The shells of a large, invasive snail in India can provide exceptionally fine grained records of past precipitation in the region, a new study finds. Kaustubh Thirumalai, a Brown University researcher and co-author of the study, says, “very few proxies give you that sort of [time] resolution in reconstructing precipitation.” He noted that snail shells provide more finely spaced increments of time than do data from bands found in caves, trees, or mollusks, which have been used in prior paleoclimate research.
