Dinosaurs in Australia –
A collection of tiny fossilized thigh bones are of approximately 2.5 centimeters in length. They are the first available, remains of baby dinosaurs ever found in Australia. According to the Discovery, which was basically in the eastern states of New South Wales and Victoria. Actually, the bones belonged to baby herbivores that were small enough to sit in the palm of a human hand.
Hundred million years ago, Australia was basically further to the South when these babies were playing in their nests. They are also proof that dinosaurs were breeding in southern polar environments within the Antarctic Circle. this was basically written by the authors of a paper in their journal of Scientific Reports.
The New South Wales fossils from the town of Lightning Ridge, they were so small, and according to researchers, they must have belonged to embryonic dinosaurs that weighed approximately 150 grams, and they were basically less than 20 centimeters in length from head to tail. They were just basically about prior to the point of hatching from the egg. This was said by the co-author Phil Bell who was from the Australia’s University of New England.
Groups are given by scientists to these babies dinosaurs –
These babies were the young of wallaby sized dinosaurs, that is basically walked on two legs and had beaks for cropping vegetation. They may have lived in herds, and while the scientists can not be sure which specific species, these babies belonged to. According to some researchers, they would have been animals like Weewarrasaurus from Lightning Ridge, or maybe Diluvicursor or Galleonosaurus from Victoria.
At this time, Victoria was well within the Antarctic Circle and has a similar distance from the South Pole as Greenland, which is from the North Pole today. Though the world was warmer then and there would still have been months of complete darkness and must have freezing temperatures in the winter. Fossilised feathers, which basically have been useful for polar insulation, and there is very little evidence for feathers in this ornithopod group.
