Great for killing, and for research: the lethal fangs of saber-toothed cats
Extinct for close to 10,000 years, the saber-toothed cat, Smilodon fatalis, still inspires passionate debate among palaeontologists. Foremost: how did it use its most distinguishing feature? Playfully animated, The Deadliest Tooth spotlights the US palaeontologist Jack Tseng’s research into Smilodon fatalis, including why he believes its formidable fangs were used for attacking rather than scavenging, and the surprising amount of information palaeontologists can now deduce from just a few fossils, including how saber-toothed cubs might have lived millennia ago.
