| Research Abstract |
A comparison of the histology of the tooth of rhinoceroses revealed a unique ameloblastic movement. We will research the South American fossils and compare their variation of the morphology and histology with other location and period. 2 genus of the Desmostylia which inhabited the same place for the same period. We are associating developmental study and ecological study. The incisor enamel band of the Proboscidea has been studied few examples, and the comparison with the molar enamel is enabled histological development and the molecular biologic study of Marsupials give a suggestion about generality and specialization in the formation of the mammalian jaws and teeth.
