It's interesting when you think of a rapid succession of adaptive radiation and convergent evolution made a lot of marsupials appear in similar forms to placental mammals, kangaroos being the most notable exception. Thylacaleo being another, almost like it was on the way to be more like a feline but never really made it. Those teeth though are mad. The only thing you can compare them to are dunkleosteous, I can't think of anything else matches those blades.

So it turns out that Sir Richard Owen was occasionally correct.

Koalas are also more closely related to wombats than to other diprotodonts, in fact the superfamily Vombatoidea is the only living superfamily of diprotodonts within the suborder Vombatiformes.

From a purely mechanical point of view, the Thylacoleo incisors seem like they have a more optimal placement for both generating a ton of force and resisting sideways movement than the typical canine teeth. Could still be more optimal to puncture the trachea in two places, but idk.

@Joshua_Hale

Жыл бұрын

If we consider it functionally similar to a beak, it has advantages and disadvantages. The placement does generate more force at a single point, and it is more resistant to horizontal force. However, having two points of penetration helps grip a target more securely, preventing it from slipping wriggling free. Looking at other hunters, this beak-like placement seems to be favoured for animals hunting hard-shelled prey (turtles and dunkleosteous both had a beak-like jaw to hunt arthropods, and many insectivorous birds hunt with their beak), while beaked hunters of soft-bodied prey often use other means to kill their targets (birds of prey typically rely on their claws). However, predators that specialise in mammals, as well as in most fish and reptiles, and do kill with their jaws, have canines that give them two points of control over their prey (virtually all carnivorans and dasyuromorphia that are not insectivorous).

Iirk canines are typically used to hold on to prey not to actually kill. There are a few exceptions such as Smilodon which are speculated to have used their saber teeth to piece the jugular veins of it's victims. So having more attachment points is an advantage which is probably why most carnivores have widely spaced canines.

Thank you again for such a wonderfully researched and presented documentary!

Prehistoric marsupials and Australia in general is such an underrated topic. There's so much uniqueness and convergent evolution at work here that it's a travesty that it's hardly ever spoken about in favor of much more cliche subjects. However, the massive transformative influence that marsupials have had on Australia makes you wonder what was Austalia's biodiversity like before the migration of marsupials happened?

Because it usually happens only once. The first group that evolves to eat meat has no real competition and so quickly filles up all the carnivore niches. Then different species evolve from this starting population to fit those niches even better. A second group that starts evolving in the same direction has to face competition with animals that are already very well adapted to that lifestyle. It's a a bit like a young, newly trained chef trying to open the first restaurant in a town vs. coming to a city that already has many different restaurants with experienced chefs and a good reputation - it is possible, especially if you have some new talent or secret recipe, but it will be much harder.
