Аннотация: The ostracods are an ideal object for studies of microevolutionary process, in particular, the evolutionof sexual dimorphism, since they have a long and continuous fossil record, clearly expressed morphologicaltraits, the presence of sexual dimorphism, and numerous and clearly distinguished age stages. Thepaper reviews previous reports on the evolution of sexual dimorphism in ostracods and reports new data onthis phenomenon. For some ostracods, males have been shown to be the first to be involved in evolutionaryprocess from the Miocene to the present. The carapace hinge of the males differs from that in females due topedomorphic reorganizations. This phenomenon has been identified for the first time in the Mesozoic (LateCallovian) species Lophocythere acrolophos (Mikhailovtsement section, Ryazan oblast), the juvenile featuresof which continue to retain in the hinge of male carapaces.
