The last time we saw the sauropod femur that Paige Wiren discovered sticking out of a riverbank, it had been moved into the prep lab at the Moab Museum, with the idea that it would eventually go on exhibit as a touch specimen for the public to enjoy and be inspired by. That has come to pass.

I was in Moab last month with Drs. Jessie Atterholt and Thierra Nalley and we stopped in the Moab Museum to digitize some vertebrae from SUSA 515, an unusual specimen of Camarasaurus that I’ve blogged about before, and will definitely blog about again. While we were there, we got to see and touch the Wiren femur. The museum folks told us that femur has been the first dinosaur bone that a lot of schoolkids and tourists have seen up close, or gotten to touch. As a former dinosaur-obsessed kid who never stopped being excited about touching real dinosaur bones–and as one of the lucky folks that got to rescue this particular fossil from erosion or poaching–that pleases me deeply. 

So, obviously, you should go see this thing. And the rest of the museum–as you can see from the photos above, the whole place has been renovated, and there are lots of interesting fossils from central and eastern Utah on display, not to mention loads of historical artifacts, all nicely presented in a clean, open, well-lit space that invites exploration. Go have fun!

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? One part of the answer is that the value of a published paper to the commnity is higher still: were it not so, no-one would be paying. But that can’t be the whole reason.

In an efficient market, competing providers of a good will each try to undercut each other until the prices they charge approach the cost. If, for example, Elsevier and Springer-Nature were competing in a healthy free market, they would each be charging prices around one third of what they are charging now, for fear of being outcompeted by their lower-priced competitor. (Half of those price-cuts would be absorbed just by decreasing the huge profit margins; the rest would have to come from streamlining business processes, in particular things like the costs of maintaining paywalls and the means of passing through them.)

So why doesn’t the Invisible Hand operate on scholarly publishers? Because they are not really in competition. Subscriptions are not substitutable goods because each published article is unique. If I need to read an article in an Elsevier journal then it’s no good my buying a lower-priced Springer-Nature subscription instead: it won’t give me access to the article I need.

(This is one of the reasons why the APC-based model — despite its very real drawbacks — is better than the subscription model: because the editorial-and-publication services offered by Elsevier and Springer-Nature are substitutable. If one offers the service for $3000 and the other for $2000, I can go to the better-value provider. And if some other publisher offers it for $1000 or $500, I can go there instead.)

The last few years have seen huge and welcome strides towards establishing open access as the dominant mode of publication for scholarly works, and currently output is split more or less 50/50 between paywalled and open. We can expect OA to dominate increasingly in future years. In many respects, the battle for OA is won: we’ve not got to VE Day yet, but the D-Day Landings have been accomplished.

Yet big-publisher APCs still sit in the $3000–$5000 range instead of converging on $500-$1000. Why?

Björn Brembs has been writing for years about the fact that every market has a luxury segment: you can buy a perfectly functional wristwatch for $10, yet people spend thousands on high-end watches. He’s long been concerned that if scholarly publishing goes APC-only, then people will be queuing up to pay the €9,500 APC for Nature in what would become a straightforward pay-for-prestige deal. And he’s right: given the outstandingly stupid way we evaluate reseachers for jobs, promotion and tenure, lots of people will pay a 10x markup for the “I was published in Nature” badge even though Nature papers are an objectively bad way to communicate research.

But it feels like something stranger is happening here. It’s almost as though the whole darned market is a luxury segment. The average APC funded by the Wellcome Trust in 2018/19 was £2,410 — currently about $3,300. Which is almost exactly the average article cost of $3,333 that we calculated earlier. What’s happening is that the big publishers have landed on APCs at rates that preserve the previous level of income. That is understandable on their part, but what I want to know is why are we still paying them? Why are all Wellcome’s grantees not walking away from Elsevier and Springer-Nature, and publishing in much cheaper alternatives?

Why, in other words, are market forces not operating here?

I can think of three reasons why researchers prefer to spend $3000 instead of $1000:

  1. It could be that they are genuinely getting a three-times-better service from the big publishers. I mention this purely for completeness, as no evidence supports the hypothesis. There seems to be absolutely no correlation between price and quality of service.
  2. Researchers are coasting on sheer inertia, continuing to submit to the journals they used to submit to back in the bad old days of subscriptions. I am not entirely without sympathy for this: there is comfort in familiarity, and convenience in knowing a journal’s flavour, expectations and editorial board. But are those things worth a 200% markup?
  3. Researchers are buying prestige — or at least what they perceive as prestige. (In reality, I am not convinced that papers in non-exceptional Elsevier or Springer-Nature journals are at all thought of as more prestigous than those in cheaper but better born-OA journals. But for this to happen, it only needs people to think the old journals are more prestigious, it doesn’t need them to be right.)

