Fig. 2From: Tooth replacement in the early-diverging neornithischian Jeholosaurus shangyuanensis and implications for dental evolution and herbivorous adaptation in Ornithischia3D reconstructions of premaxillary dentitions in Jeholosaurus. Premaxillary dentitions in the early juvenile CUGW VH132 in rostral (A) and dorsal (B) view. Right premaxillary tooth row in CUGW VH132 in lingual view (C). Left premaxillary tooth row in CUGW VH132 in labial view (D). Right premaxillary tooth rows in the late juvenile IVPP V12529 (E) and the subadult IVPP V15717 (F) in lingual view. Elements in the CT reconstructions are color coded as follows: functional premaxillary teeth, violet; replacement teeth, cyan; remnants of resorbed functional teeth, red; a thin layer of dentine (OF? ), blue. Scale bar equals 5Â mm (A-D) and 3Â mm (E-F)Back to article page
