Aitor Ederra drew my attention to this painting by Frederik Spindler:
As so often when we look at All Yesterdays-style palaeo-art, the initial reaction is “no way!”, but that’s quickly followed by a more thoughtful “… but why not?”
Well, why not? We have bare-skinned African and Asian elephants, but not so long ago we had wooly mammoths. Even assuming that Giraffatitan was as naked as Loxodonta, why would its polar equivalents not have adapted the ancestral dinofuzz into a thick insulating coat?

Here’s a working version of that link.

That last one really hurts. Here’s the original image, which should have gone in the paper with the interpretive trace next to it rather than on top of it:

Although it would be nice to think that our site views have octupled in the last day because of Mike’s fine and funny posts about what search terms bring people to SV-POW!, the real reason is that we were blessed by incoming links from both pages of this Cracked.com article.
Now, as any person who has ever accomplished anything whatsoever knows, it is super-important to avoid Cracked.com or you’ll still be up 23 hours from now reading, “6 Mind-Blowing Ways that Comedy Writers are Secretly Destroying Your Productivity”. (I’m kidding, that article doesn’t really exist–but if it did, I’m sure it would consist entirely of descriptions and links to six other Cracked articles). But that’s only true because most of the articles there hit the sweet spot at the intersection of funny, surprisingly informative, mercifully short, and well-written. Crack.com would be a more honest URL, but I assume it was taken.
Anyway, I’d like to return the favor, so here’s a list of the 6 SV-POW! Posts Most Likely to Blow the Minds of Cracked.com Readers. If I missed some goodies or recommended some stinkers, let me know–the comment thread is open.
Who doesn’t want to read about the bizarre real-world mystery surrounding what might have been the world’s largest dinosaur? If you’re not sold, consider that the picture above shows a single vertebra that was–or at least might have been–seven and a half feet tall.
The mercifully short version of this much longer post, in which I consider the consequences of the world’s largest animals having the world’s longest cells.
Weapons-grade anatomical pedantry.
Yes, there is a ship in Star Wars: The Clone Wars that is basically a flying dinosaur vertebra. It took us about five weeks to unravel that story–the post linked above has links to the rest of the saga.
Our original linkbait post. Don’t miss the shorter follow-up with more critters.
A deliberately goofy post in which I wax poetic about the largest predatory dinosaur claws ever discovered.
So, that was a big pile of superlatives and Star Wars. If you’re hungry for more substantial fare, you might start with our Tutorials page or our Things to Make and Do series on dissecting and skeletonizing modern animals. We also blog a lot about the evils of obstructive publishers and the need for open access to the scientific literature–you can find those posts on our Shiny Digital Future page.
A parting shot in my desperate quest for attention: this Star Wars ship flying around in the background in Firefly and Serenity is at least partly my fault–full story here. Oh, and my co-blogger Mike Taylor has written an insightful and affordable book about Doctor Who; read about it here.

Hey, remember this? Your bound-for-PeerJ manuscript is like our Mauritian friend here, and the March 1 deadline is approaching like a hungry sailor with a club. So if you still want a voucher, let me know ASAP.

In a recent comment, Doug wrote:
If I want to be a truly educated observer of Tyrannosaurus rex mounts, what 5 things should I look for in a reconstruction to assess if it is true to our current scientific understanding? I’m not talking tail dragging/upright at this point…we are well past that I hope.
If he had asked about Apatosaurus, I could have written him a novel. But it is a point of pride with me not to contribute to the over-application of human attention to T. rex; not only would it be vulgar, it would also be a waste of resources, considering how many people already have that covered. So, you theropod workers and avocational “rexperts”, we’re finally inviting you to the high table. Please, tell us–and Doug–what separates the good T. rex mounts from the crappy ones. Big piles of SV-POW! bucks will be showered on whoever brings the most enlightenment, especially if you adhere to the requested List of 5 Things format.
The comment lines are open–go!

Recently I had the opportunity to give a talk on photographing specimens and preparing illustrations in Jim Parham‘s phylogenetics course at Cal State Fullerton. Jim is having each student (1) write a description of a specimen, (2) run a phylogenetic analysis, and (3) do some kind of calibration on their tree. I think that’s rad.
Anyway, it was fun talk and I wanted to put it up for everyone, but Mike had the idea of posting a batch of slides at a time, to hopefully fire some discussion on different aspects of photography and illustration. So if you’re impatient to see the whole thing, blame him! I will post the whole talk at the end of the post series, and you can find all of the talk posts here.
And now, on with the show.
