Remarks: Jodotella veslensis represents the type-species of the genus described from the Thanetian of the Paris Basin, Central France based on a single isolated specimen by Morellet and Morellet (1913) . Further isolated material from the Paris Basin has been presented by Génot (1980) and Génot and Granier (2011) . Compilations of different Jodotella species with their biometrical data have been provided by Parente (1997 , tab. 2) and Dieni et al. (1985 , tab. 2). With respect to the biometric data from the Paris Basin ( Génot, 1980 ) and Sardinia ( Dieni et al., 1985 ), the Iranian specimens display smaller outer dimensions (D), and a reduced vertical spacing (h), while other parameters fall in the ranges reported from the species (e.g., d/D, p, ds). The occurrence in the Chehel Kaman Formation is the first record of the species from Iran and also in the Central Neotethysian area.
