The cause of this mass die-out is still debated, though some researchers have pointed to dwindling food resources, possibly driven by warming temperatures and competition with humans, as a culprit. A new study suggests, however, that at least two of these long-gone creatures, sabertooth cats and their feline cousins, American lions, didn’t starve to death.
Big carnivores facing scarce resources often gnaw their prey to the bone and signs of this voracious eating behavior are evident in the wear and tear on their teeth. But the teeth of sabertooth cats and American lions from the La Brea Tar Pits in California have no such marks that would indicate a period of distress before extinction, the new analysis shows.
