Kyouryuu Chou Densetsu 2: Darwin ga Kita Movie!

Sixty-six million years ago, Gondwana is home to giants such as Puertasaurus and formidable predators including Maip and Carnotaurus, each species fighting in its own way for food, offspring, and room to survive. Then a danger appears in the sky that no dinosaur can understand: a massive asteroid capable of changing the world in moments. The impact does not end the struggle. It begins a harsher age of fire, cold, and disappearing food. Creatures that ruled the land through size and strength suddenly face an enemy they cannot bite, chase, or escape. Survival now depends on adapting to a planet that no longer resembles the world they knew.
