Birds are known to be the direct descendants of dinosaurs.

Birds are known to be the direct descendants of dinosaurs.

In any case, the evolutionary origin of their feathers can be traced back to Carnotaurus (a huge carnivorous dinosaur 9 meters long and with teeth the size of daggers).

Looking at the modern cassowary, it is very easy to believe that they are close relatives with the carnotaurus: the Guinness Book of Records calls the cassowary the most dangerous bird on Earth.

A disturbed cassowary can deliver a dangerous kick with a hypertrophied claw.

During World War II, the US and Australian military stationed in New Guinea were instructed not to engage in conflict with these aviancosaurs.
