Matt’s drawn my attention to a bizarre fact: despite 17 separate posts about Xenoposeidon on this blog (linked from here and here), we’ve never shown a decent scan of Lydekker’s (1893) original illustration of NHMUK PV R2095, the partial mid-to-posterior dorsal vertebra that since Taylor and Naish (2007) has been the holotype specimen of Xenoposeidon proneneukos — and since Taylor (2018) has been known to represent a

Today sees the publication of the monster enantiornithine Mirarce eatoni (“Eaton’s wonderful winged messenger”) from the Kaiparowits Formation of Utah, by Jessie Atterholt, Howard Hutchinson, and Jingmai O’Connor. Not my critter, not my story, but it is SV-POW!-adjacent. (Just here for the paper?

The more I look at the problem of how flexible sauropod necks were, the more I think we’re going to struggle to ever know their range of motion It’s just too dependent on soft tissue that doesn’t fossilise.

I wasted some time today making memes. I blame the Paleontology Coproliteposting group on Facebook.

In a comment on the last post, Mike wrote, “perhaps the pneumaticity was intially a size-related feature that merely failed to get unevolved when rebbachisaurs became smaller”. {.wp-image-6447 .size-large aria-describedby=“caption-attachment-6447” loading=“lazy” attachment-id=“6447” permalink=“http://svpow.com/2012/06/28/hot-sauropod-news-part-1-rampant-pneumaticity-in-saltasaurines/caudal-pneumaticity-in-saltasaurines-cerda-et-al-2012-fig-1/”

An important paper is out today: Carpenter (2018) names Maraapunisaurus , a new genus to contain the species “ Amphicoelias ” fragillimus , on the basis that it’s actually a rebbachisaurid rather than being closely related to the type species Amphicoelias altus . {.size-full .wp-image-15433 aria-describedby=“caption-attachment-15433” loading=“lazy” attachment-id=“15433”
