I was going to write a bit more about my recent paper The Concrete Diplodocus of Vernal (seriously, go and read it, you’ll like it, it’s fun). But then something more urgent came up. And here it is! {.alignnone .size-full .wp-image-20828 attachment-id=“20828”

I imagine that by now, everyone who reads this blog is familiar with Mark Witton’s painting of a giant azhdarchid pterosaur alongside a big giraffe.

If we accept that the distinctive ventral projections of the gigantic and ventrally displaced cervical ribs of apatosaurs were likely the base of some form of soft-tissue rugosity — such as keratinous horns like those of rhinos — then does it follow that those necks were used in combat as we suggested? Maybe, maybe not. As scientists, we are always open to other hypotheses.

I just read Mark Witton’s piece on the new new titanosaur Rukwatitan (as opposed to the old new titanosaur Dreadnoughtus ). I was going to write something about it, but I realised that Mark has already said everything I would have, but better. So get yourselves over to his piece and enjoy the titanosaurianness of it all!

Mark Witton, pterosaur-wrangler, Cthulhu-conjurer, globe-trotting paleo playboy and all-around scientific badass, drew this (and blogged about it): I liked it, but I thought it could use some color, so I hacked a crude version in GIMP and sent it to Mark with a, “Hey, please put this on a t-shirt so I can throw money at you” plea. Lo and behold, he did just that. You can get your own from Mark’s Zazzle store.
