You are in the floodplains of Europe, 125 million years ago.

The damp, fern-covered undergrowth of the Early Cretaceous lands was silent, save for the rustling of small herbivores. You crouched behind a cycad tree, watching a small herd of Hypsilophodon browsing on low-growing vegetation. They were swift, agile animals, moving like modern gazelles with their pointed heads and slender legs, constantly alert.

Just then, the Hypsilophodon froze, their heads snapping up.

Suddenly, something bursts out from the ferns, and the herd scattered. An Eotyrannus charges, using its long legs to cover the distance rapidly. The predator—an early cousin of the massive T. rex—must have been hiding in the undergrowth for some time, its feathers blending perfectly with the dappled light of the warm forest, you realized.

One Hypsilophodon, lagging behind, attempted to bolt, but the predator was too agile. It used its three-fingered grasping hands to pin the smaller herbivore, before delivering a killing blow with its sharp teeth, ending the hunt swiftly, as you continue to watch from a safe distance.
