Arctic fossils reveal complex and diverse Early Triassic marine vertebrate communities

A study of an Early Triassic-age fossil site in the Arctic found complex and diverse oceanic ecosystems, with many marine tetrapod lineages diversifying soon after the end-Permian mass extinction event. The findings suggest that vertebrate evolution paralleled the rapid resurgence of invertebrate life in the Early Triassic.
