Alfonso Benito Calvo, geologist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) is part of an international team that is currently conducting an excavation campaign at the Tanzanian site of the Olduvai Gorge, specifically in Bed II of the Olduvai stratigraphic sequence, known as the Frida Leakey Korongo site (FLK), where accumulations of skeletal remains of fauna and lithic industry have been found, attributed to Homo erectus.
At this archaeological site, with deposits dated around 1.5 million years, anvils, chips of various sizes and retouched (sharp) objects typical of the Acheulean industry have been recovered. Along with these lithic tools carcasses of large mammals such as elephants and hippopotamuses have appeared. The bones present clearly anthropic fractures or signs created by the edges of the tools when muscular mass was removed, which formed part of the daily diet of this species.
Due to the current campaign, which will last until February 8, more specialized studies may be conducted to carefully analyze each of the recovered items. This information will focus on an interpretation of the life of our ancestors 1.5 million years ago when they invented a new technology, the Acheulean.
In addition to the CENIEH, in this project co-financed by the Palarq Foundation and directed by Ignacio de la Torre, scientists from the Autonomous University of Barcelona (UAB) and the University College London (UCL) has participated
