Core Findings: Skull Shape Reveals a Unique Biting Strategy
Researchers from Flinders University and the University of Melbourne examined 225 thylacine skull specimens alongside 60 modern carnivorous mammals. Their three-dimensional shape analysis showed that the thylacine’s skull was disproportionately large for its ~17 kg (37 lb) body—comparable to the skulls of predators weighing 54–147 kg (120–325 lb). The long, narrow snout and a reinforced “terminal rosette” near the canines would have enabled rapid, high-impact snapping bites, a mechanism suited to subduing small, agile prey such as bandicoots rather than large livestock.
Background & Context: From Colonial Myths to Extinction
European settlers in Tasmania quickly labeled the thylacine a “wolf-like” predator of sheep, a perception that fueled a bounty scheme from the 1830s to 1914. Over several thousand animals were killed, and habitat loss compounded the decline. The last known individual died in Hobart’s Beaumaris Zoo in 1936. Contemporary accounts noted little concrete evidence that thylacines significantly impacted the sheep industry, but the myth persisted and justified lethal control.
Data & Statistics
- Body mass: average thylacine ? 17 kg (37 lb).
- Skull size: comparable to predators 2–4 times heavier (54–147 kg).
- Specimen pool: 381 anatomical landmarks measured across 225 skulls from 60 species.
- Jaw mechanics: longer jaws increase tip speed; the thylacine’s skull could open up to ~80°, allowing a fast, forceful snap.

Verbatim Quotes
- “Thylacines were hunted because of myths that they were ferocious predators of livestock, when there was little evidence for this. Their extinction is a story of ignorance and lack of respect for Australia’s unique wildlife and its Indigenous custodians,” — Vera Weisbecker, Flinders University researcher
- “The thylacine’s similarity in appearance to gray wolves contributed to an assumed reputation as a livestock predator,” — Flinders University
- “Even though the average thylacine may have weighed only half as much as the average wolf, its vastly oversized skull is about as large as a gray wolf’s skull,” — Dr. Douglass Rovinsky
- “Many crocodiles and predatory fishes have long, fast-snapping jaws used to catch agile prey like fish,” — Vera Weisbecker
Conflicting Reports & Gaps
Earlier biomechanical studies suggested thylacine jaws were ill-suited for holding large prey, but they lacked a comprehensive comparative framework. The present work fills that gap by directly contrasting thylacine skull morphology with a broad sample of extant carnivores. Direct evidence of diet (e.g., stomach contents or coprolites) remains unavailable, so the precise proportion of small versus medium prey cannot be quantified.
Why It Matters
The research reframes the thylacine not as a “sheep-killing wolf” but as a uniquely adapted marsupial predator whose extinction was driven largely by human misunderstanding. By highlighting how misconceptions about an animal’s ecology can precipitate its loss, the study offers a cautionary example for contemporary conservation efforts, especially in Australia, which records the world’s highest mammal extinction rate.
