New evidence displays that saber-toothed cats may have been considerably much more intense than we originally considered. The cats belonging to Smilodon populator species—who possible utilised their elongated canines to tear through the delicate places on the bodies of their prey—may have also used those people fearsome tooth to stab by way of the skulls of other saber-toothed rivals.

Nicolás Chimento, a paleontologist with the Bernardino Rivadavia Purely natural Sciences Argentine Museum in Buenos Aires, was the guide writer of the paper that examines injuries discovered in the skull of a person saber-toothed cat inflicted by one more who might have been defending territory or battling for a mate.

“Despite the fact that it can’t be ruled out that the accidents were brought on by a likely prey kicking the skull, the sizing, condition and normal capabilities of the accidents propose that they ended up inflicted by the upper canines of another Smilodon specific all through agonistic interactions,” pointed out Chimento et al.

Saber-tooth fangs could grow to virtually a full foot in larger adult cats but ended up formerly thought to have been too weak to penetrate bone without the need of breaking by themselves. Smilodon populator, a native to the South American region of the globe who roamed the earth in the course of the Late Pleistocene interval (~126,000 many years back), is intently relevant to Smilodon fatalis, which was indigenous to North The usa.

Chimento believes that the North American saber-toothed cats could have also made use of their canines to crack the skulls of their rivals however there is no concrete evidence of this—yet.
