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 article.

Now, as any person who has ever accomplished anything whatsoever knows, it is super-important to avoid 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. 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 Readers. If I missed some goodies or recommended some stinkers, let me know–the comment thread is open.

Amphicoelias vert reconstruction by Mike

1.How big was Amphicoelias fragillimus? I mean, really?

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.

long nerves of sauropods

2. Oblivious sauropods being eaten

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.


3. The sauropods of Star Wars

Weapons-grade anatomical pedantry.

Umbaran starfighters

4. CONFIRMED: the Umbaran Starfighter is an Apatosaurus cervical

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.


5. SV-POW! showdown: sauropods vs whales

Our original linkbait post. Don’t miss the shorter follow-up with more critters.

Is that your flexor tubercle, Saurophaganax, or are you just hungry to see me?

6. Friday phalanges: Megaraptor vs Saurophaganax

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.

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.

Bird vertebra diagrams

January 10, 2014

bird neck note sheet

I made these back in the day. The idea was that you could print them out and have them along while dissecting bird necks, so you could draw on the muscles.

bird neck note sheet - LEFT - all three views

It’s basically one drawing of an ostrich vertebra, morphed in GIMP and stacked to simulate articulation. All of the ones in this post show the vertebrae in left lateral view. If you need right views, flip ‘em in GIMP or heck, I think even Windows Explorer will do that for you. The one above has dorsal views in the top row, lateral view in the middle row, and ventral views in the bottom row.

bird neck note sheet - LEFT - double lateral

Here’s a sheet with two rows in lateral view, the idea being that you draw on the more superficial multi-segment muscles on one row, and the deeper single- or two-segment muscles on the other row.

bird neck note sheet - LEFT - 12 cervicals

A version with 12 vertebrae, so you can map out the often complicated patterns of origins and insertions in the really long muscles. How complicated? Well, check out this rhea neck with the M. longus colli dorsalis and M. longus colli ventralis fanned out.

That’s all. Have fun!


As a nice little perk–presumably for being early adopters and users of PeerJ–Mike and I each have been given a small number of referral codes, which will allow other folks to publish in PeerJ for free, as long as the papers are submitted by March 1, 2014. Here’s the scoop, straight from the monkey’s mouth:

If you have colleagues who would like to publish at PeerJ, then we want to give them the opportunity to try us out for free. Therefore, as a Published PeerJ Author, we are providing you with 5 unique ‘Referral Codes’ (which expire on March 1st) to distribute to your colleagues. Each code entitles the recipient to an entirely FREE PeerJ publication. They simply need to quote your referral code in the “Notes to Staff” field, when they submit to PeerJ, and as a result they will be able to publish that article for free (assuming it passes peer-review). Please disseminate these codes to colleagues who you feel will use them, but please make sure that they realize that this code is only valid for submissions made before March 1st, 2014.

Note that this is alongside the current promo wherein, if you post a preprint to PeerJ PrePrints (which is a smashing way of getting fast feedback, or at least it was for us), that manuscript can be published in PeerJ for free, as long as it is formally submitted before January 1, 2014. So if you can get the lead out before the end of the year and don’t have an allergy to fast feedback, you don’t actually need one of these codes.


So. If you’re not a PeerJ member but you have a manuscript that you’d like to send to PeerJ before the first of next March, let us know and we’ll hook you up with a referral code. If you’re fairly sure you will use one but aren’t ready to ship yet, let me know and I’ll set one aside for you, with the proviso that I can give it away if we’re getting close to the deadline and you’re not realistically going to make it.

If we get more takers than codes, we’ll figure out some fair way of choosing who gets a code, probably randomly. I will be strongly biased toward people without big paychecks* or institutional support, like grad students and postdocs. (If you’re an undergrad, you can already publish in PeerJ for free, at least for the duration of the pilot program.) So if you’re a grad student or postdoc with a serious plan to get published, speak up and you’ll go to the head of the line. So if you let us know why getting a code would benefit you, you’re more likely to get one.

* I know in academia none of us think we have big paychecks, but compared to most grad students and postdocs, those of us with steady full-time employment are living the dream. I’m trying to reach the folks for whom the $99 lifetime membership fee would be a genuine impediment.


