A University of Queensland study has shown that snails carry weather records on their backs. The research suggests these records could be used to map prehistoric cyclones. The project examined the rings on the shell of a Biggenden Banded Snail (Figuladra bayensis) collected from Coalstoun Lakes National Park in southeast Queensland. The finding points to a potential new way to study ancient storm patterns.
