The Oldowan lithic industry represents the earliest known evidence of efficiently and expeditiously produced flake stone tools (Toth, 1985; Braun et al., 2019; Reti, 2016; Stout et al., 2019). Complex technological strategies were employed to produce these artefacts compared to earlier hominin stone tools, and potential organic tool-use behaviors inferred via parsimony with non-human primates (Braun et al., 2019; Boesch et al., 2020; Delagnes and Roche, 2005; Gürbüz and Lycett, 2021; Harmand et al., 2015; Lombard et al., 2018; Plummer et al., 2023; Proffitt et al., 2023a, 2023b; Stout et al., 2010; Toth and Schick, 2009). Consequently, the emergence of the Oldowan can still (cf. Leakey, 1971) be argued to reflect a behavioral and evolutionary shift within the hominin lineage, although the nature and species-associations of any changes have become less clear in recent years (Bobe and Wood, 2021; Braun et al., 2019; Hovers, 2012; Lewis and Harmand, 2016; Plummer et al., 2023). Nyayanga, located in the Homa Peninsula of Kenya, has recently emerged as an important archaeological and paleontological site yielding evidence of Oldowan stone tools and butchered fauna dating to between 2.595 and 3.032 Ma (Plummer et al., 2023). These findings not only represent the earliest currently known occurrences of the Oldowan but also greatly expand our understanding of its early geographic distribution. Further, some lithics at Nyayanga were found alongside Paranthropus molars, challenging prevailing assumptions regarding Oldowan species-associations and providing a rare instance of Early Stone Age (ESA) hominin fossil and lithic remains in close association. The co-occurrence of cut marked fauna and flakes, including those excavated in direct contact with hippopotamid remains, further distin guishes Nyayanga as an exceptional ESA occurrence extending hominin dietary and technological behaviors “similar to other Oldowan assem blages” into the Pliocene (Plummer et al., 2023: 563)
