Out of the many birds out there, I think the most interesting candidate for a reverse engineering project would be the cassowary. The reason for this is because the cassowary is already VERY dinosaur-like in appearance. One look at its eyes and you see the eyes of a dinosaur. Also, the cassowary has powerful scaly legs and feet tipped with sickle-shaped claws like a raptor. Just like a raptor, when the cassowary is provoked it delivers strong kicks that have enough force to kill. In addition to those kicks, the cassowary’s claws are sharp enough to gut a grown human, which is something a Velociraptor would do. Cassowaries can run up to 30 miles per hour and jump six feet in the air. All of these traits combined make the cassowary one of the most dangerous birds in the world. Their diet consists of fruit, mice, lizards, frogs, and carrion, all of which makes them omnivores. Imagine how this animal would look if it was retro-engineered back into a true dinosaur. I will keep this in mind as I brainstorm.
