Morocco's Wrinkle Fossils Hint Deep-Sea Life Predated Sunlight

A Moroccan team found wrinkle-like fossil structures in ancient turbidites, likely formed by chemosynthetic microbial mats buried by underwater landslides. The discovery suggests early life could thrive in deep, dark oceans without sunlight, challenging the notion that photosynthesis-controlled shallow waters were the cradle of life; published in Geology (2025).
