10 Dangerous Prehistoric Birds


What you need to understand is that these birds do not exist anymore. They went extinct along with the dinosaurs (some after them and some quite near to our time). I am sure you must be familiar with the most dangerous birds in the modern world so I decided to create a list about the birds that would haunt the skies, waters and grounds in the pre-historic world. Many different things were considered while compiling this particular list including speed, size and prey. I hope this list proves informational and educational. Enjoy the read!
