anatomical record cover

Juan Daza asks: Can you identify this lizard?

He continues:

If you have no idea, it’s not because it’s not an Anolis; in fact, this is an imaginary lizard that was reconstructed based on the remains of a 110 my old fossil from the Gobi Desert and a mosaic of features from different living geckos such as Agamura persica, Pachydactylus rangei, Teratoscincus przewalskii, Hemidactylus turcicus, and Coleonyx variegatus (and check the dromeosaurids roosting at twilight).  This digital illustration drawn by Stephanie Abramowicz is the cover of a March Special Issue from the Anatomical Record: New Advances In Morphology and Evolution of Living and Extinct Squamates [freely available at: http://onlinelibrary.wiley.com/doi/10.1002/ar.v297.3/issuetoc].

The idea of a volume like this started with James D. Gardner and Randall L. Nydam. They wanted to put a collection of papers from the Paleo-session of the past World Congress in Vancouver. Instead, they ended up editing another multi-authored volume entitled: Mesozoic and Cenozoic lissamphibian and squamate assemblages of Laurasia (Palaeobiodiversity and Palaeoenvironments, 93(4), Special Issue).

This volume took a different approach, and we (Scott Miller and I) put together herpetologists and paleontologists from around the world in a volume to present new ideas about morphology and evolution of squamates. This volume is a collection of 18 papers about paleontology, functional morphology, and gross anatomy of lizards and snakes, and includes recent findings from researches from 12 countries (USA, Canada, Colombia, Brazil, Argentina, Spain, France, Italy, Germany, Slovakia, South Africa, and New Zealand).

So please feel free to browse this volume that includes original research papers about the fossil record of lizards and snakes, anatomy of the chameleon’s atlantoaxial complex, pedal grasping capabilities, and pectoral girdle anatomy of anoles, fossil record of the Gekkota, cranial joints of squamates, hemipeneal morphology, brille formation, cranial joints, ancestral morphology and niche modeling of rhineurids, Anguimorpha, and the jaw musculature, and gut morphology of snakes. I hope you find this stimulating and pick morphology today, for a change.
