    non-bird-footed sub-species dinosaurs, including the dragon, are likely to defend their nests from predators.well-preserved dinosaur nest found in the Gobi Desert suggests that some of these prehistoric animals were inhabited, like birds, to protect their eggs.
    are often portrayed as sociable animals that nest on their own, lay eggs, and then leave," said Francois Therrien, a paleontologist at the Royal Canadian Museum of Paleontology. "But here, we found that some dinosaurs preferred groups, " Therrien said in a recent study published in Geology. They came together and built a nest. The
    found 15 nests and more than 50 egg fossils about 80 million years old. It provides the clearest evidence yet that complex reproductive behaviors, such as nesting in groups, evolved before modern birds separated from dinosaurs 66 million years ago.
    some modern birds and crocodiles nest and lay their eggs in public areas during breeding. Many palaeontologists believe that this "colonial nesting" first appeared in dinosaurs to fight predators. But Amy Balanoff, a paleontologist at Johns Hopkins University in Baltimore, Maryland, says the evidence is not conclusive.
    paleontologists have found fossilized eggs or nests that have gathered together since the 1980s. But study co-researcher Darla Zelenitsky, a paleontologist at the University of Calgary in Canada, said it was difficult for researchers to tell if the eggs were at the same time or just years apart in the same place.
    recently described nest sites are different. The 286-square-metre site is located in southeastern Mongolia, a thin bright red rock that connects 15 relatively undisturbed dinosaur eggs. Some spherical eggs about 10 to 15 cm in diameter have hatched and are partially filled with red rocks.
    researchers say the stripes connect all dinosaur eggs, suggesting that dinosaurs laid them during a breeding season. The outer and internal structure of these eggs, as well as the thickness of the eggshells, point to a non-bird-footed sub-dinosaur, a large group of dinosaurs, including the Tyrannia and Tyrannia. The researchers also estimate that, depending on the number of egg fragments, just over half of the nests have at least one egg successfully hatched.
    , a palaeontologist at California State University, Los Angeles, also believes that such a high rate suggests that some dinosaurs tended to build nests. But he warns that eggs that have hatched often look similar to those broken by arrested eaters.
