 The fossilised remains of six infant dinosaurs that died in a volcanic mudflow have been found in China. Researchers say the animals were less than four years old, and probably formed a "creche" composed of babies from at least two different clutches. The Psittacosaurus discovery indicates the animals had started forming social groups much earlier than previously thought, the scientists add. The 120-million-year-old fossils are reported in the journal Palaeontology. Research on the herd was led by Dr Paul Barrett, from London's Natural History Museum. He says the specimens are spectacularly well preserved and together offer a unique insight into the behaviour of the Psittacosaurus, which sported a parrot-like beak. "What [this find] shows is that these animals actually lived in small groups and not only did they live in groups but those groups were made up of individuals from different sets of clutches," Dr Barrett explained. "So, one animal came along and laid a set of eggs somewhere, another one laid another set somewhere else - and individuals from each of those clutches came together to form a herd and that's the first time that we have good evidence of herding behaviour in these early dinosaurs," he told BBC News.
