  1. The suction mechanism of the pipid frog, Pipa pipa (Linnaeus, 1758)

    David Cundall, Edward Fernandez and Frances Irish

    Version of Record online: 25 MAY 2017 | DOI: 10.1002/jmor.20707

    The aglossan pipid frog, Pipa pipa, recruits its entire trunk during suction feeding on elusive prey by exploiting novel arrangements of buccopharyngeal dilators.

    A three-dimensional placoderm (stem-group gnathostome) pharyngeal skeleton and its implications for primitive gnathostome pharyngeal architecture

    A three-dimensional articulated gill arch skeleton of a 400-million-year-old placoderm fish is described. This adds to the diversity of feeding and respiratory structures in jawed vertebrate animals and informing hypotheses of gill arch evolution in the first jawed vertebrates.

  3. Phylogenetics and ecomorphology of emarginate primary feathers

    Brett Klaassen van Oorschot, Ho Kwan Tang and Bret W. Tobalske

    Version of Record online: 18 MAY 2017 | DOI: 10.1002/jmor.20686

    Primary feather emargination (E) covaries with mass and habitat type among 135 avian species. Pelagic species have very little or no emargination, suggesting they are under different aerodynamic selective pressures than terrestrial and coastal/freshwater species.

  4. Intercentrum versus pleurocentrum growth in early tetrapods: A paleohistological approach

    Marylène Danto, Florian Witzmann, Stephanie E. Pierce and Nadia B. Fröbisch

    Version of Record online: 18 MAY 2017 | DOI: 10.1002/jmor.20709

    Two divergent developmental patterns are observed in the presacral pleurocentrum of temnospondyls and stem-amniotes. In the former, the pleurocentrum arose from two dorsally located ossification centers while in stem-amniotes, it developed from two ventrally located ossification centers.

  5. Comparative musculoskeletal anatomy of chameleon limbs, with implications for the evolution of arboreal locomotion in lizards and for teratology

    Julia L. Molnar, Raul E. Diaz Jr., Tautis Skorka, Grant Dagliyan and Rui Diogo

    Muscles of left forelimb of chameleon (Chamaeleo calyptratus) in medial view, and inset showing detailed muscle anatomy of distinctive syndactylous manus. Considering the remarkable structural and functional modifications of the distal limb in chameleons, the number and attachments of muscles are surprisingly conservative.
