Possible lungfish tracks could push back animal migration onto land by 10 million years



Summary

Fossilized tracks discovered in Poland suggest that animals may have ventured onto land 10 million years earlier than previously believed. The tracks, tentatively attributed to lungfish, date back 395 million years, during the Devonian period. If confirmed, this discovery would rewrite our understanding of the evolution of land-dwelling vertebrates. While other animals like arthropods had already adapted to terrestrial life, these tracks point to earlier experiments in terrestrial locomotion by vertebrate ancestors like lungfish, potentially driven by the need to find new food sources or escape predators in aquatic environments.
