Mass extinction didn't affect marine ecosystems: Study
Researchers studying fossils from the Late Triassic mass extinction, where 50% of Earth's species were wiped off 201 million years ago, have found marine life did not fundamentally change when compared on a 70-million-year span. While the event had a "big impact" on the number of species, none of their lifestyles completely disappeared, which preserved the marine ecosystem, said researchers.
