**Dunkleosteus** This is a 3D model of Dunkleosteus, one of the most powerful marine predators of the Late Devonian period (~358 million years ago). This reconstruction is inspired by modern paleontological interpretations, featuring a streamlined body, heavy cranial armor, and bone-blade jaws rather than true teeth. Unlike older bulky depictions, this version emphasizes a more hydrodynamic, fast-swimming form, similar to modern sharks, while maintaining the iconic armored head plates that made Dunkleosteus such a formidable hunter.
