Publié in Sauropod Vertebra Picture of the Week

My talk (Taylor and Wedel 2019) from this year’s SVPCA is up! The talks were not recorded live (at least, if they were, it’s a closely guarded secret). But while it was fresh in my mind, I did a screencast of my own, and posted it on YouTube (CC By). I had to learn how to do this for my 1PVC presentation on vertebral orientation, and it’s surprisingly straightforward on a Mac, so I’ve struck while the iron is hot.

And so the series continues: part 9, part 10 and part 11 were not numbered as such, but that’s what they were, so I am picking up the numbering here with #12. If you’ve been following along, you’ll remember that Matt and I are convinced that BYU 9024, the big cervical vertebra that has been referred to Supersaurus , actually belongs to a giant Barosaurus . If we’re right about, then it means one of two things: either

Since the previous installment of this epic, we’ve taken two brief digressions on how little importance we should attach the colours of bones in our photographs when trying to determine whether they’re from the same individual: cameras do lie, and in any case different bones of the same individual can age differently.

Here’s a bit of light relief, in the middle of all those looong posts about Supersaurus and its buddies. When Matt and I were at NAMAL on the last day of the 2016 Sauropocalypse, we took a bunch of tourist shots. Two of them were of a skull and first three cervical vertebrae from what I take to be Diplodocus or something close, and happened to be from sufficiently close angles that they make a pretty good anaglyph.

Having surveyed what we know from the published literature about Jensen’s Big Three sauropods, and what Matt and I concluded about its big cervical BYU 9024, and having thought a bit more about the size of the BYU 9024 animal, we’re getting to the point where we can consider what all this means for Jensen’s taxa.

In part 2, we concluded that BYU 9024, the large cervical vertebra assigned by Jensen to the Supersaurus holotype individual, is in fact a perfectly well-behaved Barosaurus cervical — just a much, much bigger one than we’ve been used to seeing.

Last time, we reviewed what’s known about Jensen’s three giant sauropods based on published papers (and one abstract). This time, I want to talk a bit about what Matt and I have discovered, and intend to publish when we get around to it. The Three Baro Jacket It all followed on from our work on Barosaurus (which for now remains available only as a preprint, becalmed as it is in the peer-review doldrums — mostly my fault). Because of

It’s time to revisit everyone’s favourite trio of apocryphal super-sized sauropods! (Yes, we’ve talked about this before, but only very briefly, and that was nearly eleven years ago.

You’ll remember that we’ve been playing with CM 555, a subadult apatosaurine of indeterminate species, though John McIntosh assigned it to Brontosaurus (then Apatosaurus ) excelsus . At the start of the week, we had the centra and neural arches of cervicals 1-14, plus there were some appendicular elements on a shelf that we’d not yet gone to. But then today, Matt found this drawer: {.alignnone .wp-image-15853 .size-full
