Everyone is familiar with Dryosaurus, Iguanodon, Ouranosaurus, and Camptosaurus, but work by David Norman, Dave Weishampel, Peter Galton, and a few other dinosaurologists have helped reconstruct the early evolution of Iguanodontia, finding Rhabdodontidae the most primitive iguanodonts and grouping dryosaurids with more advanced iguanodonts in Dryomorpha, while applying the name Ankylopollexia to the clade formed by basal iguanodonts more derived than Dryosauridae. Therefore, I thought it would be appropriate to ask what your favorite primitive iguanodont is.
