Arrangement of UCMP's Cenozoic Vertebrate Collection

The primary subdivision is by continents: Africa, Asia, Australia/New Zealand, South America, and North America.

Secondary subdivision is by Storage Age arranged by their order in geologic time. For Africa and Asia the Storage Ages are the epochs and their standard subdivisions (early/late or early/middle/late). For Australia/New Zealand it is by now-outmoded faunal ages that broadly correspond to local faunas.  For the Americas, the appropriate Land Mammal Ages (NALMAs and SALMAs) are used.

Tertiary subdivision is alphabetically by Country, except for North America where it is alphabetically by state. Mexico is treated as a single "state" in this scheme, but Canadian provinces appear individually.

Below that, subdivision is alphabetically by Formation and Locality Prefix+Locality Number, numerically arranged within a given prefixPlease note that localities starting with prefixes other than a 'V' precede the more common V-localities.

Within locality, specimens should be arranged taxonomically, following Romer's classification.
 

Special cases:

The Hell Creek Fm. in Montana, the Rancholabrean of North America, and Wasatchian of Wyoming
 
Due to historical confusion about the appropriate age of mixed assemblages that occur in the Hell Creek Formation, some localities can be found in both the Puercan and Maastrichtian parts of the collection.  Eventually this will be fixed, but be sure to double check both areas for specimens.

Because few Rancholabrean sites come from named formations, localities are organized by State, County, and Locality Prefix+Locality Number.

Due to the large number of Wasatchian sites in the Wasatch Fm of Wyoming, these have been further subdivided by county, specifically Lincoln, Sublette, and Sweetwater Cos.
 

Drawer Arrangement

Ostensibly, specimens are arranged in the drawers by locality, and then taxon within locality, moving in rows from front to back.  Some parts of the collection live up to this ideal, but many drawers became misarranged when the collections moved.  Here is a diagram showing how it should be.  The numbers show the order in which the specimen trays should go.  Help to reach this ideal!  Click on it to get a page-size version for printing.
