TL;DR: if you know where I can get a notebook just like this one, or from the same manufacturer and made to the same specs, or have one of your own that I could buy off you (provided it’s mostly unused), please let me know in the comments.
This is the best notebook I’ve ever used. The cover is 7.25 x 10 inches, made of some kind of dense and probably recycled paper board. It’s twin-loop wire bound, has a button-and-string closure and a separate loop of board inside the back cover to hold a pen or pencil. Heavyweight cream paper. Has a fossil fish, Eoholocentrum macrocephalum, embossed on the cover, with the Linnean binomial properly capitalized and italicized.
I’ve used loads of other notebooks, including several sizes and designs of Moleskine and Rite-in-the-Rain, and this one is by far my favorite. Why? It lies flat when open or folded back on itself, the wire binding has never hung up, torn a page, or otherwise malfunctioned in over four years of travel and heavy use, and the pen holder and button string closure are perfect for my purposes. I’ve never had a notebook with an elastic band that didn’t wear out, and I usually have to build my own pen loops out of tape.
The one I have was a gift from Mark Hallett, who picked it up at SVP some years ago. Neither of us know who made it. But I’d really like to have another one, because mine is almost full. So far all of my searching online and off has failed to turn up a notebook like this, either another original or one with the same features made to the same specs. So if you know something about this, please pass it on!

I’m back in Oklahoma for the holidays, and anytime I’m near Norman I pop in to the OMNH to see old friends, both living and fossil. Here’s the Aquilops display in the hall of ancient life, which has been up for a while now. I got some pictures of it when I was here back in March, just never got around to posting them.
Aquilops close up. You can’t see it well in this pic, but on the upper right is a cast of the Aquilops cranium with a prosthesis that shows what the missing bits would have looked like. That prosthesis was sculpted by – who else? – Kyle Davies, the OMNH head preparator and general sculpting/molding/casting sorceror. You’ve seen his work on the baby apatosaur in this post. I have casts of everything shown here – original fossil, fossil-plus-prosthesis, and reconstructed 3D skull – and I should post on them. Something to do in the new year.
The Aquilops display is set just opposite the Antlers Formation exhibit, which has a family of Tenontosaurus being menaced by two Deinonychus, and at the transition between Early and Late Cretaceous. The one mount in the Late Cretaceous area is the big Pentaceratops, which is one of the best things in this or any museum.
Evidence in support of that assertion. Standing directly in front of this monster is a breathtaking experience, which I highly recommend to everyone.
It’s just perfect that you can see the smallest and earliest (at least for now) North American ceratopsian adjacent to one of the largest and latest. Evolution, baby!
I didn’t only look at dinosaurs – the life-size bronze mammoth in the south rotunda is always worth a visit, especially in holiday regalia.
No holiday post about the OMNH would be complete without a shot of “Santaposeidon” (previously seen here). I will never get tired of this!
The chances that I’ll get anything else posted in 2016 hover near zero, so I hope you all have a safe and happy holiday season and a wonderful New Year.

In the summer of 2015, Brian Engh and I stopped at the Copper Ridge dinosaur trackway on our way back from the field. The Copper Ridge site is 23 miles north of Moab, off US Highway 191. You can find a map, directions, and some basic information about the site in this brochure. The BLM has done a great job of making this and other Moab-area dinosaur trackways accessible to the public, with well-tended trails and nice interpretive signage. Brian has gotten to do the art for interp signs at several sites now, including Copper Ridge, and he put together this video to explain a bit about the site, what we know about the trackmaker, and the lines of evidence he used in making his life restoration. I’m in there, too, yammering a bit about which sauropod might have been responsible. We weren’t sure what, if anything, we would end up doing with the footage at the time, so I’m basically thinking out loud. But that’s mostly what I do here anyway, so I reckon you’ll live.
Stay tuned (to Brian’s paleoart channel) for Part 2, which will be about the Copper Ridge theropod trackway. And the next time you’re in the Moab area, go see some dinosaur tracks. This is our heritage, and it’s cool.

