Marine scientists have uncovered how ancient sea creatures adapted to survive mass extinction events. A recent study examined brachiopods and foraminifera, revealing their survival strategies during the Permian-Triassic and early Toarcian oceanic anoxic events.
Researchers analyzed thousands of specimens, discovering significant changes in shell morphology. Brachiopods reduced shell plicae, while foraminifera exhibited thinner shells.
These adaptations likely helped reduce energy expenditure, allowing these organisms to cope with environmental pressures. This research highlights the importance of understanding how marine life adapts to extreme conditions.
