I got an email this morning from Jim Kirkland, announcing:

All of the lectures (with permission to be filmed) will be available on the NHMU YouTube channel. I just wrapped the edit of the 6th video which should be available later today. However, 5 of the lectures are now edited and already available for viewing. They can be found here.

And by the time I read that message, the sixth talk had appeared!

Each talk is 20-25 minutes long, so there’s a good two and a quarter hours of solid but accessible science here, freely available to anyone who wants to watch them. Here, to get you started, is long-time friend of SV-POW!, Randy Irmis, on Discovering Dinosaur Origins in Utah:

It’s great that the DinoFest people are doing this. In 2017, it should really be the default — and yet I can’t think of a single vertebrate palaeo conference that has done this before. (Did I miss some? Links, please!)

I know it’s one more thing for conference organisers to have to think about (or, more optimistically, one more thing for them to delegate). but I hope we’ll be seeing a lot more of it!

Help me find this notebook

January 30, 2017

best-notebook-ever

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.

best-notebook-ever-2

Long version:

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!

It’s now been widely discussed that Jeffrey Beall’s list of predatory and questionable open-access publishers — Beall’s List for short — has suddenly and abruptly gone away. No-one really knows why, but there are rumblings that he has been hit with a legal threat that he doesn’t want to defend.

To get this out of the way: it’s always a bad thing when legal threats make information quietly disappear; to that extent, at least, Beall has my sympathy.

That said — over all, I think making Beall’s List was probably not a good thing to do in the first place, being an essentially negative approach, as opposed to DOAJ’s more constructive whitelisting approach. But under Beall’s sole stewardship it was a disaster, due to his well-known ideological opposition to all open access. So I think it’s a net win that the list is gone.

But, more than that, I would prefer that it not be replaced.

Researchers need to learn the very very basic research skills required to tell a real journal from a fake one. Giving them a blacklist or a whitelist only conceals the real issue, which is that you need those skills if you’re going to be a researcher.

Finally, and I’m sorry if this is harsh, I have very little sympathy with anyone who is caught by a predatory journal. Why would you be so stupid? How can you expect to have a future as a researcher if your critical thinking skills are that lame? Think Check Submit is all the guidance that anyone needs; and frankly much more than people really need.

Here is the only thing you need to know, in order to avoid predatory journals, whether open-access or subscription-based: if you are not already familiar with a journal — because it’s published research you respect, or colleagues who you respect have published in it or are on the editorial board — then do not submit your work to that journal.

It really is that simple.

So what should we do now Beall’s List has gone? Nothing. Don’t replace it. Just teach researchers how to do research. (And supervisors who are not doing that already are not doing their jobs.)

 

Back in February last year, I had the privilege of giving one of the talks in the University of Manchester’s PGCert course “Open Knowledge in Higher Education“. I took the subject “Should science always be open?”

My plan was to give an extended version of a talk I’d given previously at ESOF 2014. But the sessions before mine raised all sorts of issues about copyright, and its effect on scholarly communication and the progress of science, and so I found myself veering off piste. The first eight and a half minutes are as planned; from there, I go off on an extended tangent. Well. See what you think.

The money quote (starting at 12m10s): “What is copyright? It’s a machine for preventing the creation of wealth.”

Welcome to 2017! Let’s start the year with a cautionary tale. I’ll leap straight to the moral, then give an example: it’s very easy to reach the wrong conclusion about fossils from photos. That’s because no single photo can give an accurate impression of distortion. For that, you need at least a much bigger selection of photos; or better still, a 3d model; or of course best of all, the fossil itself.

Here’s the motivating example:

unnamed

Cervical vertebrae 8-16 of Barosaurus lentus AMNH 6341; and BYU 9024 “Supersaurus” cervical ?9. All in left lateral view.

A correspondent — I will not divulge his or her name unless the person in question chooses to reveal it — had looked over the slides for our 2016 SVPCA talk on new Barosaurus specimens, which claims that Jensen’s Dry Mesa “Supersaurus” cervical BYU 9024 actually belongs to Barosaurus.

Matt and I felt, based largely on the degree of neural spine bifurcation, that the BYU vertebra compares most similarly to C9 of the AMNH specimen — the middle one in the top row of the composite illustration above. But my correspondent put together the composite, and wrote [lightly edited for clarity]:

I’ve already compared BYU 9024 with the AMNH cervicals, I attach a photo, because for me it is also very similar to C14: the centrum is much more similar to C14 than C9, I think. What do you think about this?

Like I said: you always need to be careful about interpreting any one view of a fossil. In this case, BYU 9024 is misleading in lateral view because the CPOLs are folded upwards and inwards, and the ventrolateral flanges are (to a lesser extent) folded downwards and inwards — making the posterior part of the centrum look much taller (and rather narrower) than it really is.

This is hard to see in photos, because the fossil is so smashed up and the matrix is so visually similar to the bone, but take a look at the posterior view (with anterior to the right of the photo):

img_3516

Here are the key parts, annotated, as best I can make out. (And bear in mind that even I am not sure, after having spent a whole day with the fossil, and with literally hundreds of photos to consult.)

img_3516-annotated

As you can see, the centrum accounts for only a small proportion of the apparent height of the posterior end of the vertebra — and even that is probably exaggerated, as the eccentricity of the condyle indicates that crushing has increased its height at the expense of its width.

Put it all together, and Jensen’s much-derided sculpture of what the vertebra should have looked like is actually pretty good:

img_3399

The upshot of this anecdote is an obvious one, but it bears repeating: you simply cannot do a meaningful description of a fossil without seeing it yourself — or at the very least a high-quality 3d model. Photos just won’t cut it.

aquilops-display-omnh-dec-2016-1

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-omnh-dec-2016-2

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.

ceratopsians-large-and-small-omnh-dec-2016-3

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.

pentaceratops-omnh-dec-2016-4

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!

mammoth-santa-omnh-dec-2016-5

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.

santaposeidon-omnh-dec-2016-6

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.
