Thylacosmilus is an extinct genus of saber-toothed metatherian mammals that inhabited South America from the Late Miocene to Pliocene epochs.Though Thylacosmilus looks similar to the "saber-toothed cats", it was not a felid, like the well-known North American Smilodon, but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to ...
A new point-to-point bite model is introduced in the article by Andersson et al., showing that for saber-tooth cats, the depth of the killing bite decreases dramatically with increasing prey size. [10] The extended gape of saber-toothed cats results in a considerable increase in bite depth when biting into prey with a radius of less than 10 cm.
The biggest skull of a Siberian tiger from northeast China measured 406 mm (16.0 in) in length, which is about 20–30 mm (0.79–1.18 in) more than the maximum skull lengths of tigers from the Amur region and northern India, [11] with the exception of a skull of a northern Indian tiger from the vicinity of Nagina, which measured 413 mm (16.25 ...

The skulls of many sabre-tooth predators, including machairodonts, are tall from top to bottom and short from front to back. The zygomatic arches are compressed, and the portion of the skull bearing facial features, such as eyes, is higher, while the muzzle is shorter. [30] These changes help to compensate for an increased gape. [31]
A 13,600-year-old mastodon skull was uncovered in an Iowa creek, state officials announced this week. Iowa's Office of the State Archaeologist said in a social media post that archaeologists found ...
An adult specimen of Hoplophoneus discovered in Badlands National Park, South Dakota, in 2010 by paleontologist Clint Boyd et al. was found to have bite marks on its skull from the teeth of another adult individual of Hoplophoneus. From examination of the wounds, it was found that the animal had been wounded by its rival's saber-teeth.
