It is time to satisfy Australotitan cooperensis, a brand-new types of huge sauropod from Eromanga in southwest Queensland. Australotitan, the “Southern Titan of the Cooper,” called from where it was discovered, has actually been clinically explained by paleontologists and personnel at Queensland Museum and the Eromanga Natural History Museum.
The fossilized skeleton was initially nicknamed ‘Cooper’ after the neighboring Cooper Creek where it was very first found by the Mackenzie homeowner and excavated with Queensland Museum in 2007. Finding ‘Cooper’ has actually altered the lives of the Mackenzie household and has actually caused the facility of the Eromanga Natural History Museum.

Australotitan came from a group of dinosaurs referred to as the titanosaurians, which were the last enduring group of long-necked sauropods and the biggest recognized land-dwelling animals to have actually ever existed. Australotitan is now the biggest recognized dinosaur types from Australia, making it the biggest land animal to have actually ever strolled in wilderness Queensland and sits within the top 10 to 15 biggest dinosaurs worldwide. It is approximated to have actually reached a height of 5 to 6.5 meters at the hip and length of 25 to 30 meters – as long as a basketball court! It might have weighed anywhere in between 23 and 74 loads, the equivalent of 1400 red kangaroos!

The research study discovered that all 4 of the sauropod dinosaurs that resided in Australia around the very same time (96 to 92 million years ago) were more carefully associated to one another than they were to other dinosaurs discovered in other places. To check Australotitan was a various types, its’ bones required to be compared to the bones of other types in Queensland and internationally. Not precisely a simple job when handling vulnerable and extremely heavy bones that are kept in museums 100s to 1000s of kilometers apart.
For the very first time, the group utilized brand-new digital innovation to record each bone in 3-D and compare them to the bones of its closest loved ones. Many of these digital ‘cybertypes’ will form part of Queensland Museum’s digital collection powered by Project DIG, a collaboration in between Queensland Museum Network and BHP.

The digital recording procedure has actually likewise caused some amazing discoveries. It has actually been discovered that numerous of ‘Cooper’s’ bones were squashed by the steps of other sauropod dinosaurs. This can be seen in a sauropod trample zone discovered throughout the excavation of ‘Cooper’. The group discovered a rock-shelf, practically 100 meters long, representing a sauropod path. The footprints of sauropods have actually been maintained stomping through the mud and even the bones of another smaller sized sauropod in the soft ground. This work has actually been forming interesting research studies in dinosaur trace fossils around Queensland.

The clinical publication marks a seventeen-year long conclusion of the collaboration in between Queensland Museum and Eromanga Natural History Museum paleontologists, geologists, fossil preparators, and most significantly volunteers. Australotitan contributes to the growing list of distinctively Australian dinosaur types found in wilderness Queensland, and simply as significantly showcases an absolutely brand-new location for dinosaur discovery in Australia.

Stay tuned for more behind the scenes stories of Queensland dinosaur discoveries!
Project DIG is a collaboration in between Queensland Museum and BHP that will scan our collections and digitize our research study for individuals worldwide.
