SA scientists find new dinosaur! (pics)
Here’s a story bound to make waves: Scientists at the University of Witwatersrand on Wednesday announced the discovery of a new species of dinosaur, writes Kenichi Serino.
“It’s one of the big jewels South Africa has,” Dr Adam Yates, from the Bernard Price Institute for Paleontological Research, told journalists in Johannesburg.
The dinosaur, Aardonyx Celestae, was named after Yate’s wife, Celeste, who was responsible for removing the bones from its casing of concrete-like rock, the Sapa news agency reported.
“She spent over two years and two pregnancies removing the rock,” said Yates.
The rock also provided the other part of the dinosaur’s name, Aardonyx, which means ‘earth claw’.
Fossils from two Aardonyx were found, one which was seven metres long and the other nine. They are an estimated 195 million years old, dating from the early Jurassic period, and were herbivores.
Due to its underdeveloped bone structure, it is believed that the fossils recovered were from juveniles only between seven and ten years old. An adult Aardonyx may have been larger than thosefound.
Yates said the dinosaur shared traits of evolutionary precursors to the sauropods which dominated the Jurassic period.
Sauropods were plant eaters that walked on four-legs.
Aardonyx, by contrast, walked on two legs but is believed to have occasionally also used its forelegs to walk.
For this reason it was a “living fossil” that would have been old, even amongst other dinosaurs.
“It is in effect a living fossil…it’s a primitive holdover from an earlier period,” said Yates.
However, like sauropods living at the time, Aardonyx grazed by stripping vegetation from branches with its small teeth.
Aardonyx was found on a farm in the Senekal district of Free State. The farm was owned by Cobus Visser who gave his permission for the dig.
It was one of three new dinosaur species found in the area. Also found was a single tooth from a carnivorous dinosaur near Aardonyx’s remains.
“But we don’t know if it killed it or found its carcass and took advantage of a free meal,” said Yates.
He said the carnivore tooth was also an exciting find because of its size, which would be much larger than other carnivorous dinosaurs in the area at the time.
Further fossil evidence was needed before a new species was declared, however.

@Raggy. Possibly because it’s a dinosaur fossil? “They” tend to assume that tree fossils are trees and that human fossils are human. The teeth indicate what it ate.
Wow, what fantastic discovery. carefull analysis of the teeth always tell if its a meat eater or vegeterian.
Why is that whenever they find a fossilized skeleton, they assume it’s a dinosaur? It’s also a presumption that it was a vegetarian.
When I First Read The Head-Line I Thought That They Had Found My Mother-In-Law.( Ha,Ha )
How come we always only find the bones of these dinosaurs?
Perhaps the locals ate them?????
How does an animal use it’s forelegs to walk? It would surely risk a serious stomach turbulance if not attacked by its predetors!!
Gavin,
That’s not a dinosaur, that is the fossil of the red-nose whisky drinker from a town called Manchester.
