How a sabretooth cat 'bit down'

The sabretoothed cats killed prey with a deep stabbing bite to the throat

The mystery of how prehistoric sabretoothed cats coped with their oversized teeth has been solved in part by a new analysis of the cats' jaws.

To impale prey with these impressive weapons, the famous sabretoothed cats must have opened their mouths wider than any modern big cat, but it was unclear if their jaw muscles were strong enough to do it.
Now the new analysis reveals that the cats' jaw muscles evolved into a specialised pattern, which allowed them to open their mouths so wide.
Details are reported in the Zoological Journal of the Linnean Society.
