Saber-toothed cats may sometimes have wielded their formidable canine teeth as deadly weapons to puncture the skulls of rival cats.
It was already suspected that Smilodon cats used their huge canines to take down prey, perhaps by ripping out the preys throat (SN: 3/30/19, p. 20). But some researchers argued that the daggerlike teeth, which could grow up to 28 centimeters long in the largest species, were too thin and fragile to puncture bone without breaking.
But a new analysis of two skulls from Smilodon populator, a saber-toothed cat species that prowled what is now South America, contests that idea, says a team of Argentinian researchers led by Nicolás Chimento. Large puncture holes in the top of the fossil skulls match the size and shape of canines of saber-toothed cats, the researchers report online in the May Comptes Rendus Palevol. Similar injuries are sometimes seen in the skulls of living cats, such as leopards, jaguars and cheetahs, the authors write.
“Smilodon canines were strong enough to penetrate bone and were formidable hunting weapons,” says Chimento, a paleontologist at the Bernardino Rivadavia Argentine Natural Science Museum in Buenos Aires. The skull wounds were probably made during tussles while “fighting for territorialiRead More – Source
