The international team was made up of Jasmine Vieri and Marcos Martinón-Torres at @UCamArchaeology, Fernando Montejo at @el_icanh and @MCarreroPazos @UniversidadeUSC. Funded by @ERC_Research (REVERSEACTION project) (6/6) arch.cam.ac.uk/news/no-bosse…

The readoption of the systems could offer low-cost, locally governed solutions to flooding and drought in present-day La Mojana, which currently experiences a water management crisis (5/6)

The low labour costs revealed by the study suggest the work was most likely locally-led and cooperative rather than directed by a hierarchical authority. It could be achieved by the local populations in 0.7-1.5 months, or half a single dry season (4/6)

To shed light on the social structuring needed for their construction, we developed new methods to quantify the associated labour costs, mapping a 500-hectare portion of pre-Hispanic field systems at an unprecedented level of detail (3/5)

The pre-Hispanic field systems of La Mojana in the Colombian Caribbean are so vast you can see them from a plane at high altitude. It was traditionally assumed that powerful rulers must have ordered and managed such an ambitious infrastructure project (2/5)

New textile research from REVERSEACTION! doi.org/10.1007/s10816-025-0… 🌟New method for assessing quality and complexity of archaeological textiles 🌟 Microscope analysis of pre-Hispanic cotton mantas from three regions of Colombia #openaccess #archaeology #textileresearch

The result? We can start to identify real and meaningful differences in how different ancient communities crafted vessels with unique shapes and recipes 🏺 Stats is not just for spreadsheets, it can also tell us stories of human creativity too! #WorldStatisticsDay #Archaeology

📈 MANOVA tests (to test whether identified ware clusters really mean something) #Statistics

🎨 PCA plots (to reduce the many variables we take under consideration and look for trends across pottery styles, dates, and archaeological sites)

🌀 Elliptical Fourier Analysis (to translate the curves that make up pottery shapes into equations!) #3Darchaeology #EFA #Pottery

📊 #WorldStatisticsDay meets Ancient Pottery! Did you know we use statistics to study archaeological materials? Our open access paper in Open Archaeology reveals new insights into pottery from pre-Hispanic Nariño by turning vessel shapes and paste compositions into numbers...

We’re hiring! REVERSEACTION are looking for another Research Assistant to join the team, specifically focused on #archaeometallurgy RT to spread the word! #archaeology #jobalert #academiajobs

And on Sunday, the latest on prehispanic goldwork in Colombia #SAA2025

At the #SAA2025? Come to say hi to some of the Reverseaction team! First on, Thurs at 11 on gold and heterarchy
