Ancient giant shark fossils reveal early mega-predator dominance in Australian seas
Berlin, Germany (SPX) Nov 25, 2025 Researchers have identified fossils of a gigantic lamniform shark that lived off northern Australia 115 million years ago. This predator achieved massive body size much earlier in shark evolutionary history than previously known, taking a leading position in ocean food chains with large marine reptiles. The discovery emerged from an interdisciplinary analysis reconstructing size evolution in ancient sharks. Modern sharks trace their origins to the Age of Dinosaurs, with the oldest known lamniform ... read more |
