Sabre teeth — the long, sharp, blade-like canines found in extinct predators such as Smilodon — represent one of the most extreme dental adaptations in Nature. They evolved at least five times ...

Imagine a saber-toothed predator—but instead of being a big cat, it’s a marsupial. Thylacosmilus was a bizarre prehistoric mammal with huge fangs, yet it carried its young in a pouch. How did this ...

Over millions of years, sabre teeth evolved repeatedly in different groups of carnivorous mammals, marsupial relatives like Thylacosmilus and “false” sabre-tooth cats such as Barborofelis. The most ...

Predators have evolved sabre teeth many times during the history of life – and we now have a better idea why these teeth develop as they do. Sabre teeth have very specific characteristics: they are ...

We can study animals from all over the world thanks to science, but what about those that no longer exist? The list of extinct mammals could go on for ages, but each animal has a unique story. With ...

Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with ...

The newly discovered fossils, dating back to roughly 5 million years ago, could have implications for human bipedalism, researchers say. Reading time 3 minutes Paleontologists recently revisited a ...

A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow ...
