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

To my shock, I find that we seem never to have posted Bob Nicholls’ beautiful sketch Hello, ladies! on SV-POW!. His recent tweet reminded me about this piece, so here it is! {.alignnone .size-full .wp-image-15878 loading=“lazy” attachment-id=“15878” permalink=“http://svpow.com/2019/03/28/hello-ladies/nicholls2013-barosaurus-hello-ladies/” orig-file=“https://svpow.files.wordpress.com/2019/03/nicholls2013-barosaurus-hello-ladies.jpeg”

Suppose that I and Matt were right in our SVPCA talk this year, and the “ Supersaurus ” cervical BYU 9024 really is the C9 of a gigantic Barosaurus . As we noted in our abstract, its total length of 1370 mm is exactly twice that of the C9 in AMNH 6341, which suggests its neck was twice as long over all — not 8.5 m but 17 m. How horrifying is that?

Long-time SV-POW! readers will remember that three years ago, full of enthusiasm after speaking about Barosaurus at the Edinburgh SVPCA, Matt and I got that talk written up in double-quick time and had it published as a PeerJ Preprint in less than three weeks. Very quickly, the preprint attracted substantive, helpful reviews: three within the first 24 hours, and several more in the next few days.

UPDATE 19 May 2016 I belatedly realized that I caused some confusion in the original version of this post.

I love Utah. I love how much of the state is given over to exposed Mesozoic rocks.
