole inventory of microslides of the Regional Collection.
For the previous reasons, we consider our collections a potential repository of new holotypes coming from further research in the area.
Key words: Cenozoic, Colombia, Foraminifera, Holotype, Homeotype, Mesozoic, Foraminiferal Collections, South America, Topotype.
