Mesozoic Miscellany #38

Research and Discoveries News

Pneumaticity and the evolution of birds. In a new research paper in Biological Reviews, now in advance online publication, a team led by Robert Benson examined the remarkable 12 unique lines of archosaurs who evolved pneumaticity in their skeletons. The authors "hypothesise that skeletal density modulation in small, non-volant, maniraptorans resulted in energetic savings as part of a multi-system response to increased metabolic demands. Acquisition of extensive postcranial pneumaticity in small-bodied maniraptorans may indicate avian-like high-performance endothermy."

An overview of the pterosaurs' remarkable variety of forms. A masters thesis by Karen Prentice, along with Marcello Ruta and Michael Benton, takes a thorough look at the entire pterosaur family tree to tease out evolutionary patterns. Among their findings: "there is no evidence that rhamphorhynchoids as a whole were outcompeted by pterodactyloids, or that pterosaurs were driven to extinction by the rise of birds."

Stuff I've linked to on Twitter in the last coupla weeks...
Paleoart of the Week
As it's been two weeks since the last big roundup, it's only fair that I share two pieces here, don't you think? The first comes from hadrosaur enthusiast and 3D artist Angie Rodrigues, who posted her new Lambeosaurus model on her blog this week. Incredible, and made even cooler by the fact that you'll be able to own it! That's right - just check out her shop at Shapeways to buy one of her figures.

This week, Mark Witton debuted his new site, which is packed with wonderful stuff, much of which hasn't been shared on his popular Flickr photostream. So, from Flickr, here's a dandy piece o' Wittonalia to celebrate this milestone.
Beautiful friends, The end
Also, see his Pterosaur.net post announcing his site.

  1. Of course, if you're gonna have a shark, it's gonna have a frikkin' laser beam* attached to its head.

    *I know, laser beam meaning emitted light, rather than the emitter, but that's the parlance! THANKS, Mike Myers.
