Dinosaur fossil reveals earlier evolution of sauropod long necks
由 AI 报道
A newly discovered 230-million-year-old dinosaur fossil from Argentina suggests that the evolution of long necks in sauropods began much earlier than previously thought. Named Huayracursor jaguensis, the specimen shows early signs of neck elongation in a small, bipedal dinosaur. This finding challenges the idea of a gradual transition in sauropodomorph evolution.
