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. So what has happened?
What if I told you that when Matt was in BYU collections a while ago, he stumbled across a cervical vertebra — one labelled DM/90 CVR 3+4, say — that looked like this in anterior view?
This is RAM 1619, a proximal caudal vertebra of an apatosaurine, in posterior view. It’s one of just a handful of sauropod specimens at the Raymond M. Alf Museum of Paleontology. It’s a donated specimen, which came with very little documentation.
Fiona made me a cake for tomorrow. She asked me if the flowers were OK. I said there were flowering plants at the end of the Cretaceous, so this is acceptable so long as we interpret the sauropod as a titanosaur.
Taylor 2015: Figure 8. Cervical vertebrae 4 (left) and 6 (right) of Giraffatitan brancai lectotype MB.R.2180 (previously HMN SI), in posterior view. Note the dramatically different aspect ratios of their cotyles, indicating that extensive and unpredictable crushing has taken place. Photographs by author. Here are cervicals 4 and 8 from MB.R.2180, the big mounted Giraffatitan in Berlin.
Bonaparte’s (1999) description of the Early Cretaceous sauropod Agustinia ligabuie was notable for its identification of nine bony fragments as representing dermal armour, which he classified into Types 1–4. Here are some examples: Consequently, Augustinia was for many years restored as uniquely spiky, a sort of “stegosaur sauropod”: But Bellardini and Cerda (2017) showed that […]
Picture is unrelated. Seriously. I’m just allergic to posts with no visuals. Stand by for more random brachiosaurs. Here’s something I’ve been meaning to post for a while, about my changing ideas about scholarly publishing. On one hand, it’s hard to believe now that the Academic Spring was almost a decade ago.
Gilmore (1936:243) says of the mounted skeleton of Apatosaurus louisae CM 3018 in the Carnegie Museum that “with the skull in position the specimen has a total length between perpendiculars of about 71 feet and six inches.
If you’ve been around SV-POW! for long, you’ve seen me in this shirt: I found it on Amazon.
Oh, hey, so you know how the most tedious thing you can ever hear is someone recounting one of their dreams? I want to tell you about a dream I had last night.
Xinjiangtitan when originally described, from Wu et al. (2013) We’re way late to this party, but better late than never I guess. Wu et al. (2013) described Xinjiangtitan shanshanesis as a new mamenchisaurid from the Middle Jurassic of China. At the time of the initial description, all of the dorsal and sacral vertebrae had been uncovered, as well as a handful of the most posterior cervicals and most anterior caudals.
