Tooth replacement phenomena in the lower vertebrates /

Abstract: towards the lips, that is, the anterior surface of an anterior tooth, or the lateral surface of a cheek tooth. Lingual: towards the tongue, that is, the posterior surface of an anterior tooth, or the medial surface of a cheek tooth, refers to that surface of a tooth facing along the tooth row towards the premaxillary or dentary symphysis, refers to that surface of a tooth facing along the tooth row away from the premaxillary or dentary symphysis, refers to the grinding or biting surface of the teeth, that imag… Show more

“…It accommodates the rounded distal edge of the root of the preceding tooth. The teeth are closely packed as in other neoceratopsians (Sereno, 2000) and appear to erupt in two, highly coordinated series of Zahnreihen (Edmund, 1960). The roots are elliptical in cross section and wider transversely than mesiodistally.…”

“…This smaller number of tooth germs developing along the dental lamina at any one time may relate to the speed of replacement. Crocodilians are thought to replace their teeth once a year [50], in contrast to squamata that have a much quicker turnover with replacement around 4 times a year [51]. The need for a series of developing tooth germs may therefore only be required in animals with higher turnovers.…”

“…The reason for the alternative loss of teeth anteriorly, without sign of replacement teeth, and the total loss of 4 teeth in the rear of the dentary section is unknown. It does not follow the usual wave pattern of replacement (Edmund 1960), so presumably losses were a postmortem occurrence prior to preservation. The medial surface of this mandible is separated by a long V -shaped gap, wider posteriorly but extending to the anterior tip, forming the mandibular channe1.…”