As is apparently the usual thing now when I’m writing about PeerJ and don’t have any images of my own queued up, I’ve borrowed images from Brant Bassam’s astoundingly cool to spice up this post. Explicit permission to reproduce the images with credit can be found on this page, which is coincidentally where these images themselves are from. Get on over there and prepare to lose some time looking at sweet stuff.

Update! Five more Golden Tickets available!

As noted in the comment below, Heinrich Mallison also has five PeerJ vouchers to distribute to deserving causes. So if Matt and I run out, the options are still open. Feel free to contact Heinrich directly or to go through us if you prefer.


In lieu of the sauropod neck cartilage post that I will get around to writing someday, here are some photos of animals London and I saw at the Arizona-Sonora Desert Museum this Sunday morning.

In chronological order:


Mountain lion, Puma concolor


Black bear, Ursus americanus, which taxon has also graced these pages (and my desk) with its mortal remains.


Bobcats, Lynx rufus. These two play-fought for a while. Watching them was the highlight of the morning, and maybe the highlight of the whole trip.


Gray fox, Urocyon cinereoargenteus. This guy just paused here for a moment, but I am super happy with the chiaroscuro effect.


Javelina, Pecari tajacu. Sunday evening we saw a couple of wild javelinas alongside one of the roads on the west side of Tucson–only the second time I’ve seen them in the wild.


Coyote, Canis latrans. Now these guys I see all the time–on my own street, even, some mornings.


Great Horned Owl, Bubo virginianus. This one flew right over our heads during the Raptor Free Flight demonstration. I tried to get photos of it on the wing but it was too darned fast. Most impressive: however big they look in pictures, they look a heck of a lot bigger–and scarier–swooping two feet over your head.


Mexican Wolf, Canis lupus baileyi


And, okay, here’s a sauropod, or part of a sauropod: a mounted cast of the forelimb of Sonorasaurus thompsoni. Nine-year-old Homo sapiens for scale.

So, pretty outstanding place, and I highly recommend going. But, like every other printed or digital source I found, I recommend getting there first thing in the morning to see all the animals while they are out and about. London and I walked out of the big “critter loops” at 10:30 and the Mexican wolf was the only animal still roaming around.

Dödös need röck döts

Dodo skull drawing MJW 2013

It’s a strange time of year for me. Teaching and SVP are both behind me, my tenure dossier is in (I’ll find out how that goes next April, probably), and for the first time in a while, I’m not shepherding any pressing manuscripts through the valley of potential rejection. Urgency has dissipated. Flights of fancy are very in right now.

Take this post. I was supposed to be writing about intervertebral cartilage thickness in sauropods, but I got distracted and drew this instead. I am going through one of my periodic bouts of fascination with dodos, inspired by the awesome poster by Biedlingmaier et al. at SVP. So here’s an attempt. It’s based on this photo from Arkive:

Arkive Dodo-skull

with some details filled in from this plate from Strickland and Melville (1848):

Strickland and Melville dodo skull

and, to be honest, a very generous helping of artistic license. I don’t know from bird skulls so I may have the basioccipital wired to the nasals or some other godawful assault on sanity. I did it for fun, not for science.

If you want dodo science, I have mixed great news. Crappily–and futilely–enough, Owen’s descriptive papers on the dodo are paywalled at Transactions of the Zoological Society of London. (Seriously, guys? After 140 years you still haven’t made your nut off those papers?) BUT you can get them for free from a couple of other places–see Sarah Werning’s comment below. And happily Strickland and Melville (1848) is available for free from the Internet Archive, and in a host of formats. I am sorely tempted to have a hardcopy printed through Lulu. For more on the dodo side of the Aves 3D project underway at the Claessens lab, of which the Biedlingmaier et al. poster is early fruit, check out the news stories here, here, and here, and keep your fingers firmly crossed for the coming year. I can say no more for now.

If, like me, you are just a dodo fanperson, these videos with Adam Savage make interesting viewing: originalsequel.

Röck döts inspired by a few hours of stippling, and copied and pasted, appropriately, from False Machine.
