> 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 canids, particularly in larger thylacines (Fig. 4e), plays a role in buttressing the jaw joint against the leverage of the long jaw3,45, but this remains to be tested. Overall, the large size of the thylacine cranium thus indicates a specific mechanism of prey capture and/or immobilisation optimised for fast, high-impact bites whose force was dissipated across a large volume of cranial bone.
Far worse from my perspective is that it's not a fixed citation that it's not falsifiable. It's just a mutable, generalized source, which is stochastic in nature.
Just an aside on the design rather than the content:
I was wondering for a while about the greenish and yellow bars on the margins of the page, but I'm pretty sure that those are padding to make the document work well on both US letter paper and A4 at the same time! The text area is A4 proportions, so if it were printed, zoomed to size on that paper, the sidebars would simply disappear.
No doubt this is a common technique that I'm just noticing for the first time.
This is so similar to human decision-making though. First I my innate experience to approximate to what I expect is right, then I map that to the truth.
It's the same for so many things:
- reading documentation (what do I expect this function to be called?)
- finding clothes in a shop (something long-sleeved and light)
- picking the fridge for dinner
- finding a book in the library...
so many analogues where I'm not coming cold to a choice.
Genuine question - are you copying the Claude phraseology for effect (in which case you captured it brilliantly), or is there a more mundane explanation?
Exciting! I needed this last week, and now here it is. Thanks.
I share the annoyance about phone detection previees over-promising. But I'm pleased this comes with perspective correction and lighting correction together.

This does not answer the question - it doesn't say "No." or that images are permanently deleted from server on burn expiry, only that there are (currently) limits. So slightly worrying that there might be selective retention.
Because every time, they want it to be the next big thing.
