A new study by @jbongers.bsky.social and colleagues suggests nutrient‑rich seabird guano enhanced coastal agriculture, contributing to expansion of pre‑Inca societies in Peru’s Chincha Valley. plos.io/4rSCzcp

In our new research, published in @plosone.org, isotopic analyses of maize align with imagery and historical sources to show how the pre-Inca Chincha Kingdom turned seabird guano (droppings) into a source of wealth and power. @australianmuseum.bsky.social journals.plos.org/plosone/arti...

We're definitely not jealous of @jbongers.bsky.social's fieldwork at Monte Sierpe (Band of Holes)... Last year, Dr Bongers and colleagues published a new theory on the Andean monument's purpose, and it is some of our most-read research of 2025! Read it 🆓 doi.org/10.15184/aqy... 🏺 #Archaeology

Thanks for having me on your show @smitinathan.bsky.social!

Thanks for your interest and watching the segment!!!

Fascinating to read about drone-mapping and the #BandofHoles accounting and trading system in ancient Peru. I just watched a segment on ABC News Breakfast too. @jbongers.bsky.social theconversation.com/a-centuries-...

More coverage of our exciting research on one of the most unique archaeological sites in the Andes!

Research by a team led by the University of Sydney's Jacob Boners (Archaeology) has uncovered compelling evidence that brings us closer to solving the mystery behind one of the most unique archaeological sites in the Andes. www.sydney.edu.au/news-opinion...

Thanks for posting this thread on our research, @antiquity.ac.uk!

Lovely coverage of our research!

What was the purpose of the iconic Andean monument of Monte Sierpe (aka Band of Holes)? New research supports a new interpretation: it was a barter marketplace, later developing into a monumental system of accounting under #Inca rule. 🆓 doi.org/10.15184/aqy... 🏺 #Archaeology @sydney.edu.au
