Bronteroc

Bronterocs are non-sapient animals featured in the 2021 film Don't Look Up. They appear in a mid-credits scene 22 740 years after the events of the film, in which they attack human survivors landing on their planet.

Biology
Bronterocs are large, quadrupedal hexapods displaying avian and mammalian traits. On their heads they have a powerful beak for a mouth, as well as a pair of eyes, nostrils, and pointy ears. Their four legs and pair of graspers end in three, clawed digits. Most of their fur displays hues of brown and blue, but whitens below the neck, limb endings, and dorsal stripes. The posterior sides of their heads and bodies grow vividly red, large feathers.

They are adapted to oxygen levels 9 % higher than those found on Earth. They inhabit at least one biome on their planet, grazing on its lush, mildly forested grassland. While their diet is not specified, judging by the way they attacked the human survivors they are either territorial herbivores or omnivores.
