More thoughts on SVPCA 2017

October 13, 2017

This morning, I and the other 1456 attendees of SVPCA 2017 received a useful document, SVPCA report_for attendees, which collects and analyses delegates’ feedback on the meeting. It prompted me to mention a few more thoughts of my own.

First, I didn’t like the shortening of the meeting, from the usual three or even four days to two and a half (or just two if you ignore the macroevolution symposium). But it’s apparent from the gathered feedback that nearly everyone disagrees with me on this.

My position may be an artifact of my idiosyncratic status on the edge of the field: SVPCA is pretty much my only physical (non-blog) contact with the vertebrate palaeontology community, so by the time I’ve taken a week off work for it, the more of that time I can use for it, the better. By contrast, people who spend most of their work-hours with other palaeontologists don’t have that incentive, and see a longer meeting as a financial burden. I’m guessing that if the survey had specifically asked for opinions on meeting length and then compared those opinions with people’s career stage, they’d find a strong correlation between amateur and other unusual statuses, and preferring a longer meeting.

Sadly (for me), it seems pretty clear how this one is going to go: the meeting is attended overwhelmingly by professionals of various career stages. Since the majority of those prefer the shorter meeting, I imagine Birmingham’s abridged programme will become the new normal.

Second thing: a lot of people complained that the posters were only up for the dedicated two-hour session, and quite a few didn’t like having a dedicated poster session at all. Once more, I find myself in a minority here. As someone presenting a poster, I very much appreciated having time dedicated to it. And I also liked that it was restricted to a specific slot, so I didn’t feel I had to spend the whole meeting babysitting the poster. Wine was provided for this session, which made it feel like a friendly, bustling session with plenty of science going on, and time to go and physically fetch the people who I specifically wanted to discuss my poster with.

So I would definitely support a dedicated two-hour poster session with wine at future meetings; though I wouldn’t object if the posters remained up in the background for the next day, if that was logistically easy. (It wasn’t in Birmingham.)

The third thing, which I forgot to mention on my feedback form, is that lightning talks need to be all together in a single session. These talks didn’t really work at Birmingham. By tagging two or three of them on the end of a regular session, they simply came across as a lesser versions of regular talks — tail-enders with no particular merit of their own.

But I do think lightning talks can work well: I’ve been in conferences (admittedly in computer science and library science rather than palaeo) where the lightning-talk sessions have been the best in the conference. The key is keeping all of them together in a single, dedicated session, and really keeping the pace up: whizzing through each talk within a strictly enforced five-minute time limit, and leaping from subject to subject. It can be exhilarating.

(There were specific reasons why it couldn’t be done this was at this year’s meeting — paucity of lightning-talk submissions, people’s difficult schedules and unexpected withdrawals all meant that the original plan couldn’t be adhered to. But I would hate to see lightning talks dropped from the conference because of their underwhelming impact this time around.)

The fourth thing is that I was not wholly convinced by the symposium. Given the scarcity of talk slots, their limited length, and the carefully blinded abstract review process, it seems inimical to invite a special anointed class of speakers who get twice as long and don’t have to go through review.

I might have been convinced despite this, had the quality of the talks been uniformly higher. But as one respondent to the survey wrote: “I was alarmed and disappointed to hear one presenter say that they had put their talk together the night before, and it showed”. It really did. Surely if being invited to give a double-length talk is anything, it’s an honour. People in receipt of that honour should either do their job to a level that merits it; or, if they don’t have time, politely decline and let someone else have the slot.

Finally, and least important, the annual dinner. This was a curry, with a good selection and far more food than we needed. But the report says “there have been a few comments […] that more people might attend if the food was more of a meat-and-two-veg type affair, and that some people would like to see a more formal, or more ‘special’ dinner”. For whatever it’s worth, I threw my hat in partly because it was a curry. In my experience, attempts at catering “special” dinners for large groups tend to produce mediocre food tarted up, which is why my group tends to skip the dinner.

But I’m glad I went this year. I liked the sense of being part of an ongoing community, of seeing the handover to next year’s host (Rob Sansom), hearing who the winners of the prizes were, and so on.


I can’t even count how many sauropod vertebra pictures we’ve posted here across the last ten years, but I am confident that the total comes to at least a lot. Here’s a picture from each year of the blog’s existence so far — let’s vote on which is the best!

November 15, 2007: Xenoposeidon week, day 1: Introducing Xeno

(Yes, there are eleven pictures: we’ve been running for ten years, but that includes both the end of 2007 and the start of 2017.)

So, which is the picture of the decade? Vote here (and let us know in the comments if we missed your favourite).


Amazingly (to me, anyway), SV-POW! is ten years old today. It was on 1st October 2007 that we published Hello world!, our first post, featuring a picture of what may still be our favourite single sauropod vertebra: the ?8th cervical of the Giraffatitan brancai paralectotype MB.R.2181. Of course, back then, we thought it was the type (it’s not), it was thought to belong to Brachiosaurus brancai (mea culpa), and the specimen number was HMN SII. A lot has changed in ten years, but the vertebra is still heart-breakingly beautiful.

Some other things have changed in those ten years, of course. Three of us started the blog, but one (Darren) has become a sleeping partner due to the enormous success of his other blog, Tetrapod Zoology. We began intending to be a picture blog, but we’ve ended up as a 50-50 blend of sauropod palaeontology and open-access advocacy. Along the way, I (Mike) got my Ph.D, and Matt moved from UC Merced to Western University of Health Sciences, where both he and his wife Vicki now have tenure. Darren meanwhile has carved out a unique niche for himself as a writer and consultant, and has his own cconference.

We never thought this blog would run for so long — I seem to remember the original plan was to make 52 weekly posts, then call it a day after one year. In fact, over the last ten years, we’ve posted 1160 articles, for an average of one every 3.15 days: more than twice as often as the weekly schedule that the blog title suggests. But not all those posts have included sauropod vertebrae — so, guessing that about half of them have, we’re more or less on target.

In the mean time, you have written 16820 comments, for a pretty healthy average of 14.5 per post. One of the things I’m proudest about regarding this blog is that we’ve only once had to shut a thread down because it became unproductive; and I think on only two other occasions have we had to issue a public warning. We have a fantastic community of commenters here, and my deeply felt gratitude goes out to you all.

Our most-read post at the time of writing is Every attempt to manage academia makes it worse (with 214,438 views), followed by Elsevier is taking down papers from (62,695), SV-POW! showdown: sauropods vs whales (35,944) and How big was Amphicoelias fragillimus? I mean, really? (35,531). These lead a list of 35 posts that have each garnered more than 10,000 views, contributing to an overall total of 3,573,821 views (which gives us an average of 3,080 views per post). We are alternately delighted, baffled and impressed that the world has shown such interest.

We have one or two things planned for this week of the 10th anniversary, but for this post I just want to leave it like this: THANK YOU ALL for reading, commenting and engaging with this blog. Thank you, palaeontologists for putting up with the open-access posts, and thank you scholarly communication specialists for putting up with the sauropods. We hope it’s been interesting, entertaining and sometimes thought-provoking; and we hope we can continue in the same vein. (We certainly have no plans to stop any time soon.)

We love you guys.
