Grin without a cat (- grin) (+ smile)

27 November 2010

This is what happens when I am amused by modern day marginalia, sorry.

I saw the Felids open for the Nimravids back in the early Oligocene.  It was crazy.  Nobody knew what was going on.  We all came out, tie-dyed, ready to groove to the mellow, mental vibes of Holophoneus. Frankly, we were blazed.  Then there were these crazy cats tearing shit up, pouncing, retracting their claws.  It was nuts.  No one knew what to say.

Anyway though, it seems like everyone is totally into cats these days and hardly anyone (not, of course, to say no one) remembers those crazy psychedelic crusaders, the Nimravids.  But we here, doff our bizarrely elongate post-orbital vaults to the pioneers, to the sparkling technicolor carnivores that were catty before catty was cool.

and here’s the part where I sneak in a Fall clip:

Bravo Nick.

Still I don’t think Pantydraco can be beat. Prove me wrong people. I dare you.

Hellasaurus is still available as far as I know.

Just sayin’.

The Last Tapu

23 June 2010

All images from the fantastic collections of the Alexander Turnbull Library

Got to wondering why my four-year-old post about the Huia, a fascinating and sadly extinct bird from New Zealand, was suddenly seeing a deluge of web traffic (well, by microecos standards), broken links and all.

Turns out, a single Huia feather just went to auction in Auckland and fetched NZ $8400 (about $6800 US), setting a new world record for the auction value of a single feather.

Huia feathers were important status symbols among the Maori.  The variation in the number of feathers worn in the hair of the individuals pictured above probably correlates broadly with their social standing, though it is interesting that the number of feathers in the images appears to dwindle with time.  An echo of the Huia’s decline, or a society in peril?  Perhaps a bit of both, certainly the two seem to have something of a common cause in the influx of European invaders, of the two-legged and four-legged variety.

Also noteworthy is that some of the photographs postdate the last confirmed sighting of a wild Huia in 1907.

One suspects the anonymous winner in the recent auction had status on their mind as they cast their bid.  As, I suppose, did their unnamed adversaries that  helped them drive the price up well above the expected NZ $500.  I mean the Huia’s tail feathers have a striking beauty to them, though I can’t help but find them more beautiful when the rest of the bird is attached:

When seemingly deeply vacuous contemporary status symbols like this fetch $10K, $7K for a Huia feather almost feels like an injustice.

But then, I guess that attitude misses the real injustices at work here.

New Evidence Points to Younger Dryas Impact

1 April 2010
Actually, this picture doesn’t have anything to do with the text, but we thought it looked cool. Copyright whomever we stole it from.

The PR office of some university announced the discovery of compelling new evidence that an extraterrestrial impact triggered a pronounced planetary cooling spell known as the Younger Dryas approximately 12.90512 thousand years ago, and ultimately led to the extinction of mammoths and those other things whatever they’re called as well the demise of distinctive Clovis Culture of North America.  Although the Younger Dryas cold interval has been recognized by paleoclimatologists for decades, scientists (well, physicists mostly) have only recently proposed that a comet or asteroid might have been the culprit behind the global cooling.  However, the theory has remained controversial…………………………………………………………….until now.

In a new study published in a scientific journal (you’ll have to figure out which for yourself we don’t “do” citations around here) a global team of experts have stumbled upon a surprising source of compelling evidence for the impact: the absence of compelling evidence.

“The complete lack of solid evidence for an impact at the Younger Dryas is pretty strong evidence that some type of cosmic cover-up has taken place here,” Jones says.  Who is Jones? You probably haven’t heard of him, but he’s an authority on the subject trust me.

“Of course, we can only speculate as to the nature of the super-intelligent space/time faring entities at work here, but I’m going to go with Terminator style robots.  I mean, we’ve seen this kind of thing before.  We’re talking something like Tunguska but times, like, a bajillion.  It was all like ‘sssssheeeew…….KA BOOM!!!!'” according to some other guy who wasn’t involved in the latest research but his e-mail came up when we Googled “comet killed the ice age mammoth dinosaurs.”

