(A) Left dentary tooth row of the early juvenile CUGW VH132 in labial transparent view; (B) Left dentary tooth row of IVPP V15719 in labial transparent view; (C) Left dentary tooth row of the late juvenile IVPP V12530 in labial transparent view; (D) Left maxillary tooth row of the late juvenile IVPP V12530 in labial transparent view; (E) Left dentary tooth row of the late juvenile IVPP V15718 in labial transparent view; (F) Right maxillary tooth row of the late juvenile IVPP V15718 in labial transparent view. Elements in the CT reconstructions are color coded as follows: functional maxillary teeth, yellow; functional dentary tooth, purple; replacement teeth, cyan; remnants of resorbed functional teeth, red.
