Little, big: the reveal

University of Bristol

Suppose you’re working on a Wealden sauropod — for example, the disturbingly

 Camarasaurus

-like isolated dorsal vertebra NHM R2523 — and for some reason you desperately want to publish your work in

 Cretaceous Research

. {.aligncenter .size-full .wp-image-8841 loading=“lazy” attachment-id=“8841” permalink=“http://svpow.com/2013/09/14/who-owns-journals/bmnh-r2523-orthogonal/”

Who owns journals?

I have discovered a new nugget of information in my ongoing quest (part 1, part 2, part 3) to discover what the licence terms are for author-pays Gold Open Access articles in Elsevier journals. You will recall from way back in part 1 that Elsevier’s own “Sponsored Articles” page doesn’t include that information. A while after I posted that, they added a link to this page.

Understanding Elsevier’s open-access licence, part 4: who owns copyright?

I was searching for some information — what proportion of Elsevier’s revenue is from journal subscriptions.  So far, I’ve been unsuccessful with that (can anyone help?), but along the way I stumbled across Elsevier’s Annual Reports and Financial Statements for 2011. And it makes happy reading.

It’s not all doom and gloom in academia: at least Elsevier are increasing their profits!

Friday evening I was in a pub with Mike, Darren, John Conway, and Emma Lawlor. We were killing time waiting for the Pink Giraffe Chinese restaurant down the street to open. I was chatting with John about “All Todays”, his speculative presentation with Cevdet Kosemen (a.k.a. Nemo Ramjet) on how future sentients might reconstruct Holocene animals if they were known only from fossils.

I recently handled the revisions on a paper that hopefully will be in press very soon. One of the review comments was “Be very careful not to make

 ad hominem

attacks”. I was a bit surprised to see that — I wasn’t aware that I’d made any — so I went back over the manuscript, and sure enough, there were no

 ad hom

s in there. There was criticism, though, and I think that’s what the reviewer meant.

What is an ad-hominem attack?

A short one, because I’ve been commenting on other people’s blogs a lot recently (

 Scholarly Kitchen

,

 Open and Shut

,

 The Scientist

) and it infuriates me how hard it is get a good back-and-forth discussion going in those venues. The contrast of course is with SV-POW!

Tutorial 18: how to have fruitful discussions in your blog’s comments

Remember at the start of the year, Matt and I had a contest to design a cover for a random book in half an hour?

Hey! They stole my book cover!

I was recently bemoaning the lack of published diplodocid cervical illustrations in dorsal view. Subsequently I mentioned that Upchurch et al. (2005) had illustrated five cervicals of an

 Apatosaurus

specimen. I was overlooking one other paper that contains such an illustration. Which is a bit embarrassing, as it’s one of ours. In fact, it’s our most recent paper, Wedel and Taylor (2013) on sauropod neural spine bifurcation.

As the conference season heaves into view again, I thought it was worth gathering all four parts of the old Tutorial 16 (“giving good talks”) into one place, so it’s easy to link to. So here they are:

 Part 1: Planning: finding a narrative

Make us care about your project. Tell us a story. You won’t be able to talk about everything you’ve done this year. Omit much that is relevant. Pick a single narrative. Ruthlessly prune.

Despite the flagrant trolling of its title,

 Nature

’s recent opinion-piece Open access is tiring out peer reviewers is mostly pretty good. But the implication that the rise of open-access journals has increased the aggregate burden of peer-review is flatly wrong, so I felt obliged to leave a comment explaining why. Here is that comment, promoted to a post of its own (with minor edits for clarity):

Open-access megajournals reduce the peer-review burden

Long time readers may remember the stupid contortions I had to go through in order to avoid giving the Geological Society copyright in my 2010 paper about the history of sauropod research, and how the Geol. Soc. nevertheless included a fraudulent claim of copyright ownership in the published version. The way I left it back in 2010, my wife, Fiona, was the copyright holder.

I first met Wann at SVP in 1997, in Chicago. I was an undergrad, still three months away from my B.S., presenting a poster arguing that OMNH 53062 (which would eventually become the holotype of

 Sauroposeidon

) was a new sauropod.

