The dinosaur was not big.
In Australia found opalinereverie fossils that appeared to belong to a dinosaur, previously unknown to science.
In Australia, scientists have found opalinereverie fossils belonging to a previously unknown dinosaur species. He was named Weewarrasaurus pobeni – in honor of opal fields, where they found the fossils and the man who gave the fossils to the scientific community.
It is reported that the discovered species lived about 100 million years ago during the Cretaceous period (it began around 145 million years ago and ended about 66 million years ago). This, as noted, the first open view of dinosaurs in the Australian state of New South Wales over the last 100 years.
The only observed fragment Weewarrasaurus pobeni – lower jaw with teeth. Based on this fragment, the scientists were able to tell about the ancient animal quite a lot: for example, the dinosaur was not large – not larger than a dog of medium size. On the basis of teeth and shape of jaws paleontologist Phil bell (Phil Bell) from the University of new England determined that a new type to ornithopoda the infraorder bird-hipped herbivorous dinosaurs.
According to the researchers, although in Australia, apparently, lived just one or two major ornithopoda – muttaburrasaurus (Muttaburrasaurus is a genus that includes only one known species) and another dinosaur that is now being studied by specialists – this territory seems to have been home to a larger number of smaller types. This, as noted, very different from the situation in America, where a small plant-eating dinosaurs had to fight for food with such giants as Triceratops and alamosaurus.
Thus, new types, including Weewarrasaurus pobeni, allow you to learn more about what features had a variety of dinosaurs in different parts of the world. Now, as stated, bell, along with other researchers working on other apelsinovaya fossils.
The study was published in the journal PeerJ, a brief account of the results of the work according to the portal ScienceAlert.
