A new study by Smyth and colleagues identifies pterosaur trackmakers and shows that several lineages of Jurassic and Cretaceous pterosaurs independently evolved to thrive in terrestrial ecosystems, foraging on foot rather than on the wing!

@sieri I wonder how size influences their capacity to reach this state of "getting enough lift from wind without moving"...
You mostly see relatively big birds (prey birds) do it, but I think that's more for ecological reasons (looking for preys).
It would be nice to have an aerodynamic breakdown of the interactions of morphology, mass, and lift.

The central part of a head, the glabella, is very . . . lobe-y. As an example, I have the silicified head of Acidaspis (Acidaspis) lesperancei Chatterton & Perry, 1983 from the Silurian of Canada. Find the middle part of the head, that is the glabella. The paired lobe-y bits to the side? Those are not eyes, those are bits of the glabella that have sort of budded off. #functionalmorphology #palaeontology #paleontology

The biological hammer is a modified mouthpart--the 2nd maxilliped. A strike with this hammer can produce a cavitation bubble. The mechanics are complicated, but the results aren't: these little bastards can crack glass in an aquarium. Or, a clam shell.

@ArthropodLegs Leaving aside ammonites, I think that the Mesozoic marine reptiles existed before barnacles were able to attach to vertebrates that replace their outer layer of skin. I think that barnacles started easy (the rock-like turtle shell), and after they mastered that, they moved on to more challenging hosts. #functionalmorphology #Palaeontology #paleontology #evolution

As Dolf Seilacher put it, whale barnacles are an evolutionary dream come true. The tiny, baby barnacle (nauplius) settles, not on a rock or shell, but on the whale itself. These barnacles have several different adaptation so that they don't just slough off as the whale's skin grows. #functionalmorphology

Nobody knows. Or at least nobody who would write it in a published paper. I like to imagine that the plucky Ixa uses the projections to prop open a predator’s mouth, preventing it from crushing it and depriving it of a tasty meal. Unfortunately, this is probably unlikely. #functionalmorphology
