The Morrison Formation is best known for its abundant and diverse sent hidden biodiversity—that is diversity not counted in any taxonomic dinosaur remains. Exposures of the Morrison provided much of the mate- compilations based solely on body fossils (Hasiotis, 2000, 2002, 2003). rial for the “dinosaur gold rush” in the western US during the last half of For example, the entire record of Morrison insects, a group which must the nineteenth century.

We recognize that the assignment of a to a Morrison Formation until the latter third of the 20th century and remain a tracemaker is fraught with difficulties. As is clear from Hasiotis (2004), major research effort in the formation. there may be several candidate tracemakers for a single type of trace fossil. Over the last two decades, however, more field work and research In such cases, we have listed the fossil under all potential tracemakers when has focused on the questions related to the composition, structure, and so indicated by the author of the source paper. A good example of this is the evolution of Morrison ecosystems.

Significant ad- vances have been made since that publication, and an update is timely. We KINGDOM ANIMALAE have followed the format of our 1998 paper, including both body and trace fossils.

Family Unionidae In contrast to our 1998 paper, we have greatly reduced the number Unio baileyi of personal communications. In part this is because the specimens involved U. felchi have subsequently been described and are now in the faunal list as a for- U. iroides mally-named species. We now feel that personal communications about U. knighti unidentified specimens may be of little use to the reader and might actually U. lapilloides confuse matters. So, while a few personal communications remain, they U. macropisthus have by and large been omitted. We have included fossils that are distinct U. mammillaris but have not been named, using the description given by the author in the U. nucalis source paper.