It’s pretty amazing to realise we’ve been running SV-POW! for nearly seventeen years now, since 1st October 2007. And it’s astonishing, and gratifying, and even a tiny by humbling, to see how popular it’s been in its niche. That niche has turned out to be a bit bigger than we could have imagined, and I am delighted to say that earlier today we notched up our five millionth view!

Five million hits!

As promised, some thoughts on the various new brachiosaur mass estimates in recent papers and blog-posts. Back in 2008, when I did the GDI of

 Giraffatitan

and

 Brachiosaurus

for my 2009 paper on those genera, I came out with estimates of 28688 and 23337 kg respectively. At the time I said to Matt that I was suspicious of those numbers because they seemed too low.

How much is our intuition about sauropod mass worth?

(First of all, for anyone who’s not familiar with the plural of “pubis”, it’s spelled “pubes” but pronounced “pyoo-bees”. Stop sniggering at the back.) As Matt and I struggle to figure out the partial pubis that is one of the elements of the “

 Apatosaurus

”

 minimus

specimen AMNH 675, one of the most helpful references is Osborn and Mook’s (1921) epic monograph on

 Camarasaurus

. It’s not that 675 particularly resembles

Camarasaurus pubes of the AMNH

I am co-authoring a manuscript that, among other things, tries to trace the history of the molds made by the Carnegie Museum in the early 1900s, from which they cast numerous replica skeletons of the

 Diplodocus carnegii

mount (CM 84, CM 94, CM 307 and other contributing specimens). This turns out to be quite a mystery, and I have become fascinated by it. Below is the relevant section of the manuscript as it now stands.

Help SV-POW!: what happened to the original Carnegie Diplodocus molds?

Matt and I are writing a paper about

 Barosaurus

cervicals (yes, again). Regular readers will recall that the best

 Barosaurus

cervical material we have ever seen was in a prep lab for Western Paleo Labs.

Seriously, though, what are we going to do about privately held specimens?

Naturally I was grateful when Cary invited me to be part of the team working on Dolly, the diplodocid with lesions in its neck vertebrae (Woodruff et al. 2022; see previous posts on Dolly here and here). I was also intellectually excited, not only to see air-filled bones with obvious pathologies, but also for what those pathologies could tell us about Dolly and other sauropods. That’s the part of our new paper I want to unpack in this post.

Sauro-throat, Part 3: what does Dolly’s disease tell us about sauropods?

We live in stupid times. As I write this, Google Scholar’s front page is advertising “New! AI outlines in Scholar PDF Reader: skim per-section bullets, deep read what you need”. Yes: it’s using AI to provide a short summary of what’s in a paper. Wouldn’t it be great if instead of a profoundly fallible AI summary, we could read a summary written by the actual authors, who know the material inside out? We can, of course.

Tutorial 46: how to write an abstract

I was at the SVP meeting in Albuquerque in 2018 when Cary Woodruff called me over and said he had something cool to show me. “Something cool” turned out to be photos of infected sauropod vertebrae from the Morrison Formation of Montana. Specifically, some gross, cauliflower-looking bony lesions bubbling up in the air spaces on the sides of the vertebrae.

Here at SV-POW!, we are an equal-opportunity criticiser of publishers: Springer, PLOS, Elsevier, the Royal Society, Nature, we don’t care. We call problems as we see them, where we see them. Here is one that has lingered for far too long.

Dear PLOS ONE: time to sort out your multiple review tracks

This is super cool: my friend and lead author on the new saltasaur pneumaticity paper, Tito Aureliano, made a short (~6 min) video about the fieldwork that Aline Ghilardi and Marcelo Fernandes and their team — many of whom are authors on the new paper — have been doing in Brazil, and how it led to the discovery of a new, tiny titanosaur, and how that led to the new paper. It’s in Portuguese, but with English subtitles, just hit the CC button.

Background Today has seen the release of a Bernstein Research investment report by Claudio Aspesi, entitled

It contains some stark warnings to potential investors: And: And most importantly, this conclusion: I’m not here to gloat.

