Llamas on the Land: Production and Consumption of Meat at Chavín de Huántar, Peru published in December 2016 by Silvana A. Rosenfeld and Matthew P. Sayre in Society for American Archaeology
The results from analysis of a large camelid sample from the La Banda sector of the Middle Formative (1000-500 BCE) Peruvian site of Chavín de Huántar demonstrate that imported ch’arki (dried meat) was not the main source of camelid meat for consumption at the site, as previously thought. The new zooarchaeological evidence from the La Banda sector shows that multiple production strategies occurred at Chavín de Huántar demonstrating the socioeconomic complexity of the people who lived and worked around the monumental center.
The Methuselah of plant diaspores: Sphagnum spores can survive in nature for centuries published in April 2017 by Zhao-Jun Bu, Sebastian Sundberg, Lu Feng, Hong-Kai Li, Hong-Yan Zhao and Hong-Chun Li in New Phytologist
The authors of this study analyzed the viability of Sphagnum spore in peat cores of up to 0.5 m in depth from two peatland microhabitats located at Hani Peatland in northeast China, a 17 km2 transitional mire. The peat core chronology was established using three dating methods: radiocarbon (14C), caesium-137 (137Cs), lead-210 (210Pb). The results show that a high percentage of the c. 170 and 680 year-old spores from cores taken from a hummock and a hollow, respectively, were still able to germinate, and this shows that Sphagnum can form an extremely long-term persistent spore bank.
Translated analytical reports coming soon
Following the launch earlier this year of our new calibration reports that give likelihoods for each calibrated range using the high probability density range (HPD) method, we will soon be reporting results online in German, Spanish, French, Italian, Norwegian, Portuguese, Turkish, Korean, Simplified Chinese, Traditional Chinese and Japanese.
Updates on our secure online results portal
We have been busy making our secure online portal even more convenient for you.