But underlying all these reasons to go to a more expensive publishers is one very important reason not to bother going to a cheaper publisher: researchers are spending other people’s money. No wonder they don’t care about the extra few thousand pounds.

How can funders fix this, and get APCs down to levels that approximate publishing cost? I see at least three possibilities.

First, they could stop paying APCs for their grantees. Instead, they could add a fixed sum onto all grants they make — $1,500, say — and leave it up to the researchers whether to spend more on a legacy publisher (supplementing the $1,500 from other sources of their own) or to spend less on a cheaper born-OA publisher and redistribute the excess elsewhere.

Second, funders could simply publish the papes themselves. To be fair several big funders are doing this now, so we have Wellcome Open Research, Gates Open Research, etc. But doesn’t it seem a bit silly to silo research according to what body awarded the grant that funded it? And what about authors who don’t have a grant from one of these bodies, or indeed any grant at all?

That’s why I think the third solution is best. I would like to see funders stop paying APCs and stop building their own publishing solutions, and instead collaborate to build and maintain a global publishing solution that all researchers could use irrespective of grant-recipient status. I have much to say on what such a solution should look like, but that is for another time.

We have a tendency to be sloppy about language in everyday usage, so that words like “cost”, “value” and “price” are used more or less interchangeably. But economists will tell you that the words have distinct meanings, and picking them apart is crucial to understand economic transaction. Suppose I am a carpenter and I make chairs:

  • The cost of the chair is what it costs me to make it: raw materials, overheads, my own time, etc.
  • The value of the chair is what it’s worth to you: how much it adds to your lifestyle.
  • The price of the chair is how much you actually pay me for it.

In a functioning market, the value is more than the cost. Say it costs me £60 to make the chair, and it’s worth £100 to you. Then there is a £40 range in which the price could fall and we would both come out of the deal ahead. If you buy the chair for £75, then I have made £15 more than what it cost me to make, so I am happy; and you got it for £25 less than it was worth to you, so you’re happy, too.

(If the value is less than the cost, then there is no happy outcome. The best I can do is dump the product on the market at below cost, in the hope of making back at least some of my outlay.)

So far, so good.

Now let’s think about scientific publications.

There is a growing consensus that the cost of converting a scientific manuscript into a published paper — peer-reviewed, typeset, made machine-readable, references extracted, archived, indexed, sustainably hosted — is on the order of $500-$1000.

The value of a published paper to the world is incredibly hard to estimate, but let’s for now just say that it’s high. (We’ll see evidence of this in a moment.)

The price of a published paper is easier to calculate. According to the 2018 edition of the STM Report (which seems to be the most recent one available), “The annual revenues generated from English-language STM journal publishing are estimated at about $10 billion in 2017 […] collectively publishing over 3 million articles a year” (p5). So, bundling together subscription revenues, APCs, offsets deals and what have you, the average revenue accruing from a paper is $10,000,000,000/3,000,000 = $10,000/3 = $3,333.

(Given that these prices are paid, we can be confident that the value is at least as much, i.e. somewhere north of $3,333 — which is why I was happy earlier to characterise the value as “high”.)

Why is it possible for the price of a paper to be 3–7 times as high as its cost? One part of the answer is that the value is higher still. Were it not so, no-one would be paying. But that can’t be the whole reason.

Tune in next time to find out the exciting reason why the price of scholarly publishing is so much higher than the cost!

I have the honor of giving the National Fossil Day Virtual Lecture for The Museums of Western Colorado – Dinosaur Journey, next Wednesday, October 13, from 7:00 to 8:00 PM, Mountain Daylight Time. The title of my talk is “Lost Giants of the Jurassic” but it’s mostly going to be about Brachiosaurus. And since I have a whole hour to fill, I’m gonna kitchen-sink this sucker and put in all the good stuff, even more than last time. The talk is virtual (via Zoom) and free, and you can register at this link.

The photo up top is from this July. That’s John Foster (standing) and me (crouching) with the complete right humerus of Brachiosaurus that we got out of the ground in 2019; that story is here. The humerus is in the prep lab at the Utah Field House of Natural History State Park Museum in Vernal, and if you go there, you can peer through the tall glass windows between the museum’s central atrium and the prep lab and see it for yourself.

If you’ve forgotten what a humerus like that looks like in context, here’s the mounted Brachiosaurus skeleton at the North American Museum of Ancient Life with my research student, Kaelen Kay, for scale. Kaelen is 5’8″ (173cm) and as you can see, she can just get her hand on the animal’s elbow. The humerus–in this case, a cast of the right humerus from the Brachiosaurus altithorax holotype–is the next bone up the line. Kaelen came out with us this summer and helped dig up some more of our brachiosaur–more on that story in the near future.

