"Like the teeth of the recent iguana, the crown of the tooth is accuminated; the edges are strongly serrated or dentated; the outer surface is ridged, and the inner smooth and convex; and as in that animal the secondary teeth appear to have been formed in a hollow in the base of the primary ones, which they expelled as they increased in size. From the appearance of the fangs in such fossil teeth as are in a good state of preservation, it seems probable that they adhered to the inner side of the maxillae, as in the iguana, and were not placed in separate alveoli, as in the crocodile. [...] [T]he term IGUANODON, derived from the form of the teeth, (and which I have adopted at the sugges­tion of the Rev. W. Conybeare) will not, it is presumed, be deemed objectionable."
