Archaeologists from the University of Liège (Belgium) are conducting a new excavation campaign at the Palaeolithic site of Trou Al'Wesse in Modave. This exceptional site provides valuable information about the settlement of the first Homo sapiens populations in north-western Europe around 40,000 years ago. It is also an opportunity for archaeology students to gain practical experience in the field.
- Iron Age site believed to be potential ritual and ceremonial centre for community that also hosted large feasts
- Detailed laboratory examination and analysis of the fragile 2,400 year old cauldrons has revealed new information of their manufacture and long-term maintenance
- Results of the analysis have been used to create a full-sized replica cauldron
- A new display featuring the replica cauldron and story of the settlement will feature in Leicester’s newly opened Jewry Wall: A Real Roman Experience museum
Humans have used psychoactive plants for their narcotic effects for thousands of years. Throughout Thailand, remains of betel nuts, plants used for their stimulant effects, have been discovered at burial sites. To learn more about the practice, an international team of researchers have examined 4,000-year-old teeth and found traces of compounds from betel nuts. This indicates that betel nut chewing has been practiced for thousands of years, if not more, in the country. The study is the first to detect ‘archaeologically invisible’ cues in dental plaque, revealing ancient behaviors and practices that otherwise could have been lost to time.
Decades ago, archaeologists discovered a sticky substance in a copper jar in an ancient Greek shrine. And until recently, the identity of the residue was still murky — is it a mixture of fats, oils and beeswax or something else? Researchers publishing in the Journal of the American Chemical Society have reanalyzed samples of the residue using modern analytical techniques and determined that it’s likely the remains of ancient honey — a conclusion previous analyses rejected.