That other guy says more research is needed to confirm the non-findings, ” it’s scary stuff man, trippy, scary stuff.  I am SO high right now.”

Source: some press release, I didn’t have time to actually read the paper.

An artist’s depiction of something that almost certainly happened, say scientists.

Luck o’ the Lepospondyls

There once was a beast from Kilkenny

Whose legs were so few there waren’t any

You could call him a snake

But tha’d be a mistake:

‘Though scaly, the beast was amphibiany

Yeah, I know, that last line could use some work.  But, you try rhyming something with “aïstopod.”

The critter in question is Ophiderpeton the closest thing that Ireland has (or rather, has had) to a snake, so far as we know.  It’s quite possible that there were snakes in Ireland before the Pleistocene but so far no one has produced the fossil evidence to prove it.  At any rate, there’s no real reason to blame Roman-Briton missionaries for the depauperate herpetofauna of the Emerald Isle.

The genus was described by T.H. Huxley in 1866 based on Carboniferous fossils found in an Irish Coal Mine.  Huxley wrote a letter to geologist Charles Lyell about the discovery:

My dear Sir Charles–I returned last night from a hasty journey to Ireland, whither I betook myself on Thursday night, being attracted vulture-wise by the scent of a quantity of carboniferous corpses. The journey was as well worth the trouble as any I ever undertook, seeing that in a morning’s work I turned out ten genera of vertebrate animals of which five are certainly new; and of these four are Labyrinthodonts, amphibia of new types. These four are baptised Ophiderpeton, Lepterpeton, Ichthyerpeton, Keraterpeton. They have ossified spinal columns and limbs. The special interest atttaching to the two first is that they represent a type of Labyrinthodonts hitherto unknown, and corresponding with Siren and Amphiuma among living Amphbia. Ophiderpeton, for example, is like an eel, about three feet long with small fore legs and rudimentary hind ones.

In the year of grace 1861, there were three genera of European carboniferous Labyrinthodonts known, Archegosaurus, Scleroceplus, Parabatrachus.

The vertebral column of Archegosaurus was alone known, and it was in a remarkably imperfect state of ossification. Since that date, by a succession of odd chances, seven new genera have come into my hands, and of these six certainly have well-ossified and developed vertebral columns.

I reckon there are now about thirty genera of Labyrinthodonts known from all parts of the world and all deposits. Of these eleven have been established by myself in the course of the last half-dozen years, upon remains which have come into my hands by the merest chance.

Five and twenty years ago, all the world but yourself believed that a vertebrate animal of higher organisation than a fish in the carboniferous rocks never existed. I think the whole story is not a bad comment upon negative evidence. (T.H. Huxley to C. Lyell 1865)

I would love to tell you more about Aïstopods, a bizarre group of limbless amphibians that invented “snakiness” about 200 million years before actual snakes came along, but, I’ve got a St. Patrick’s Day party to go to.  So why don’t I just take the easy way out and divert you over to TetZoo.  Have fun, but please come back safe.

Getting excited for this.  In the meantime there’s always this.

A Trustworthy Pistosaur

8 March 2010

Just to prove that I am, in fact, working:

So it was possible to make a reconstruction of this skeleton with the skull of Pistosaurus.  It has the length of about 3 meters.  There is no doubt, that it represents a primitive Plesiosaur, the same result is also given by the details of the skull.  With exception of interclavicle and clavicle the whole skeleton is drawn from a single individual, the “Strunz skeleton”; the skull is drawn from Pistosaurus longaevus. It is possible that the “Strunz skeleton” is specifically different from the “Geissler skeleton” of which interclavicle and clavicle are taken, but both are Plesiosaurs, and so are both of the same described skulls.  An [sic] eventual difference will be small.  Therefore the reconstruction is a trustworthy Pistosaurus. — Von Huene 1948

Don’t know that I would trust him to give my kids a ride to school….
