In press materials on flight & metabolisms

   For those who are interested in biological research which can, without difficulty, be used as inights into archosaur metabolisms of pre-K/T feathered theropods and pterosaurs:
    A. Zubaid, G.F. McCracken, T.H. Kunz, in press (Oxford University Press), Functional & evolutionary ecology of bats.
This stunning volume -- it will be the Currie/Padian + Farlow/Brett-Surman of its domain -- has a fascinating chapter by Ariovaldo P. Cruz-Neto and Kate E. Jones, Exploring the evolution of the basal rate of metabolism in bats. Although not pterosaurs, of course,  bats are flapping fliers, and, together with the early 1985 paper by Kevin Padian (The origin and aerodynamics of flight in extant vertebrates), and his 1987 further discussion (A comparative phylogenetic and functional approach to the origin of vertebrate flight), bats and fossil pterosaurs provide the paleobiologist with wonderful tools for grasping the inferred ecomorphologies of the other group of fliers, the feathered theropods who took wing.
    Another in-press paper to look for from Biological Reviews (Cambridge Philosophical Society) is Kate E. Jones, Andy Purvis, Ann MacLarnon, Olaf R.P. Bininda-Emonds, Nancy B. Simmons, A phylogenetic supertree of the bats (Mammalia: Chiroptera).
    The flight mechanisms/osteologies of flying theropods, pterosaurs, and bats differ, yet share homologies related to flight...and, I think, diet. (Although only a guess, it may be that bats displaced certain flying theropods from econiches they now occupy.) The paleo history of the bats is fragmentary, but they are a worthy realm to find insights.
