LOOKING out over an expanse of scrubby sagebrush, it is hard to imagine that the high desert in eastern Oregon was once home to large creatures that resembled sabre-toothed cats. The land here is mostly dry and grassy, punctuated by sharp hills. There isn’t a lot to crouch behind while waiting to ambush prey, and little in the way of trees to climb or sharpen claws on: in some places, the only sign of plant life is a layer of lichen on the rust-coloured slopes. But it wasn’t always like this.
This was part of the territory of the nimravids, ancient beasts also known as false sabre-toothed cats. Fossilised remains indicate that for more than 12 million years,from Florida to New Mexico and up beyond what is now the Canadian border. Then, around 23 million years ago, they disappeared. The trail went cold, and the fossil record suggests that there were no cats on the continent for the next 6.5 million years.
