Land Snail with Periostracal Hairs Preserved in Burmese Amber

摘要: Summary Excellently preserved fossils often provide important insights into evolutionary histories and adaptations to environmental change in Earth's biogeologic record. Mid-Cretaceous Burmese amber, for example, is a proven reservoir spectacular findings. Here we document the first record of fossil land snail with periostracal hairs amber. We interpret development as an adaptation tropical forest environment, serving mechanism increase adhesion plants during foraging while collecting transporting seeds process. The present coincides major global radiation angiosperms, main food resource terrestrial snails. As such, expansion flowering likely triggered this and, thus, diversification snails Cretaceous.
