If I could choose which dinosaur to bring back. It would be the Anzu wyliei. It was the chick from hell, but hey it would not cause that much harm to humanity.
It is a bird-like dinosaur that feeds on small animals, plants, and possibly eggs. It has long sharp claws, which would be quite a sight. It measures about 3 metres from tail to head. It is a feathered beast, resembling a beefed up Emu. Maybe farmers could use them to eat gophers and other creatures that disturb crops. Thank you for reading.
