Tasmanian tiger's bite was unlike any living mammal's, study finds
Extinct Tasmanian tiger's 'snap' unlike any living mammal's bite
New research reveals that the extinct thylacine, or Tasmanian tiger, had a unique skull and jaw structure adapted for snapping up small prey, not the sheep it was blamed for killing. Its skull was as large as a gray wolf's but slender, resembling a fox's, and functionally similar to fish-catching crocodiles. This suggests the species was wrongly persecuted by colonists who saw it as a wolf-like threat to livestock.
It's a fascinating example of how two animals can look remarkably similar at first glance, while in reality functioning in fundamentally different ways.

I've always found there to be something hauntingly beautiful about the Thylacine. The idea of this solitary hunter with a frighteningly powerful maw and an almost sad face lurking at the bottom of the world send shivers down my spine. It's my hope that one day a pocket of them are found alive out there but I know thats a pipe dream.

“Although similar in size, the thylacine skull (right) proved larger than a gray wolf skull.” This is the caption under an image in which the rightmost skull is decisively smaller than the other two. I think there’s an error. Perhaps the central skull is the one belonging to the Tasmanian tiger, not the one on the right?

> Thylacine crania are far larger than expected for their body mass, as determined by their centroid size (Fig. 3a), and exceed the absolute cranial sizes of far larger marsupials such as red kangaroos (Supplementary Fig. 5). While the thylacine weighs ~17 kgs34, its cranial size (within ±10%) is similar to that of much larger species, between 24.5 and 66.7 kg (Fig. 3a). In contrast, most placental carnivorans that are close to the thylacine in overall cranial shape (Figs. 1b and 2a) are jackals and foxes weighing 6–14 kgs (Fig. 3b). The cranial size of the thylacine is on par with much heavier predators such as the grey wolf, African wild dog (Lycaon pictus), puma (Puma concolor), and leopard (Panthera pardus).

> The large size of the thylacine cranium has not been integrated into interpretations of its function, possibly because morphometric analyses generally remove absolute size43,44 and biomechanical comparisons usually focus on comparative, rather than absolute, generation of bite force44. However, a large cranium counteracts the weaker structure of a long and narrow rostrum by increasing the absolute magnitude of rostral resilience to stress and bite force. This is because larger crania are more resilient to intrinsic and extrinsic loads3,44 and carry more muscle3 compared to smaller crania that share the same shape. It is also possible that the wide zygomatic arch compared to other can […]
