New study finds that ancient hominins nearly 800,000 years ago deliberately selected specific basalt sources for different stages of tool production rather than simply using whatever stone was available nearby. By tracing the geochemical “fingerprints” of stone tools to both exposed and now-buried basalt flows, the researchers demonstrated that these hominins possessed detailed environmental knowledge, advanced planning abilities, and long-term technological traditions that were maintained and repeated across generations.

News on the woolly mammoth from Taimering (Bavaria, Germany): The mammoth, discovered in 2020, was buried in a former Ice Age pond after its death. Pollen findings and radiocarbon dating confirm that the mammoth lived and died during the harsh conditions of the Last Glacial Maximum. Cut marks on several ribs suggest that Palaeolithic humans tampered with the carcass. An interdisciplinary research team initiated by SNSB palaeontologist Gertrud Rößner and FAU geographer Christoph Mayr is now presenting the results of its scientific investigations in the Journal of Archaeological Science.

Using a variety of samples and methods, the researchers were able to differentiate which microorganisms were already present in the body during his lifetime and which only colonized it after his death – both during the time in the glacier and over three decades of preservation. In samples of internal tissue, the researchers were able to detect genetic material from bacteria belonging to Ötzi’s original gut flora. A surprising finding is the presence of cold-adapted yeast species, likely originating from the glacial environment, that have persisted on Ötzi’s body to the present day. These cold-tolerant yeasts may also hold potential for industrial applications. The study was published in the reputable Microbiome journal.
