💁🏻♀️ TIL: 🦪⏳ Over two decades, scientists #carbon-dated over 7,500 #marine fossils from #ocean beds around the world.
The shared #data showed which environmental factor drives time averaging – the mixing of #fossils from different periods in a single sediment layer. The results show that #sedimentation rate matters most, setting limits on what fossil data can tell us about the past.

I finally got round to adding classic single radiocarbon calibration plots to my #Rstats package {c14}. I think they turned out pretty nice!

A coca leaf buried with a sacrificed Inca child just narrowed a 90-year mystery to under 50. New radiocarbon work points to ~1499 CE, the reign of Huayna Capac, not conquest, but imperial maintenance. #IncaEmpire #Archaeology #Radiocarbon https://www.anthropology.net/p/a-coca-leaf-buried-with-a-sacrificed

RE: https://archaeo.social/@isakroa/109382327541900747
Came across this formulation in a fairly recent paper: "Formation of the site ended between cal AD 1325 and 1410 (note 68% CI dates are considered more probable)", in which they otherwise treat their dates very conscientiously, so I'm quote-boosting this old thread. This is problematic, right?

IOSACal 0.7
IOSACal 0.7 was released yesterday. Here is a quick summary of what’s new. One of the standard plots rendered in the latest IOSACal version. It looks exactly as before. This long cycle was mostly about documentation improvements and some maintenance tasks, the boring but essential work that keeps the project going. Version 0.7 is already available in PyPI and conda-forge. There is an updated version record at Zenodo. All changes were contributed by Stefano Costa. Documentation […] -

@jens2go @ClemensSchmid Unfortunately I have to agree with the reviewers (cool that these are open!) that the chronological modelling in this paper does not support the claims it makes.
In particular, the headline that the structures were "used for up to 429 years" conflates the uncertainty of the #radiocarbon dates with the occupation span of the site.
In reality the radiocarbon data offers no evidence of long-lived occupation (and hence domesticity); it just doesn't rule it out.

New research refines marine radiocarbon corrections for Magdalenian Spain, showing that different shell species age differently. The result is a sharper timeline for coastal Ice Age life and cave occupations. #Radiocarbon #Paleolithic #Archaeology #HumanEvolution https://www.anthropology.net/p/when-shellfish-skew-the-clock
