sabertoothScientists have found that the strong and thick neck of the now extinct sabertooth animal was responsible for its killing powers. Studies show that the strong neck muscles were vital for catching a prey. This was the marsupial that roamed in South America some 3.5 million ago and had the biggest canine teeth when compared to its size.

The present study was led by Stephen Wroe from the University of South Wales, Australia. Wroe explained that the skull of Thylacosmilus was well adapted to resist forces that were incurred by neck-driven bites. This adaption was an imperative for the animal as its long canines that stretched within millimeters of its tiny brain case were very prone to snapping.

The sabertooth’s methodology during hunts was to use its powerful forearms to secure the prey by its neck and then to pierce its long canines into the poor animal’s neck arteries or windpipe. Indeed, such adaptations and techniques, Wroe said, allowed the marsupial to kill animals that were much bigger in size.
