The ammonites assigned to the family Pseudotissotiidae of the Wiedmann (Tübingen,Germany) and Goy, Carretero and Meléndez (Madrid, Spain) collections obtained from the Iberian Trough have been revised. New, mainly lower Turonian, specimens of the species Pseudotissotia sp., Choffaticeras (Choffaticeras) quaasi (Peron, 1904), C. (C.) pavillieri (Pervinquière, 1907), C. (C.) segne (Solger, 1903), C. (C.) sinaiticum (Douvillé, 1928), C. (Leoniceras) luciae (Pervinquiére, 1907), C. (L.) barjonai (Choffat, 1898), Wrightoceras llarenai (Karrenberg, 1935), W. munieri (Pervinquière, 1907), W. submunieri Wiedmann, 1975b, and Donenriquoceras forbesiceratiforme Wiedmann, 1960, have been also presented. In addition, we designate and refigure the lectotype of Pseudotissotia (Leoniceras) alaouitense Basse, 1937, and refigure the lectotype of P. barjonai Choffat, 1898. Studies on the morphologies and the geographical and temporal distributions of all of these species have led to the identification of several phylogenetic relationships between them, and to distinguish four main phases in the evolution of the family, characterized by the successive dominance of Choffaticeras (Choffaticeras), Choffaticeras (Leoniceras), Donenriquoceras and Wrightoceras with Donenriquoceras.
