Thylacosmilus was discovered in Argentina in 1926 when paleontologists excavated a fossil of an animal that looked remarkably similar to Smilodon. It had two main differences from the saber-tooth cat.

To shed light on this super-predator mystery, Dr Wroe's team of Australian and US scientists constructed and compared sophisticated computer models of Smilodon and Thylacosmilus, as well as a ...

(For comparison, these saber-toothed cats, such as Smilodon, that lived across North America went extinct just 11,000 years ago.) Studying Thylacosmilus has created more questions than answers ...

So long, Smilodon. Hasta la vista ... There was even a marsupial sabertooth named Thylacosmilus. Yet, whether creodont or marsupial, nimravid or machairodont, paleontologists have struggled ...

Results showed that extreme saber teeth, such as those of Thylacosmilus atrox and Smilodon, required up to 50% less force to ...

Thylacosmilus had huge, ever-growing canines, leading people to speculate that it was an even more vicious predator than the placental carnivores it superficially resembled such as Smilodon.

Superficially, Thylacosmilus resembled the saber-toothed cats of the Pleistocene, like the North American icon, Smilodon fatalis. Both have long canines designed to attack large prey, but the ...

At least two species of sabertooths were more muscle than bite, subduing their prey with powerful necks and forelimbs, a new study says. Ongoing research has suggested not. For instance, a 2007 ...

Like Smilodon, Thylacosmilus had highly specialised canines adapted to kill large beasts but until now little was known about the exact way it killed its prey. Scientists took CT scans of fossil ...

"But compared to the placental Smilodon, Thylacosmilus was even more extreme." "Frankly, the jaw muscles of Thylacosmilus were embarrassing. With its jaws wide open this 80-100 kg 'super-predator ...