How Elsevier can save itself, part 0: Introduction

A quick note to remind everyone that although the RWA is dead, that only brings us back to the status quo.  At present, it’s still the case that

 the great majority of US government-funded research goes behind paywalls

.  Although the National Institutes of Health (NIH) has a public access policy that is resulting in a lot of papers being posted for general access at PubMed Central, the NIH is only one of a dozen U.S.

Wouldn’t it be great if, after a meeting like the 2015 SVPCA, there was a published set of proceedings? A special issue of a journal, perhaps, that collected papers that emerge from the work presented there. Of course the problem with special issues, and edited volumes in general, is that they take

 forever

to come out.

A “special issue” for SVPCA 2015 proceedings

I am just back from SVPCA, where I saw fifty 20-minute talks in three days. (I try to avoid missing any talks at all if I can avoid it, and this year I did.) As always, there was lots of fascinating stuff, and much of it not about the topics that I would necessarily have expected to enjoy.

Give a talk that holds attention!

Mysterious, never-yet-outed titanosaur caudals

For a paper that I and Matt are preparing, we needed to measure the centrum length of a bunch of turkey cervicals. That turns out to be harder than you’d think, because of the curious negative curvature of the articular surfaces.

I just read Mark Witton’s piece on the new new titanosaur

 Rukwatitan

(as opposed to the old new titanosaur

 Dreadnoughtus

). I was going to write something about it, but I realised that Mark has already said everything I would have, but better. So get yourselves over to his piece and enjoy the titanosaurianness of it all!

Please welcome Rukwatitan (over on Mark Witton’s blog)

Last time, we looked at the difference between cost, value and price, and applied those concepts to simple markets like the one for chairs, and the complex market that is scholarly publication. We finished with the observation that the price our community pays for the publication of a paper (about $3,333 on average) is about 3–7 times as much as its costs to publish ($500-$1000)?  How is this possible?

Why the price of scholarly publishing is so much higher than the cost

Back in 2013, John Conway was doing some paintings and Darren Naish was drawing lots of animals for a book. I chipped in to help with their artwork and some back and forth ensued. All this happened on Twitter, and I wrote it up in an SV-POW! post with lots of embedded tweets.  But with the progressing enshittification of Twitter (I refuse to call it X), that post is rendering less and less well, and at some point will probably fail completely.

While I was thinking about

atlas ribs, I was reminded of the ribs on the atlas of a diplodocine skull-and-three-cervicals exhibit that Matt and I saw at MOAL(*) back in the heady days of the Sauropocalypse. And that reminded me that I have other pairs of photos from the MOAL visit, which I took with the intention of making anaglyphs. like the one I did of the diplodocine.

The TL;DR is first that it’s offered at stupidly high prices, and secondly that it’s completely impossible to detect or prevent double-dipping because journal subscriptions are the most opaquely priced good in the known universe.

Funders have all the power in OA negotiations. So why aren’t they using it?

It’s been a minute, hasn’t it?  {.size-large .wp-image-18254 .aligncenter loading=“lazy” attachment-id=“18254” permalink=“http://svpow.com/2021/01/15/hey-look-sauropod-vertebrae/cm-diplo-and-apato-compared/” orig-file=“https://svpow.files.wordpress.com/2021/01/cm-diplo-and-apato-compared.jpg” orig-size=“1800,2103” comments-opened=“1”

Hey, look, sauropod vertebrae!

A couple of months ago, I asked for your help in compiling a list of all known complete sauropods necks. This has gone really well, and I want to thank everyone who chipped in, and all the various authors I have contacted for details as a result.

