Final answer:
Bulk finds and ecofacts without individual distinguishing features typically do not receive individual catalog numbers but are recorded in bulk on an accession log sheet, which is crucial for environmental reconstruction and understanding past human-environment interactions.
Step-by-step explanation:
Archaeological data that does not receive catalog numbers but are simply recorded on an accession log sheet include bulk finds such as soil samples collected for pollen studies, or other ecofacts like seeds, shells, or animal bones that do not have individual distinguishing features requiring them to be cataloged separately. Instead, they are documented in bulk to represent a snapshot of the environment or context from which they were collected. These ecofacts and bulk materials, while not individually cataloged, are crucial for providing environmental data and for helping to reconstruct past environments and understand human-environment interactions throughout history.
