I’ve mentioned my ardent love for the Big Bone Room at BYU before. One of the cool things that you can find there and nowhere else is BYU 9047, the holotype of Cathetosaurus lewisi , referred in 1996 to Camarasaurus . In referring to the beast as Cathetosaurus in the title I’m not casting aspersions on that referral. I’m just wondering.
Just got back my supervisor’s comments on my draft dissertation front-matter. Looks like I’m not going to be able to go with my chosen title.

Brachiosaurus: uglier than you think (we’re sorry, but it’s true). UPDATE: Fig. 1 from Witmer (2001) showing hypothesized position of the fleshy nostrils in Brachiosaurus. How awesome was our trip to Germany?

Welcome to the third and climactic episode in my HMN SII:D8 trilogy. If the unique spinoparapophyseal lamina and total lack of infradiapophyseal laminae featured in the first two episodes were not enough to creep you out, then this ought to do it: the ACPLs of this vertebra have great big holes in them! Unfortunately, my photos of this are terrible.
Just when you thought it was safe to go back into the Humboldt bone-room … hot on the heels of Part 1: Spinoparapophyseal Laminae!, comes another dose of terror thanks to everyone’s favourite mid-to-posterior brachiosaurid dorsal vertebra, HMN SII:D8. First, here is a pretty picture of the whole vertebra in right lateral view: {.aligncenter .size-full .wp-image-241 loading=“lazy” attachment-id=“241”
Of all the sauropod vertebrae in the world, perhaps the single most intriguing is a dorsal vertebra of the Brachiosaurus brancai type specimen HMN SII. It was designated the 20th presacral (i.e. 7th dorsal) by Janensch (1950), but that was on the assumption that the dorsal column consisted of 11 vertebrae.
Unbelievably, despite the fact that it is one of my favorite places in the world, despite the fact that it is just 10 fast hours away by car, across some of the most desolate and beautiful country on the planet, I have not been to BYU since the fall of 2005. The highlight of my last trip was spending a little quality time with the Dry Mesa Supersaurus cervical. You’ve seen it here before so you know it’s dimensions…sorta.
