Here’s that juvenile Barosaurus pectoral vertebra sequence anaglyph you ordered

March 7, 2022

I made this for my own amusement, and thought you guys may as well get to benefit from it, too.

Melstrom et al. (2016:figure 4). Pectoral vertebrae of a juvenile specimen of Barosaurus sp. (DINO 2921) from the Upper Jurassic Morrison Formation of Utah, U.S.A., in right lateral view (red-cyan anaglyph made from stereopair).



  • Melstrom, Keegan M., Michael D. D’Emic, Daniel Chure and Jeffrey A. Wilson. 2016. A juvenile sauropod dinosaur from the Late Jurassic of Utah, U.S.A., presents further evidence of an avian style air-sac system. Journal of Vertebrate Paleontology 36(4):e1111898. doi:10.1080/02724634.2016.1111898

    Helo. Are there any new data sugesting BYU9024 is from Supersaurus? If so, how that hypotesis would influence the size of the animal? It would be the same size as the supossed giant Barosaurus?

  2. Mike Taylor Says:

    Well, at the time of writing, a Supersaurus identity is the null hypothesis for BYU 9024: it was assigned to that genus by Jensen (1987) and that assignment has not to my knowledge been challenged in print in the subsequent 35 years. It’s on me and Matt to make the case for our alternative identification, and we’ve not yet got around to completing the paper that will do that. You can follow the in-progress manuscript at if you wish, but it’s presently stalled until I finish up a couple of other papers that that one will need to cite.
