New research on a vast fossil site in Patagonia shows that some of the earliest dinosaurs, the Mussaurus Patagonicus, lived in herds and suggests that this behaviour may have been one of the keys to the success of dinosaurs The shells, with embryos inside, date back 193 million years to the Mesozoic Era, about 40 million years earlier than previous estimates of the start of herd behaviour.įossilised bones of 80 juveniles and adults were also dug up, grouped by age across an area of about half a square mile on the dry margins of a lake.Įggs and hatchlings were in one area, adolescents nearby and grown ups scattered throughout – typical of a complex, social structure, the team said. Scans show they belong to the same species – a primitive long necked herbivore called Mussaurus patagonicus, according to the team of palaeontologists from the Massachusetts Institute of Technology. More than 100 eggs, complete with embryo remains still inside, have been dug up at a dinosaur graveyard in the Laguna Colorada Formation in Patagonia, Argentina, providing the world’s first evidence of herd behaviour. The remains of 80 juveniles and adults were also found around the same areaĮarly dinosaurs were sociable and moved in herds 193 million years ago – 40 million years earlier than first thought, a new study has revealed.They date back 193 million years and likely belonged to a large dinosaur herd.The eggs were x-rayed and revealed ‘remarkably well preserved’ dino embryos.Researchers have been studying the remains of 100 dinosaur eggs in Argentina.Just buy the game.Early dinosaurs were SOCIABLE and moved in herds 193 million years ago – 40 million years earlier than previously thought, study finds Do not discuss pirating the game, do not ask for how to pirate the game.
