A total of six videos are presented showing Mariana Nabais and Rodrigo Portero processing brown crabs (Cancer pagurus), mimicking the potential movements used by Neanderthals living in Gruta da Figueira Brava (Portugal) around 90,000 years ago. Each person processed one raw, one boiled and one roasted crab using their bare hands and a quartz hammerstone. The protocol of the experimentation and results are presented in the paper Nabais et al (2023) published in Historical Biology.
