As iconic as Brachiosaurus altithorax is, it’s known from surprisingly little material.

I was cleaning out my Downloads directory — which, even after my initial forays, still accounts for 11 Gb that I really need to reclaim from my perptually almost-full SSD. And I found this beautiful image under the filename csgeo4028.jpeg . Brachiosaurus altithorax holotype FMNH PR 25107 during excavation. The thing is, I have no idea where this image came from.

Eighteen months ago, I noted that the Carnegie Museum’s Diplodocus mount has no atlantal ribs (i.e. ribs of the first cervical vertebra, the atlas). But that the Paris cast has long atlantal ribs — so long the extend past the posterior end of the axis. There were two especially provocative comments to that post. First, Konstantin linked to a photo of the Russian cast (first mounted in St. Petersburg but currently residing in Moscow).

New paper out today with Logan King, Julia McHugh, and Brian Curtice, on pneumatic ribs in Apatosaurus and Brontosaurus (King et al. 2024). This one had an unusual gestation. In the summer of 2002 2022 I did a road trip to Utah and western Colorado with my friend and frequent collaborator Jessie Atterholt.

This is one of those things that has been sitting in my brain, gradually heating up and getting denser, until it achieved criticality, melted down my spinal cord, and rocketed out my fingers and through the keyboard. Stand by for caffeine-fueled testifyin’ mode.

I was struck by a Mastodon post where classic game developer Ron Gilbert quoted film critic Roger Ebert as follows: And Gilbert commented: In a reply, Gretchen Anderson said her favourite version of this is: I couldn’t find the original source for this, but as I was trying to track it down I ran into this, attributed to Pablo Picasso: When I mentioned these observations to Matt, he sent me a longer-form exposition of the same phenomenon,

I said last time that Jisc’s feeble transition-to-open-access report was the first of two disapointing scholarly-communication announcements that week. The second was of course the announcement that PeerJ has been acquired by Taylor and Francis. Matt and I have both been big fans of PeerJ since before it launched, and we were delighted to have our 2013 neck-anatomy paper in the first batch of articles published there.

In the first of two disapointing scholarly-communication announcements last week, Jisc announced its report on progress towards open access in the UK. The key finding is: But that’s not the part that disappoints me. Here’s the part that disappoints me: Sometimes I think people don’t know what “transitional” means.

My friend Toby Lowther wrote to me back in December to ask this question: It’s strange, isn’t it? The last I knew, Shonisaurus was the largest ichthyosaur, at about 20 m and 50 tonnes, and this is considerably bigger than any plesiosaur or mosasaur I know of. It’s up the sperm-whale size category, but not even close to the bigger baleen whales. Why not?

Long-time readers may remember that back in 2013, Matt and I played a game where we each designed a cover, in half an hour, for a book whose name was randomly generated.
