Cephalopod development and evolution. Biological insight into ontogenesis as a guide to paleomorphology / Развитие и эволюция головоногих моллюсков. Биологический взгляд на онтогенез как руководство по палеоморфологии

Questions of morphological study addressing living and fossil organisms are briefly discussed. The importance of ontogenetic patterns and processes in evolutionary biology are viewed on the background of three special problems of cephalopod morphology: the reproductive system of octopods, the lower beaks of coleoids and ammonites, and the arm crown of the coleoids. <...>
