20. The Eldest Dinosaur
This familiar-looking creature is named the eoraptor, which means “dawn stealer”, and it is the oldest dinosaur ever found–about 228 million years old to be exact. The creative name was given to the species because it lived during the early days of the dinosaurs, hence the dawn part, and it was a carnivore. The predator was about the size of the modern day German Sheppard, and the first fossil was found in Argentina, in 1991.
