A life-sized Australovenator is set to wander about Sydney's Centennial Park as part of Science Week.

The Australovenator, meaning southern hunter, is believed to have roamed Australia 95 million years ago, and has been brought back to life by Erth designers for Science in the Swamp.

While only a few bone fragments have been found of the Australovenator, it was believed to be two metres tall and six metres long.

Only partial remains have ever been found of one Australovenator, including teeth, ribs, and partial forelimbs and hind limbs.

The artefacts are on display at the Australian Age of Dinosaurs Museum of Natural History in Winton and were studied by vertebrate palaeontologist Scott Hocknull, who is senior curator in geology at the Queensland Museum in Brisbane.

Having so few clues as to what the dinosaur might have looked like, Scott Wright, artistic director at Erth, turned to the paleontological experts for help in constructing his replica.

"We made contact with Scott and the museum at Winton to better understand the Australovenator," Mr Wright said.

"I think palaeontology is a science of the imagination."

Mr Wright explained that prior to the discovery of the Australovenator, the Tyranosaur that came from the Otway Ranges and other species found in the Strzelecki Ranges were considered two different species but now it is thought they all might be related to the Australovenator.

"The one in the Strzelecki Ranges was an ankle bone and they were able to construct an entire animal from it, and there was a hip bone down in Dinosaur Cove," Mr Wright said.

These artefacts now match up very closely with an Australovenator, and more bones have been found in the past six months.

"The great thing about palaeontology is there are always more surprises around the corner," Mr Wright said.

"It is reasonable to assume that there were Australovenator-type dinosaurs living up the entire east coast of Australia."

Erth's re-imagined Australovenator will roam Centennial Parklands in an attempt to make science accessible to children.

Vanessa Barratt, manager of community programs at Centennial Parklands, said the program was designed to make science fun for families.

"This event will demonstrate both the importance and the fun of science," Ms Barratt said.

As part of the weekend activities local beekeepers will demonstrate how honey is made and harvested, the physics and chemistry teams from the University of New South Wales will run demonstrations, and Australia's first road-legal solar car will make laps of Grand Drive.

Among all the activities the Australovenator will be the showpiece attraction.

"I'm really proud of what we've been able to create," Mr Wright said.
