A 190-million-year-old dinosaur nursery with 340 eggs has been discovered, providing an insight into the animals' behaviour from the oldest nesting site ever found. The excavation site in South Africa belonged to the prosauropod dinosaur Massospondylus and predates other nesting sites by 100 million years, according to researchers. It has provided experts with clues and evidence as to the evolution of complex reproductive behaviour in early dinosaurs.
Fascinating discoveries such as hand-prints of the ancient animals have led the scientists to believe the hatchlings remained at the nursery long enough to double in size and the adults returned repeatedly to the same nest. And it is believed there are still more fossils hidden away in the Golden Gate Highlands National Park. David Evans, associate curator of Vertebrate Palaeontology at the Royal Ontario Museum said: ‘Even though the fossil record of dinosaurs is extensive, we actually have very little fossil information about their reproductive biology, particularly for early dinosaurs.
