Pneumatic dorsal ribs in a selection of ornithodiran taxa. Clades that lack pneumatic ribs have been omitted, including non-dinosaurian dinosauromorphs, ornithischians, all early diverging sauropodomorphs, and numerous sauropods. The only included clade for which dorsal rib pneumaticity might be synapomorphic is Titanosauriformes.
Why study pneumatic vertebrae? Becuz I wubs dem. UwU This is one of those things that has been sitting in my brain, gradually heating up and getting denser, until it achieved criticality, melted down my spinal cord, and rocketed out my fingers and through the keyboard. Stand by for caffeine-fueled testifyin’ mode. Part 1: Why Study Pneumaticity Last item first: why you should study pneumaticity.
I was struck by a Mastodon post where classic game developer Ron Gilbert quoted film critic Roger Ebert as follows: The Muse visits during the act of creation, not before. Don’t wait for her.

My friend Toby Lowther wrote to me back in December to ask this question: As far as I understand it, the general rule for extant species is that it’s much easier to get much bigger underwater than on land, due to the role that water plays in supporting large bodies.
Long-time readers may remember that back in 2013, Matt and I played a game where we each designed a cover, in half an hour, for a book whose name was randomly generated.
The best thing about collaborations is that I get to work with amazing colleagues from around the world.
