Across 540 million years, fossil shell records show marine biomass rising hand-in-hand with biodiversity, dipping only during the planet’s great extinctions. Stanford scientists stitched together 7,700 limestone samples to reveal that more diverse seas recycle nutrients better and build bigger food webs—an ancient trend now threatened by human-driven species loss…
