Chilesaurus was a small, herbivorous dinosaur from Late Jurassic South America. Despite its unassuming appearance, it is was easily the strangest of all dinosaurs due to possessing traits from numerous dinosaur lineages. The discovery of Chilesaurus has led to a major upheaval in science's understanding of dinosaur evolutionary relationships, to such an extent that even the definition of the word "dinosaur" had to be revised.
