“I’d suspect it’s one other Australovenator skeleton, however one barely bigger [than previously discovered],” Dr White stated.
“These remains were quite partial, when we had a look they were a slightly different size and shape, but that could be because this animal was slightly older or that there was a male-female [size] difference.”
In whole, the dig crew found greater than 200 bone fragments, a few of them fairly small, and ultimately managed to establish two partial vertebrae and three bones from the palms and toes.
Due to the comparatively low variety of bones they’ll’t affirm a method or one other whether or not this was one other A. wintonensis, but it surely was positively inside the theropod sub-group megaraptoridae, which had been a lot bigger than the velociraptors popularised in Jurassic Park.
This dinosaur would have been about two metres tall and between 5 to seven metres lengthy, with foot-long claws on its highly effective forearms that had been doubtless used to seize and slash prey.
It might have doubtless hunted the quite a few long-necked, herbivorous sauropod dinosaurs that might have roamed the world roughly 95 million years initially of the Cretaceous interval, when that a part of Australia was the swampy shore of an awesome inland sea.
Quite a few fossils of these sauropods have been discovered round Winton, nevertheless.
Dr White stated due to the ratio of huge prey animals to smaller predators, discovering these theropod fossils was extraordinarily uncommon.
“With regard to skeletons, this is only the second one we’ve found [at Winton] in 20-odd years, so that’s quite exciting in itself,” he stated.
“It’s only the third theropod specimen discovered in Australia that consists of more than one bone.”
The primary Australovenator wintonensis fossil was found within the Winton space in 2006, confirming that the massive predators did exist in historic Australia.
Dr White is considered one of dozens of scientists and volunteers who go to Winton yearly to take part in fossil digs, and stated he would like to get his palms on extra theropod stays.
“We’re due to uncover a more complete one but it hasn’t turned up yet. Maybe in the coming years it’ll show up,” he stated.
