Arrangement of UCMP's Paleozoic and Mesozoic Vertebrate Collections

The primary subdivision is by Storage Age, arranged by their order in geologic time.

Secondary subdivision is by continents arranged alphabetically: Africa, Asia, Australia/New Zealand, South America, and North America.

Tertiary subdivision is by Country arranged alphabetically, except for North America where it is by statearranged alphabetically.

Below that, subdivision is by Formation (alphabetically) and Locality Prefix+Locality Number by prefix alphabetically and then by locality number numerically.  Please 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.


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.
