Topic: Thylacosmilus


  
  Paleocraft Thylacosmilus atrox
The Thylacosmilus ('pouch-knife') and its prey lived and thrived during the late Miocene and early Pliocene and are believed to have succumbed to extinction around 2 million years ago.
Thylacosmilus and related species are believed to have evolved into hunters from primitive marsupial insectivores that became isolated when South America drifted away from the rest of the continents.
Thylacosmilus and their type are collectively known as borhyaenids ['meat/food-hyaenids']: the lions, tigers, and bears of their time.

Skull of Thylacosmilus, the famous marsupial saber tooth predator from the Miocene of Argentina.
Marsupials became extinct in North America by the end of the Oligocene, though they continued to do well in South America, which by that time had become separated from North America by an ocean channel (as a result of the ancient supercontinent of Pangea breaking up).
The mammalian carnivore niche in South America was filled entirely by marsupials of genera such as Borhyaena and Thylacosmilus, the latter being an excellent example of a "marsupial saber tooth "cat"".

Didelphis the modern opossum and Thylacosmilus from the Pliocene
This group of mammals is very diverse and has survived from the Cretaceous to the recent by either being isolated from placental mammals or by taking advantage of new niches.
Didelphoidea includes some very large carnivores, such as the saber-tooth marsupial Thylacosmilus, from the Pliocene of South America, which reviles any of the saber-tooth cats, from North America; and the bear-like marsupials such as Borhyaena.

From one of the borhyaenids arose what was probably the most spectacular marsupial hunter of all time; Thylacosmilus, a marsupial sabre-toothed tiger armed with large, stabbing teeth that were probably used to slash the soft throat of its prey.
The teeth were larger, and longer, than those that developed in true cats, and kept growing, unlike those of the eutherian sabre-toothed tigers.
Those marsupials that had managed to carve themselves a daytime niche--the saber-toothed Thylacosmilus and its relatives--were totally outclassed by the eutherian jaguar, panther, ocelot and other members of the cat group, sleek and fast hunters whose physiques had been honed to perfection in the demanding environments of the north.

Although saber tooth cats lived from 33.7 million years ago to 9,000 years ago, the divergence of each species occurred very early on.
The first line of saber tooth cats to become their own species was the cats leading to the species known as Thylacosmilus.
Suprisingly, this marsupial diverged in the late Creatceous and had more similarities to opossums and kangaroos than any feline.

 Classical Values :: In search of missing links....
They are often unfairly stereotyped as boring slothful vegetarians, idiotic kangaroos hopping around (and running courtrooms which railroad people on phony charges), kangaroo wannabee-wallabies, drooling possums which play dead at the slightest sign of trouble, or any number of lesser-known tree climbing things -- all considered "backward" for the mere crime of having a pouch.
You are looking at a realistic model of Thylacosmilus -- a fearsome marsupial which occupied an ecological niche as close to the saber toothed tiger as it was possible to be without actually being a saber toothed tiger!
I think a marauding Thylacosmilus could probably have handled him.

Alouatta sp., a red howler monkey, whose skull is comparable to that of some ornithischian dinosaurs, such as Udanoceratops; note especially the size of the jaw but the shortness of the teeth and the general herbivory of all howlers, despite the size of the canines.
Fleshing out the head of Thylacosmilus, this sabretooth marsupial "lion" strikes a pose.
It is possible that the lower jaw supported a fleshy "sheath" for the sabres when the jaw closed, because the shape of the jaw suggests embayments the teeth would slide along, and flesh would hinder this.

There were marsupial sabretooths as well, including Thylacosmilus in the Pliocene/Pleistocene, twelve to three million years ago.
There was a large family of carnivores, called the nimravids, now all extinct, which produced several sabretoothed forms in the Oligocene era, thirty-six million years ago.

Today the thunder-birds have gone, but the crane-like Seriama that still struts the grasslands of South America is a distant offshoot of their lineage.
By about four million years ago the borhyaenids had given rise to a sabre-toothed marsupial killer known as Thylacosmilus or the Pouch-knife, which lived on the pampas of Argentina.
It was a stocky animal, much like a modern Leopard in size and build.

In 1995 I visited the National Science Museum in Tokyo to see a special exhibition about extinct mammals.
It displayed fossils of animals which were closely related to modern animals; ancient horses, bears, elephants (mammoths), etc., and also of very strange creatures which could hardly be imagined, for example: a large armadillo-like animal with a tail club (Doedicurus clavicaudatus), a tiger-like marsupial with extremely long fangs (Thylacosmilus atrox), and many others.
After the disappearance of the dinosaurs 65 million years ago, the mammals, which up until that time were small, rat-like creatures, started to take on roles which dinosaurs had previously occupied.

Such a close resemblance between the two, which cannot be suggested to have any "evolutionary relationship," completely invalidates the claim of homology.
Another example of extraordinary resemblance between placental and marsupial mammal "twins," is that between the extinct mammals Smilodon (right) and Thylacosmilus (left), both predators with enormous front teeth.
The great degree of resemblance between the skull and teeth structures of these two mammals, between which no evolutionary relationship can be established, overturns the homological view that similar structures are evidence in favor of evolution.

For example, from the well-known and intensively researched North American fossil record of the last 40 million years, only four or five felid or 'felid analogues' are known to fall into this 100-kilogram-plus category.
Powerfully built, with upper canines over 15 centimetres long, Thylacosmilus was the ultimate mammalian predator of its day in Plio-Pleistocene South America.
Still, at around 116 kilograms for the largest known individual, it didn't hold a candle to a big Thylacoleo.

Considering that it was an active predator able to crunch bones, even if not as well as a Tasmanian devil, you betcha.
It didn't have the drop that its distant cousin Thylacosmilus did, but then what other marsupial did?
I'm impressed by the span of the jaw -- looks like it would be able to grasp prey much larger than itself.

 Environmental Record
Cats can also retract their claws while running, which keeps them sharp for combat.
Saber-tooth "tigers" were dominant predators during the last Ice Age (until wiped out by humans), but upper canine "saber" teeth had evolved eight other times in older mammals as examples of convergent evolution, including one marsupial predator, Thylacosmilus.
Part 2 of Advanced Mammal Evolution will follow.
