Morocco Deep-Sea Wrinkles Hint at Ancient Chemosynthetic Life
Researchers in Morocco found wrinkle-like textures in 180-million-year-old deep-sea turbidites that likely formed from chemosynthetic microbial mats, not sunlight-driven algae, suggesting an ancient, dark-ocean ecosystem preserved in the rocks and prompting a rethink of wrinkle structures as indicators of life beyond sunlit waters.
