Remarks.― Dubois (1908) only gave a short diagnosis of this species. Janensch (1911) provided an extensive description of material of this species obtained by the German Trinil expedition. Müller (1923) synonymised Crocodylus ossifragus with the extant Crocodylus siamensis Schneider, 1801. A full description of the material in the Dubois collection is given by Massimo & de Vos (2010).
