The Last Day of the Dinosaurs
Instinct drives the Troodon back to their prime hunting spot, the watering hole, where the last remaining Charonosaurus is drinking. The Troodon are desperate for food. One of them has the confidence to attack. The Troodon runs to theCharonosaurus and leaps on it. It  starts slashing at its neck. The Charonosaurus is still too exhausted to run. Suddenly, the Charonosaurus crashes to the ground, crushing the Troodon to death under its weight. The remaining Troodon starts eating the dead body of its companion.
