New research suggests that the size of eggs laid by ancient marine creatures may explain why ammonites went extinct while nautiloids survived the asteroid impact that ended the Cretaceous period.
Scientists developed a new laser-based method combining geochemistry and marine ecology to accurately determine shark age, aiding conservation efforts for vulnerable species like the Speartooth Shark.
A new study reveals that the ability of fish to feed on hard surfaces spurred a significant burst of reef fish evolution around 50 million years ago, leading to increased biodiversity.
