“…Thackeray (1988), for example, finds very few shellfish in the HP levels at Klasies River and an overall decline across the MSA II and HP levels. There was also a sharp decrease in the density of shell over time during the pre-SB and SB phases at Blombos Cave Langejans et al 2012). Shell densities also declined over time in the pre-SB contexts at Pinnacle Point (Jerardino 2010;Jerardino and Marean 2010).…”

“…In their recent analysis of the shellfishing activities at Blombos Cave, Langejans et al (2012) also find shifts in species prevalence between the pre-SB and SB phases. While they characterize the shellfish species preference during the MSA at Blombos as generally focused on high-ranked species in mid-tidal zones, they find that infratidal species with the highest return rates were mostly limited to the earliest pre-SB phase (M3).…”

“…Although temporal scales for archaeological assemblages are often longer than ideal for ecological studies, shell middens around the globe contain substantial evidence that human harvesters impacted the size structure and relative abundances of exploited populations (Jerardino 1997(Jerardino , 2010Langejans et al 2012;Mannino and Thomas 2002;Parkington, 2008;Sealy and Galimberti 2011;Tonner 2005;and others). Nevertheless, factors such as species interactions and trophic level dynamics, and changes in oceanographic temperature and sea level complicate anthropogenic induced effects of predation and its clues in the archaeological record (see Bailey and Milner 2008;Dayton et al 1998;Mannino and Thomas 2002).…”
