"The single most beautiful image anywhere on the internet"

There's a big crossover, sure, but I often wonder if everyone who visits Tet Zoo also visits SV-POW! Today is the day we put that to the test. To find out more about this image....

.... you must, by law, go here.

Next: oh no, it's the giant killer opossums!

I've said it before and I'll say it again: if you read Tet Zoo, you're in very good - nay, famous - company. I've lost track of how many famous zoologists, palaeontologists, artists, TV personalities and Hollywood starlets are among the regular visitors. Among the many is Mike Skrepnick, who of…
For, like, the second time in the last six years we're going on holiday. So, goodbye. Back soon. Just received a copy of Gasparini et al.'s Patagonian Mesozoic Reptiles; looks awesome. Anurans, beluwhals, red panda empire, and really, really bizarre new sauropods when I get back. Yesterday I went…
For the full story on all of this, you'll have to nip over to SV-POW! I guarantee you won't regret it. My favourite 'fact' about potto neck spines: they demonstrate a link with the Chupacabras (no, I don't accept this, but some do take it seriously, apparently). Observant readers will have noticed…
If you've been enjoying the series on mesonychians you'll be pleased to hear that it's not completely over. There are a few groups yet to come (though, as we'll see, whether they really are mesonychians or not is controversial. 1000 Tet Zoo dollars* to whomever guesses the names of the groups I'm…

> oh no, it's the giant killer opossums!

Stagodontids (giants at least by mesozoic mammalian standards, but not even marsupials sensu stricto, leave alone opossums)? Sparassodonts?

Cool!

Thylacoleo?

There was a short reference to thylacoleo in TetZoo back in April, but you really can't have too much thylacoleo.

"Thylacoleo?"

That's not a giant killer opossum, more like a giant killer koala or wombat.

Now, then ***I*** was a child I was taught that "opossum," spelled with an "o," was for the American species (criters like the famous cartoon character Pogo the Possum). And that "possum," without the "o," means either the Australian kind or that the speaker is an illiterate redneck. So if you asked me to guess, I'd guess that Darren's next (or next but n-th) post will be about some American type or types, not about a derived Australidelphian like Thylacoleo. But WHICHEVER he writes about I expect to be delighted and educated by it!

Wait, I thought Thylacoleo was a member of the phalanger family -- aren't those Australian possums? Or did he get reclassified?

I once saw a book titled "Possums and Opossums" in a bookstore. It was from the late eighties or early nineties. It dealt with all kinds of extinct and recent metatherians (all called marsupials in the book), not just phalangers and American opossums. There were colour plates depicting reconstructions of *Wakaleo* and other thylacoleonids in the book.
If I remember right, there was a microbiothere depicted on the cover.

Killer opossums must be the borhyenids... In Brazil there's a lot of names for the opossums (Didelphis): gamb�, sarigu�, timbu, mucura, etc...

Is the size of the Quetzalcoatlus correct?

"Wait, I thought Thylacoleo was a member of the phalanger family -- aren't those Australian possums? Or did he get reclassified?"

At least it was a diprotodont, like Australian possums, kangaroos, wombats, and koalas. According to Mikko Haaramo's site recent diprotodonts fall into the Vombatiformes (wombats, koalas, diprotondontids) and the Phalangeriformes (phalangers, kangaroos). Thylacoleonidae aren't part of any of these groups. But of course Aus. possums aren't opossums, and don't really have that much in common with them. So it might have been a killer possum, but certainly not a killer *o*possum.
I hope I didn't spoil anything here.

J. S. Lopes: the azhdarchid in question isn't Quetzalcoatlus but it's bigger, tougher brother from Transylvania, Hatzegopteryx. There's not many fossils to work with, but wingspan estimates of this critter are in the region of 12 m: this gives it a standing shoulder height of 3 m and a similar neck length. What's more, the fragmentary skull remains hint at a skull half-a-metre wide and 2.5 m long. Yowee.

It would be shameless of me to exploit Darren's blog to link to this page for more information, so I won't.

Hold on a second...

That brachiosaurus skeleton came from the outside of the Field Museum in Chicago, as did the elephant. The azdarchid is from one of your earlier blog. I don't know anything about the background picture or the whale skeleton.

Neat image, and an amazing testament the power of modern
image technology...I'll try to visit SV-POW more often.

Mr. Meyers,Mr. Wedel-Nowhere near as big as battleship, and it isn't made of anti-matter either. ( Still pretty
damn impressive. Oddly, it makes me wonder if any smaller
pterosaurs occupied the Tickbird niche... )

Mr. York: Absolute size is hardly species-diagnostic, much less so subatomic constitution. Be aware that you are also arguing with no less a figure than Richard Hing, who will not be pleased at your skepticism. I give thanks that I have not (yet!) suffered his wrath.

Larger pterosaurs occupying the Tickbird niche would need impressively large ticks. One might wonder, parenthetically, if supersonic sauropod tail lashings could be aimed precisely enough to dislodge or discomfit troublesome kopidodons and other vermin.

Would require a time machine. Kopidodon is middle Eocene in age.
