Early Bird Knocked Off The Top Spot
A dinosaur fossil has been found in China that has been dated at around 155 million years old, disproving previous theories about Archaeopteryx, which is 150 million years old and for 150 years had been assumed to be the oldest bird on earth. The beaked and crested reptile, which was about the size of a chicken and weighed less than 2lb, was part of a subgroup of the theropod class of dinosaurs which also included Archaeopteryx and small clawed carnivores such as Velociraptors. Scientists say that the newly found fossil had long sturdy forearms that suggest it was airborne when hunting, just like a bird. Dr Xu Xing of the Chinese Academy of Sciences in Beijing said that his team's findings, if confirmed, would force experts to reassess current assumptions about how modern birds evolved.
