Three dinosaur burrows have been found in Australia indicating that some of these large reptiles lived in cold climates and hid underground to survive. The remains date back 110 million years , when the Australian continent was closest to the south pole. The place, located about 240 kilometers from Melbourne, has been dubbed Knowledge Creek.
Anthony Martin, a paleontologist at Emory University and a co-author of the discovery, suspects that these structures could be the work of ornithopods , bipedal herbivorous dinosaurs, similar in size to modern iguanas.
According to Martin, "This research helps us better understand long-term geological changes and how organisms adapted when the Earth went through periods of global warming and cooling ." In fact, this same paleontologist found 3 years ago in Montana (USA) the remains of an adult dinosaur and three youngsters of 95 million years old fossilized in another burrow, which indicates that their manufacture could be a custom? Common in both hemispheres and in different species ?.
