“…Conceptual models formed for archaeological purposes will be most useful when founded on realistic processes of coastal sedimentary evolution, and on thorough on-site investigations (e.g., Inda, del Puerto, Capdepont, & Bracco, 2017) that enable researchers to test, advance or reject these models. It is important to consider the nature of the coastal sedimentary environments involved because of their capacity to (a) provide different resources (economic and utilitarian, Bailey & Parkington, 1988;Fitzpatrick, Rick, & Erlandson, 2015), (b) drive different technological developments (e.g., fishing technologies, Colaninno, 2015;Dortch, 1997), and (c) impact archaeological site preservation (Tveskov & Erlandson, 2003;Ward & Larcombe, 2008;Ward et al, 2015). In this paper, we hope to improve matters by promoting a process-based geoarchaeological approach.…”
