First peoples 15,000 years older than thought? https://t.co/0KoZBqYumo ![](https://pbs.twimg.com/media/Edi8bGRXkAE2I1g.png) - [View Tweet](https://twitter.com/johnhawks/status/1285987137029058562) ### View Tweet > @nature A second paper by @labecval and @tommyhigham puts together chronologies from more than a dozen pre-Clovis sites, building more support for a long timeline of occupation during the Last Glacial Maximum (26,000-19,000 years ago) https://t.co/MJShMBhKue ![](https://pbs.twimg.com/media/EdjDIj4XsAUiqST.png) - [View Tweet](https://twitter.com/johnhawks/status/1285992304872914947) ### View Tweet > Really helpful 3D model of Chiquihuile excavation is open access on @sketchfab from @CFArdelean and @Cambridge_Uni Devlin Gandy, shows depth and contours of deposit, stratigraphy and sampling locations. https://t.co/uHHEjdyp85 ![](https://pbs.twimg.com/media/EdjEm_NWoAE86XG.jpg) - [View Tweet](https://twitter.com/johnhawks/status/1285994020725051393) ### View Tweet > My early read on this is that it is important work and I want to see more. However, I have a trust deficit for @nature on this topic, after 2017 when the journal hyped the Cerutti Mastodon site. Work on Chiquihuite funded by the same group. https://t.co/Vk0iuOWecQ ![](https://pbs.twimg.com/media/EdjH6dbWkAYfb8P.png) - [View Tweet](https://twitter.com/johnhawks/status/1285997658579120128) ### View Tweet > The accompanying perspective by Ruth Gruhn might have been an opportunity for @nature to at least acknowledge the last time they claimed oldest occupation of Americas, and reflect on state of field, but no mention at all. Cerutti is erased from map! https://t.co/F4WWvOaOj4 ![](https://pbs.twimg.com/media/EdjLPjxWsAMp3yE.png) - [View Tweet](https://twitter.com/johnhawks/status/1286001261029064705) ### View Tweet > @nature I regret having to stick Cerutti into this thread about really interesting new work. But I'm puzzled. How can @nature editors print these new papers without either citation or retraction of a 130,000-year-old occupation date published in their own journal? - [View Tweet](https://twitter.com/johnhawks/status/1286004128481792001)