Judgmental readers will recall that I have dabbled in mammal skulls, thanks to the corrupting influence of my friend and colleague, Brian Kraatz. At the end of my last post on this sordid topic, I mentioned that Brian and Emma Sherratt were working on a version 2.0 based in 3D morphometrics. The first volley from that project was published today in PeerJ.
Happily for all of us, Brian and Em confirmed the relationship between facial tilt and locomotor mode that we first documented last year, using more taxa, more landmarks, and two more dimensions (Kraatz and Sherratt 2016: 12):
…in accordance with previous findings by Kraatz et al. (2015), facial tilt angle is correlated with locomotor mode (D-PGLS, F(2,17) = 11.13, P = 0.003), where lower facial tilt angle, meaning more pronounced cranial flexion, is found in cursorial species, and high angles are found in generalist species.
That’s just the most personally relevant tip of a very large, multifaceted iceberg, including a monster supplementary info package on FigShare with, among other things, 3D models of bunny skulls. It’s all free and awesome, so go have fun.

I have before me the reviews for a submission of mine, and the handling editor has provided an additional stipulation:
Authority and date should be provided for each species-level taxon at first mention. Please ensure that the nominal authority is also included in the reference list.
In other words, the first time I mention Diplodocus, I should say “Diplodocus Marsh 1878″; and I should add the corresponding reference to my bibliography.
What do we think about this?
I used to do this religiously in my early papers, just because it was the done thing. But then I started to think about it. To my mind, it used to make a certain amount of sense 30 years ago. But surely in 2016, if anyone wants to know about the taxonomic history of Diplodocus, they’re going to go straight to Wikipedia?
I’m also not sure what the value is in providing the minimal taxonomic-authority information rather then, say, morphological information. Anyone who wants to know what Diplodocus is would be much better to go to Hatcher 1901, so wouldn’t we serve readers better if we referred to “Diplodocus (Hatcher 1901)”
Now that I come to think of it, I included “Giving the taxonomic authority after first use of each formal name” in my list of
Idiot things that we we do in our papers out of sheer habit three and a half years ago.
Should I just shrug and do this pointless busywork to satisfy the handling editor? Or should I simply refuse to waste my time adding information that will be of no use to anyone?

As explained in careful detail over at Stupid Patent of the Month, Elsevier has applied for, and been granted, a patent for online peer-review. The special sauce that persuaded the US Patent Office that this is a new invention is cascading peer review — an idea so obvious and so well-established that even The Scholarly Kitchen was writing about it as a commonplace in 2010.
Well. What can this mean?
A cynic might think that this is the first step an untrustworthy company would take preparatory to filing a lot of time-wasting and resource-sapping nuisance lawsuits on its smaller, faster-moving competitors. They certainly have previous in the courts: remember that they have brought legal action their own customers as well as threatening Academia.edu and of course trying to take Sci-Hub down.
Elsevier representatives are talking this down: Tom Reller has tweeted “There is no need for concern regarding the patent. It’s simply meant to protect our own proprietary waterfall system from being copied” — which would be fine, had their proprietary waterfall system not been itself copied from the ample prior art. Similarly, Alicia Wise has said on a public mailing list “People appear to be suggesting that we patented online peer review in an attempt to own it. No, we just patented our own novel systems.” Well. Let’s hope.
But Cathy Wojewodzki, on the same list, asked the key question:
I guess our real question is Why did you patent this? What is it you hope to market or control?
We await a meaningful answer.
Just posting a few images from my impending talk at SVPCA this Thursday.
I’ve written about the recurrent laryngeal nerve before, in Wedel (2012) and in this post. It’s present in all tetrapods, from frogs and salamanders on up. The frog RLN is shown in ventral view above, and in lateral view below, both from Ecker (1889:plate 1, figures 114 and 115). I’ve highlighted the RLN in red in both. Perhaps not a monument of inefficiency, but still recurrent, and therefore dumb.
And in a giraffe – RLN in blue, nerve path to hindfoot phalanges in red. Hollow circles are nerve cell bodies, solid lines are axons.
And in the elasmosaur Hydrotherosaurus, same color scheme plus the nerve path to the tail in purple, base image from Welles (1943).
That’s all for now!
