Iguanodontians lacked teeth on their premaxillaries, yet the rest of their teeth are clearly adapted for tearing and chewing plant material. Assuming an
iguanodontian pulled plant material into its mouth using teeth from the dentary but none of the premaxillary, what might their toothmarks on the plants have looked
like, especially in comparison to herbivores that have incisors for shearing on both upper and lower jawbones? What modern animals have a similar adaptation to
feeding and what do their toothmarks on plants look like?
