 The holotype of Paranthodon , BMNH 47338 , was found in a layer of the Kirkwood Formation dated between the Berriasian and early Valanginian ages . It consists of the back of the snout , containing the maxilla with teeth , the posterior caudodorsal ramus of the premaxilla , part of the nasals , and some isolated teeth probably from the lower jaw . One additional specimen can be assigned to it based on the dentition , BMNH 47992 , including only isolated teeth sharing the same morphology as those from the holotype . However , the teeth do not bear any autapomorphies of Paranthodon , and were referred to an indeterminate stegosaurid in 2008 .
