A new dinosaur species that lived 125 million a long time back has been uncovered from a fossil located in Victoria.

The dinosaur, which is believed to have lived in the Australian-Antarctic rift valley was so smaller it was very likely the measurement of a wallaby, in accordance to scientists from the College of New England in NSW.

Identified as Galleonosaurus Dorisae, it is just the next dinosaur of its variety to be determined from the 125-million-yr-outdated rock platforms found southeast of Melbourne. At the time on a time, the place was a densely forested valley with a 4000-km chain of volcanoes to the east, scientists say.

But as the Earth’s plates shifted and continents broke aside the natural environment has lengthy due to the fact disappeared.

“This land has now vanished, but as ‘time-travellers’ we get snapshots of this outstanding planet by using the rocks and fossils uncovered together the coastline of Victoria,” direct writer of the examine Dr Matthew Herne stated in a assertion.

Dr Herne stated that the existence of the Galleonosaurus Dorisae in the Victoria area “confirms that on a world wide scale, the variety of these smaller-bodied dinosaurs experienced been unusually superior in the historic rift valley that the moment prolonged involving the spreading continents of Australia and Antarctica.”

When smaller in stature, it is very likely that the Galleonosaurus dorisae — whose identify refers to the condition of the dinosaur’s jaw — “would have been agile runners on their highly effective hind legs,” Dr. Herne additional.

“The jaws of Galleonosaurus dorisae contain youthful to experienced people today — the initial time an age array has been determined from the jaws of an Australian dinosaur.”

Prior to getting Galleonosaurus Dorisae, the only other dinosaur located in this place experienced been Qantassaurus intrepidus. “However, the myriad of vertebrate fossils gathered from Flat Rocks indicates that even further dinosaurs await discovery,” the study’s summary reads.

Whilst Qantassaurus intrepidus was a in the same way-sized dinosaur, it fed on distinct crops, which Dr Herne thinks “would have authorized them to coexist.”
