Invertebrate Paleontology and Paleobotany - Database and Research Tools Cheilosia miocenicus (UCM 4444) Use the links below to search the University of Colorado Museum of Natural History Fossil Invertebrate and Plant Collections. We use the Specify Biodiversity Collections Software. NOTE: There are two catalogs served on this site at the present time, invertebrates and plants. It is possible for more than one specimen to have the same number. Due to a bug in the Specify web interface, if each of these specimens is returned as part of your search, and you click on them to obtain a 'detailed' view of the information, it is likely that only one specimen from one catalog will be shown. We recommend not clicking the detailed view in these instances. All of the information for a specimen is available in the grid-results view. "Simple Search" provides a limited, but useful set of fields by which to search quickly for specimens in our collections. "Advanced Search" allows more fields to be searched simultaneously for more complex searches of the specimens in our collections.