Want more Brachiosaurus? Tune in next week. Here’s that registration link again. I hope to see you there!

On Thursday, I took the family to the Cotswolds Wildlife Park, a rather lovely zoo just over an hour away from us in Burford, Oxfordshire. Somehow I’d never even heard of this place until we passed a sign for it on the A417 a few weeks ago. Lots of great stuff there, but I wanted to focus on this:

As you can see, the clump of big trees in the giraffe enclosure has had all its foliage methodically stripped off, right up to the point where the tallest giraffe can reach, giving it a striking mushroom shape.

Two days ago, I wrote about what seemed to be an instance of peer review gone very wrong. I’ve now heard from two of the four authors of the paper and from the reviewer in question — both by email, and in comments on the original post — and it’s apparent that I misinterpreted the situation. When the lead author’s tweet mentioned “pushing it through eight rounds of review”, I took this at face value as meaning eight rounds at the same journal with the same reviewers — whereas in fact the reviewer in question reviewed only four drafts. (That still seems like too many to me, but clearly it’s not as ludicrous as the situation as I misread it.) In this light, my assumption that the reviewer was being obstructive was not warranted.

I have decided to retract that article and I offer my apologies to the reviewer, Dave Grossnickle, who approached me very politely off-list to offer the corrections that you can now read in his comment.

Today should be a day of rejoicing, as it brings us a new sauropod: Arackar licanantay Rubilar-Rogers et al. 2021., a small titanosaur from Chile.

It’s not, though. Because not only is this paper behind a paywall in Elsevier’s journal Cretaceous Research, but the paywalled paper is what they term a “pre-proof” — a fact advertised in a tiny font half way down the page rather than in a giant red letters at the top.

“Pre-proof” is not a term in common usage. What does it mean? It turns out to be an unformatted, double-spaced, and line-numbered manuscript. In other words, this is an AAM (author’s accepted manuscript) of the kind that the authors could have deposited in their institutional repository for anyone to read for free.

But wait — there’s more! By way of “added value”, Elsevier have slapped a big intrusive “journal pre-proof” watermark across the middle of every single page, to make it even less readable than a double-spaced line-numbered manuscript already is:

Sample page from “pre-proof” of Rubilar-Rogers et al. 2021. Reproduced under the Fair Dealing doctrine as non-commercial research, criticism / review / quotation, and news reporting (sections 29, 30, 178 of the Copyright, Designs and Patents Act 1988). Get back in your box, Elsevier copyright lawyers.

If you want to see this for yourself, Elsevier will let you download it for $37.95:

Yeah. Thirty-seven dollars and 95 cents.

And now, the punchline. You may be wondering why, when a new sauropod has been announced, I didn’t lead with a nice image of one of the vertebrae? After all, are we not Sauropod Vertebra Picture of the Week?

It’s because there are no images of the vertebra. There are no images of any of the fossil material. In fact, there are no images at all.

Yes. This “pre-proof” omits all twelve illustrations. (We know there are twelve images, because all the figure captions appear at the end.) I have no idea what Arackar licanantay looks like. None at all. And for this, let’s just remind ourselves again, they charge $37.95.

I want to be careful throwing words like “fraud” around, but what I will say is that this is behaviour unbecoming of a major and once-respected multinational corporation. If a publisher’s behaviour ever merited the label “predatory”, surely this is it.

Have you been reading Justin Tweet’s series, “Your Friends the Titanosaurs“, at his awesomely-named blog, Equatorial Minnesota? If not, get on it. He’s been running the series since June, 2018, so this notice is only somewhat grotesquely overdue. The latest installment, on Alamosaurus from Texas and Mexico, is phenomenal. I have never seen another summary or review that pulled together so much of the relevant literature and explained it all so well. Seriously, that blog post deserves to be a review paper; it could be submitted pretty much as-is, although it would be even better with his two other Alamosaurus posts integrated (this one, and this one). It’s great work, is what I’m saying, and it needs to be acknowledged.

In particular, I was struck by the note by Anonymous in 1941 on the discovery of a cervical vertebra 1.2 meters long. I’d never heard of that ref, and I’ve never seen that vert, but at 120cm it would be in the top 7 longest cervical vertebrae on the planet (see the latest version of the list in this post), narrowly beating out the 118-cm cervical of Puertasaurus. In fairness, the preserved cervical of Puertasaurus is probably a posterior one, and more anterior cervicals might have been longer. Then again, in the big Alamosaurus neck the longest verts are pretty darned posterior, so…we need more Puertasaurus.

