Correction: Widespread platinum anomaly documented at the Younger Dryas onset in North American sedimentary sequences

Key Points

• To correct earlier findings regarding the platinum anomaly and its timing during the Younger Dryas of North America.
• Reanalysis of sediment cores from multiple locations across North America
• Elemental analysis conducted to quantify platinum levels
• Geochronological techniques employed to date the samples accurately.
• Confirmed presence of platinum anomaly coinciding with Younger Dryas onset
• Documented increase in platinum levels indicating potential extraterrestrial impact
• Identified changes in sedimentary structures reflecting broader climatic shifts.
