Popis: Excavated nearly five decades ago, the Toyon Bay site (CA-SCAI-564) on Catalina Island remained undocumented until recently (Radde 2015). Now, working with a retained column sample that yielded more than 12,600 vertebrate specimens weighing more than 2,435 g and more than 4,220 g of shellfish remains, we present a comprehensive archaeofaunal analysis that reveals a cyclic progression of three distinct Late Holocene occupational phases supported by use of diverse fish species and a single shellfish taxon, Megastraea (formerly Lithopoma) undosa (wavy top turban snail). Each occupational phase repeats a pattern of escalating use of fish and the wavy top snail over time, followed by abrupt declines in the use of these resources, signaling the onset of short-term inter-occupational hiatuses. Why each occupational phase declined is not known, nor can the nature of the inter-occupational hiatuses be discerned. However, while the overall pattern of subsistence procurement is the same in each phase, propor...
