Revisiting the mammoth bone modifications from Bluefish Caves (YT, Canada)

Evidence of artefacts made of giant sloth bones in central Brazil around the last glacial maximum

“…Santa Elina challenges mainstream claims on peopling of the Americas, in favour of a model in which people first reached out to the American continent during, or even earlier than, the LGM. It agrees with evidence reported from other sites that suggests early human presence in North America, such as the Bluefish Caves in Canada [ 22 , 23 ], the White Sands National Park in NM, USA [ 24 , 25 ], the Gault site in TX, USA [ 26 ], the Hartly mammoth locality in NM, USA [ 54 ], the Chiquihuite Cave in Mexico [ 27 ], which has retouched artefacts similar to the ones found in Unit III of Santa Elina [ 55 ]; and in South America, such as several localities at the Serra da Capivara National Park in northeast Brazil [ 5 , 6 , 9 , 28 , 29 ], Monte Verde II in Chile [ 8 ], and those with claims for human–megafauna interaction, such as El Muaco and Taima–Taima in Venezuela [ 56 ], and Arroyo del Vizcaíno in Uruguay [ 6 ] (although the pre-LGM human presence in the latter has been disputed [ 57 ]). The Cerutti Mastodon site in CA, USA, stands out as an even more controversial site which has been suggested to present evidence for human presence and megafauna butchery during an interglacial period (approx.…”

Archaeology in 2021: Repatriation, reclamation, and reckoning with historical trauma

“…2021; Boulanger et al. 2021; Bourgeon 2021; Eren, Meltzer, and Andrews 2021; Fiedel et al. 2021) and the routes of arrival (Cassidy 2021; Easton, Moore, and Mason 2021).…”

“…The dearth of engagement with Indigenous peoples is clearest in scholarship on the first peopling of the lands now known as North America, where debates continue about the precise dating of various sites (e.g., Araujo et al 2021;Boulanger et al 2021;Bourgeon 2021;Eren, Meltzer, and Andrews 2021;Fiedel et al 2021) and the routes of arrival (Cassidy 2021;Easton, Moore, and Mason 2021). There is also an ongoing focus on ancient DNA analyses to help explain human movement, change, and interaction through time (Liu et al 2021), while ethical challenges remain in working with ancestors (Cortez et al 2021;Supernatant 2020;Tsotie, Fox, and Yracheta 2021)…”

Terminal Pleistocene human occupation of the upper Copper River basin, southern Alaska: Results of test excavations at Nataeł Na’

“…Although the precise timing of initial human dispersal throughout the Americas is still highly debated (Ardelean et al, 2020(Ardelean et al, , 2021Becerra-Valdivia and Higham, 2020;Bennett et al, 2021;Boëda et al, 2021;Bourgeon, 2021;Bourgeon et al, 2017;Chatters et al, 2021;Davis et al, 2019Fiedel et al, 2020;Goebel et al, 2022;Coutouly, 2021;Krasinski and Blong, 2020;Potter et al, 2021;Vachula et al, 2019Vachula et al, , 2020Williams and Madsen, 2020), current genomic analyses predict that a dispersal out of Beringia to temperate North America occurred shortly after the Last Glacial Maximum ~19,000-14,000 calendar years before present (cal BP) (Moreno-Mayar et al, 2018a, Moreno-Mayar et al, 2018bRaghavan et al, 2014Raghavan et al, , 2015Rasmussen et al, 2014Rasmussen et al, , 2015Reich et al, 2012;Sikora et al, 2019;Tamm et al, 2007;Willerslev and Meltzer, 2021). Technological similarities between lithic artifact assemblages recovered from northeast Asia and northwest North America have long suggested a Beringian connection (Dixon, 1999(Dixon, , 2001Goebel, 2004;Hoffecker, 1996;Hoffecker et al, 1993Hoffecker et al, , 2020Pitulko et al, 2017), though the exact nature of this connection still eludes us (Goebel and Hoffecker, 2017;Krasinski and Blong, 2020;…”