Yesterday I told you all about the Researcher to Reader (R2R) conference and its debate on the proposition “The venue of its publication tells us nothing useful about the quality of a paper”. I posted the opening statement

 for

the proposition, which was co-written by Toby Green and me. Now here is the opening statement

 against

the proposition, presented by Pippa Smart of

 Learned Publishing

, having been co-written by

Because I’ve worked a lot on the anatomy and evolution of air-filled bones in sauropod dinosaurs, I’ve spent most of my career looking at images like this:  {.wp-image-17072 .size-large aria-describedby=“caption-attachment-17072” loading=“lazy” attachment-id=“17072” permalink=“http://svpow.com/2020/01/28/natures-ct-machine/apatosaurus-cervical-ct-wedel-2003b-fig-5/”

It warmed my crooked little heart to see Mike Taylor, noted sauropodologist and disdainer-of-mammal-heads, return mammal skulls to the blog’s front page yesterday. Naturally I had to support my friend and colleague in this difficult time, when he may be experiencing confusing feelings regarding nasal turbinates, multi-cusped teeth, and the dentary-squamosal jaw joint.

Skull audit: Wedel responds

First, a short personal backstory. Vicki’s and my extended families both live mostly in Oklahoma and Kansas, so they only get to see our son, London, at the holidays or at infrequent mid-year visits. Starting when London was five, every year I’ve made a photo book of his adventures through the year to give as Christmas presents to all of our relatives. These have also become cherished mementos for the three of us here in Cali.

Pro tip: turn your talks into photo books

I’ve been on vacation for a couple of weeks, hence the radio silence here at SV-POW! after the flood of

 Supersaurus

posts and Matt’s new paper on aberrant nerves in human legs. But the world has not stood still in my absence (how rude of it!) and one of the more significant things to have happened in this time is the announcement of RVHost, a hosted end-to-end scholarly publishing solution provided by River Valley Technologies.

There are more and more options for non-exploitative publishers

The history of Supersaurus — and its buddies Ultrasauros and Dystylosaurus — is pretty complicated, and there seems to be no one source for it. But having read a lot about these animals in the process of writing eleven mostly pretty substantial posts about them, I feel like I’m starting to put it all together.

I belatedly realized that I caused some confusion in the original version of this post.

What’s up with your irregular ventral ridges, diplodocines?

Last time, I told you about my new paper, The Concrete

 Diplodocus

of Vernal (Taylor et al. 2023), and finished up by saying this: “But Mike, you ask — how did you, a scientist, find yourself writing a history paper? It’s a good question, and one with a complicated answer. Tune in next time to find out!” Paper 1 The truth is, I never set out to write a history paper. My goal was

If you followed along with the last post in this series, you now have some bird vertebrae to play with. Here are some things to do with them. 1. Learn the parts of the vertebrae, and compare them with those of other animals   Why are we so excited about bird vertebrae around here?

I wasted some time today making memes. I blame the Paleontology Coproliteposting group on Facebook.

Coproliteposting time!

The afternoon of Day 1 at TetZooCon 2018 was split into two parallel streams: downstairs, some talks that I would have

 loved

to see; and upstairs, a palaeoart workshop that I was even keener not to miss out on. There were talks by Luis Rey (on how palaeoart has had to be dragged kicking and screaming into accepting feathers and bright colours) and by Mark Witton (on the future of palaeoart — sadly, bereft of slides). Both fascinating.

Here’s the story of my fascination with supramedullary airways over the last 20 years, and how Jessie Atterholt and I ended up working on them together, culminating with her talk at SVPCA last week. (Just here for the preprint link?

Peer Review #3 of "Xenoposeidon is the earliest known rebbachisaurid sauropod dinosaur (v0.2)"

I was lucky enough to have Phil Mannion as one of the peer-reviewers for my recent paper (Taylor 2018) showing that

 Xenoposeidon

is a rebbachisaurid. During that process, we got into a collegial disagreement about one of the autapomorphies that I proposed in the revised diagnosis: “Neural arch slopes anteriorly 30°–35° relative to the vertical”. (This same character was also in the original

What does it mean for a vertebra to be “horizontal”?

Mark Witton says this better than I could: Like many white folks, I have traditionally assumed that simply not being racist was doing my part, and that the actions of others would eventually convert society at large to seeing race as the non-issue it should be. I have also felt that, as a white, straight […]

Mark Witton says this better than I could:  Go and read his post. I endorse it.  And remember: the opposite of Black Lives Matter is not All Lives Matter; it’s Black Lives Don’t Matter. Don’t be That Guy.
