Dunkleosteus Was Never 33 Feet - And It's Still Terrifying at 13

370 million years before sharks ruled the sea, a 33-foot armored predator with no teeth patrolled the ancient Devonian ocean that would one day become Ohio. Preserved in the fossil record, Dunkleosteus terrelli killed with self-sharpening bony plates that snapped shut in 50 milliseconds and sheared straight through bone. Patrolling this shallow ocean, it was the apex of the Age of Fishes—until scientists quietly changed the numbers on how big it really was. We reconstruct its place in prehistoric marine life by reviewing the fossil record and the scientific revisions that changed our understanding of its true size. Every claim is drawn from peer-reviewed paleontology, exploring how these ancient placoderms evolved and eventually vanished. 0:00 The Ancient Predator of the Shallow Seas 1:40 The Age of Plate-Skinned Giants 4:41 Challenging the Thirty-Three Foot Myth 6:21 Diversity in the Devonian Food Web 8:29 The Collapse of the Armored Empire 🦕 NEW GIANT EVERY FRIDAY Subscribe to explore the lost giants of Earth's history reconstructed from fossils, anatomy, and palaeontological evidence: ▶    / @monstersbeforeus   Monsters Before Us reconstructs prehistoric megafauna and ancient ecosystems from the fossil record.
