Abstract
The approach included a comparison of the composition of fossil insect faunas to the modern regional faunas, and a preliminary analysis of living packrat diet preferences. As in other Quaternary insect fossil assemblages, hard-bodied (well-sclerotized) taxa, especially predatory and scavenging beetles, are dominant. The ecological composition of fossil insect assemblages is skewed in comparison with the modern regional fauna, but the abundance and diversity of the fossil faunas is sufficient to allow paleoenvironmental reconstructions to be made
