Forms, size and time in ontogeny of Amphibians and Reptiles. In the life of an organism (ontogeny), phenotypic changes happen throughout the time. This contribution is a review of: a) terms and definitions used in studies of the ontogeny, b) the importance to distinguish between shape variation form (development) and size variation (growth); and c) the need to consider the real time (age) in which the ontogeny takes place. Based on available information about the ontogeny among tetrapods with emphasis in anurans and nonavians sauropsids, it is outlined the need to increase the information about the ontogeny for comparative studies. We denote the relevancy to get tables of development from which ontoegenetic variation and the study of three fundamental components of ontogenies (it forms - size-time) and the processes that the age organizes (development and growth) to contribute the paradigm of the Evolution of the Development.
