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.
