Notoemys laticentralis, a basal pleurodiran turtle of the Upper Jurassic from South-Argentina, is reconsidered with respect to the evolutionary process of some structures : proportions of the skull, anatomy of the back skull, alone preserved, and of the neck. Comparison of these structures has been leaded in different groups of turtles, previously established as monophyletic. Before, some remarks are a basal pleurodiran turtle of the Upper Jurassic from South-Argentina, is reconsidered with respect to the evolutionary process of some structures : proportions of the skull, anatomy of the back skull, alone preserved, and of the neck. Comparison of these structures has been leaded in different groups of turtles, previously established as monophyletic. Before, some remarks are given, with examples, on the difficulty to establish the homologies, what appears in the comparisons. The family Notoemydidae is supported as distinct from the family Platychelyidae and considered as including Notoemys�������� laticentralis, N. zapatocaensis andNotoemys�������� laticentralis, N. zapatocaensis and Caribemys.
