English: Chilesaurus shows a bizarre mix of traits from various dinosaur groups. While nebulous taxonomic placement is usually the result of scant fossil remains, Chilesaurus has an almost completely known skeleton from multiple specimens. Originally thought to be a basal theropod, it had enlongated forward-facing facing teeth. These indicated that it was herbivorous, and suggested it could be a sauropodomorph. The pelvic arrangement closely resembles ornithischian dinosaurs, further confusing its evolutionary lineage. Other baffling traits include the fact that it had a beak, two-fingered hands, and weight-bearing hallux.
