C'mon @nytimes, that wasn't a "challenge" to scientific orthodoxy (whatever that means) - it's been clear from the very beginning that none of the #radiocarbon samples presented for an extremely old #pyramid at #GunungPadang came from archaeological contexts.
Pigati et al have redated a deposit from New Mexico that contains human footprints. The original ages, derived from freshwater plant seeds, suggested the humans were there during the Last Glacial Maximum, over 20,000 years ago. This proved controversial, so they redated the deposit by radiocarbon dating pollen, and optically stimulated luminescence. These techniques are far more challenging, but confirm the original age determination. #Radiocarbon#IceAge#HumanMigrationhttps://www.science.org/doi/full/10.1126/science.adh5007
This is our #introduction post for all new followers. We are a grassroots research project investigating #Viking Age and #Medieval#archaeology#dogs and #horses in Ireland and Britain. We are using cutting edge technqiues like #aDNA , #isotopes, #bones measurements (size/shape analysis) and #radiocarbon dating on dog bone samples. Our website is www.vikingdublindogs.ie and we are running a crowdfunding campaign to raise costs of #dating at the moment. If you can help please do and please RToot

How it started and how it's going, Latvian #hillfort in Lelindricas edition. The sequence of uncovering wooden constructions of a rampart in our test pit (1 × 3 m).
At first we thought it was just a burnt tree trunk. Then it became clear we were dealing with woden construction. Now we hope for at least #radiocarbon dates if not some #dendrochronology.
