Watch a herd of dinosaurs move across a prehistoric landscape. Herbivores graze in herds for safety while carnivores hunt cooperatively — predator-prey dynamics from 65 million years ago.
Dinosaur herding follows the same Boids flocking rules used by modern birds and fish. Predators target isolated individuals, so herding provides safety in numbers — the same evolutionary pressure seen across hundreds of species today.
Click to add herbivores or carnivores. Watch predators chase and hunt. Use sliders to adjust herd size, predator count, and movement speed.
Trackway fossils from the Jurassic Period show dinosaurs moving in coordinated herds, with juveniles protected in the centre — the same protective strategy found in almost every modern herd animal.
