The Holocene mud-flats of Formby Point, at the mouth of the Mersey estuary in northwest England, have long provided information about their palaeoenvironment. Now they yield a more direct evidence — in the form of preserved footprints — of the people and animals that frequented the foreshore.
A lead weight was recovered between 2.2 and 2.4 m depth in stranded beach sands at the southern end of Fraser Island. Its isotope values indicate a close affinity with lead from mines in France. Pumice found with the lead occurs elsewhere at sites dated 480±100 y BP and 520±75 y BP, and one fragment appears to be Loisels Pumice, for which a similar radiocarbon age has been reported from New Zealand. The data are difficult to assess but suggest that the lead weight could have reached this ancient beach between 1410 and 1630 AD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