EDIT a few hours later: Thanks to the kind offices of Justin Tweet, I’ve now seen Anonymous (1941), and the exact wording is, “A single vertebra, or neck joint bone, is three feet across, only two inches less than four feet long, and in its present fossilized state weighs 600 pounds.” ‘Two inches less than four feet long’ is 46 inches or a hair under 117cm, which puts the supposed giant cervical just behind Puertasaurus after all, but still firmly in the top 10. And depending on how one interprets the passage in Anonymous (1941), it might not have been any bigger than BIBE 45854–see this comment for details.

Big cervical showdown. From the top left: BYU 9024, originally referred to Supersaurus but more likely representing a giant Barosaurus (137cm); the single available cervical of Puertasaurus (118cm); a world-record giraffe neck (2.4m); Alamosaurus referred cervical series BIBE 45854, longest centra are ~81cm; Sauroposeidon holotype OMNH 53062, longest centrum is 125cm. This image makes it very clear that whatever Sauroposeidon was doing, it was a way different thing from Alamosaurus.

Crucially, the longest vertebrae in the BIBE 45854 series are about 80 or 81 cm long, which means that a 1.2-meter cervical would be half again as large. That is a pretty staggering thought, and that individual of Alamosaurus–assuming it was the same taxon as BIBE 45854, and not some other, longer-necked critter–would definitely be a contender for the largest sauropod of all time.

Illustrations here are of the big Alamosaurus cervical series from Big Bend, which was comprehensively described by Ron Tykoski and Tony Fiorillo in 2016, and which we have covered in these previous posts:

Today marks the one-month anniversary of my and Matt’s paper in Qeios about why vertebral pneumaticity in sauropods is so variable. (Taylor and Wedel 2021). We were intrigued to publish on this new platform that supports post-publication peer-review, partly just to see what happened.

Taylor and Wedel (2021: figure 3). Brontosaurus excelsus holotype YPM 1980, caudal vertebrae 7 and 8 in right lateral view. Caudal 7, like most of the sequence, has a single vascular foramen on the right side of its centrum, but caudal 8 has two; others, including caudal 1, have none.

So what has happened? Well, as I write this, the paper has been viewed 842 times, downloaded a healthy 739 times, and acquired an altmetric score 21, based rather incestuously on two SV-POW! blog-posts, 14 tweets and a single Mendeley reader.

What hasn’t happened is even a single comment on the paper. Nothing that could be remotely construed as a post-publication peer-review. And therefore no progress towards our being able to count this as a peer-reviewed publication rather than a preprint — which is how I am currently classifying it in my publications list.

This, despite our having actively solicited reviews both here on SV-POW!, in the original blog-post, and in a Facebook post by Matt. (Ironically, the former got seven comments and the latter got 20, but the actual paper none.)

I’m not here to complain; I’m here to try to understand.

On one level, of course, this is easy to understand: writing a more-than-trivial comment on a scholarly article is work, and it garners very little of the kind of credit academics care about. Reputation on the Qeios site is nice, in a that-and-two-bucks-will-buy-me-a-coffee kind of way, but it’s not going to make a difference to people’s CVs when they apply for jobs and grants — not even in the way that “Reviewed for JVP” might. I completely understand why already overworked researchers don’t elect to invest a significant chunk of time in voluntarily writing a reasoned critique of someone else’s work when they could be putting that time into their own projects. It’s why so very few PLOS articles have comments.

On the other hand, isn’t this what we always do when we write a solicited peer-review for a regular journal?

So as I grope my way through this half-understood brave new world that we’re creating together, I am starting to come to the conclusion that — with some delightful exceptions — peer-review is generally only going to happen when it’s explicitly solicited by a handling editor, or someone with an analogous role. No-one’s to blame for this: it’s just reality that people need a degree of moral coercion to devote that kind of effort to other people’s project. (I’m the same; I’ve left almost no comments on PLOS articles.)

Am I right? Am I unduly pessimistic? Is there some other reason why this paper is not attracting comments when the Barosaurus preprint did? Teach me.



Can I really be the first one to have done this? Seems unlikely. Sing out in the comments if you’ve seen others.

Anyway, folks, here’s your new all-purpose scale silhouette. Useful fact: the standard metal folding chairs found from sea to shining sea are 29.25 inches tall, or 0.75 meters. Bernie might be in a plastic folding chair here, I dunno, I’m no expert. But folding chair seats are typically 16-17 inches off the ground, so it can’t be that far out.

Who will get Bernie into print first?
