Scientists have discovered the oldest known saber-toothed predator, a 270-million-year-old gorgonopsian therapsid fossil.
They belong to the evolutionary lineage that would give rise to the first mammals 50 million years later. They were warm-blooded animals like modern mammals, but, unlike most of them, they laid eggs.
Before dinosaurs walked the Earth and tens of millions of years before the first mammals appeared, distant mammal relatives with long, serrated canine teeth were the dominant carnivores on land.
