WASHINGTON – A foot-long piece of bone unearthed in Australia is the first evidence that ancestors of the mighty T. rex once lived in the Southern Hemisphere.

The remains are from an animal much smaller than the famed predator, but add to the knowledge of how this type of dinosaur evolved.

The discovery is reported in Friday's edition of the journal Science by a team of researchers led by Roger B. J. Benson of the department of earth science at England's University of Cambridge.

Did somebody move Argentina? it used to be in south america.

Re: “Dec 17, 2008 ... A short-armed raptor dinosaur that resembles a Tyrannosaurus rex has been found in Argentina.”

“Resembles” is not the same as being a member of the Tyrannosaur family.

[ETL]

“Tyrannosauridae (or tyrannosaurids, meaning “tyrant lizards”) is a family of coelurosaurian theropod dinosaurs which comprises two subfamilies containing up to six genera, including the eponymous Tyrannosaurus. The exact number of genera is controversial, with some experts recognizing as few as three. All of these animals lived near the end of the Cretaceous Period and their fossils have been found only in North America and Asia [until this latest find - March 2010 -etl].

Although descended from smaller ancestors, tyrannosaurids were almost always the largest predators in their respective ecosystems, putting them at the apex of the food chain. The largest species was Tyrannosaurus rex, one of the largest known land predators, which measured up to 13 metres (43 ft) in length[1] and up to 6.8 tonnes (7.5 short tons) in weight.[2] Tyrannosaurids were bipedal carnivores with massive skulls filled with large teeth. Despite their large size, their legs were long and proportioned for fast movement. In contrast, their arms were very small, bearing only two functional digits.

Unlike most other groups of dinosaurs, very complete remains have been discovered for most known tyrannosaurids. This has allowed a variety of research into their biology. Scientific studies have focused on their ontogeny, biomechanics and ecology, among other subjects. Soft tissue, both fossilized and intact, has been reported from one specimen of Tyrannosaurus rex.”

Austroraptor is a dromaeosaur that has short limbs like a tyrranosaur, but is not a tyrannosaur like the newly discovered fossil.

Plate tectonics. look it up.

And why ist thou talking of the Argentine? From the article

The newly reported bone was found by co-author Tom Rich of Museum Victoria in Melbourne, Australia. It was uncovered in Dinosaur Cove in southeast Australia, where occasional fossils were being found.

Probably because of that song lyric, “do not cry for me southeast Australia”.

The Discovery of Dinosaur Cove

These volunteers and many others created this tunnel by first drilling and blasting out the rock above the fossil layer to create a space to stand in. Once that was done, they dug down in the floor to reach the fossiliferous layer using somewhat gentler means, i.e. hack hammers rather than explosives. For every 1 kg of fossiliferous rock recovered, 30 kg of overburden had to be removed. If no fossils were evident underground, the fossiliferous rock was carried outside into the sunlight where other volunteers broke up every rock with hammers and chisels looking for specimens. Far more fossils were first seen outside than underground. Photographer: Frank Coffa

and up to 6.8 tonnes

That's hardly heavier than a particularly large elephant. A 45/70 would stop him without much difficulty.

[ETL]

why ist thou talking of the Argentine?

He mistakenly thought a T-Rex had previously been found in the southern hemisphere (Argentina), when in fact it was actually a dinosaur described only as "T-Rex like" that was found there. Of course many "T-Rex like" dinos have previously been found in the southern hemisphere, including Carcharodontosaurs (Africa), Giganotosaurus (South America) and Allosaurs (just about everywhere I think).

I suspect a lowly .410 shotgun loaded with bird shot would do the trick. One shot for each eyeball... but I wouldn't want to test that theory with my life.

[wendy1946]

There’s no purpose for a 410 shotgun which involves killing anything other than possibly for rats. The 410 is for perfecting skeet shooting skills. That Marlin lever-action 45/70 with heavy ammo really is Amnerica’s most lethal gun. It can drive a bullet straight through a cape buffalo or rhino sidewise or end to end, your choice.
