Baby Sea Snail Fossil Found Inside Mother’s Shell
Researchers in Taiwan discovered the first fossils of five freshwater mollusk species from the Early Pleistocene, including rare evidence of a juvenile snail shell inside its mother's shell, indicating ancient live birth behavior. This finding sheds light on the early biogeography and reproductive strategies of freshwater snails in East Asia, highlighting Taiwan's role as a migratory corridor during glacial periods and providing crucial insights into the evolution of freshwater biodiversity.
