It seems someone else has had a go at decyphering the fragmentary tablet K8538 – and the claim is that it describes an impact event in the Tigris-Euphrates marshes. At www.knowledgeminer.eu/climate_papers.html … Seifert and Lemke suggest it describes an event that took place in 2200BC. The tablet itself is dated 1500 years later – but they say it is a copy of an older version. The last decypherment of this tablet claimed an impact in the Alps was being recorded.
