This is a lovely cosmic alignment: right after the 15th anniversary of this blog, Mike and I have our 11th coauthored publication (not counting abstracts and preprints) out today. Taylor, Michael P., and Wedel, Mathew J. 2022. What do we mean by the directions “cranial” and “caudal” on a vertebra?

They grow up so fast, don’t they? Matt and I, with our silent partner Darren, started SV-POW! fifteen years ago to the day, as a sort of jokey riff on NASA’s Astronomy Picture of the Day.

Back in June, I saw a series of tweets by sculptor and digital artist Ruadhrí Brennan, showing off the work he’d been doing on sculpting brachiosaurid skulls: Giraffatitan , Brachiosaurus (based on the Felch Quarry skull USNM 5730) and Europasaurus . Impressed, I asked if he would send a Giraffatitan skull, and here it is! You can immediately see two things: one, it’s good.

Various Internet rumours have suggested that the Archbishop is a super-giant sauropod one third larger than the mounted Giraffatitan specimen MB.R.2181 (formerly HMN SII). This is incorrect.

It is said that, some time around 1590 AD, Galileo Galilei dropped two spheres of different masses from the Leaning Tower of Pisa[1], thereby demonstrating that they fell at the same rate. This was a big deal because it contradicted Aristotle’s theory of gravity, in which objects are supposed to fall at a speed proportional to their mass.

Here are cervicals 4 and 8 from MB.R.2180, the big mounted Giraffatitan in Berlin. Even though this is one of the better sauropod necks in the world, the vertebrae have enough taphonomic distortion that trying to determine what neutral, uncrushed shape they started from is not easy.

Long before Matt and others were CT-scanning sauropod vertebrae to understand their internal structure, Werner Janensch was doing it the old-fashioned way.

I’ll see your face-of-the-blessed-virgin-in-a-waffle and raise you the fourth dorsal vertebra of the Giraffatitan brancai paralectotype BM.R.2181 (formerly HMN S II) in a dandelion leaf: {.alignnone .size-full .wp-image-16141 loading=“lazy” attachment-id=“16141” permalink=“http://svpow.com/2019/06/30/its-a-miracle/img_20190629_131844/” orig-file=“https://svpow.files.wordpress.com/2019/06/img_20190629_131844.jpg” orig-size=“1600,1200”
