My three-part series on the 'explosion of Iguanodon' is now complete and up on the Scientific American guest blog: part I is here, part II here, and part III here. Part III wraps things up and looks briefly at the social inertia that has held back our understanding of Iguanodon sensu lato, and also at the fact that some of the new names are unlikely to stand the test of time [the composite image above combines Greg Paul's illustrations of (at right, top to bottom) I. bernissartensis, Dollodon and Mantellisaurus, the skull of Dakotadon (at top left), and David Norman's skeletal reconstruction of the Mantel-piece].
