1982 Clypeina merienda Elliott – Deloffre and Génot, p. 51, pl. 3, figs. 6-7.
1990 Uteria merienda (Elliott) – Radoičić, pl. 10, fig. 5.
Remarks: As the sections illustrated by Elliott (1968) from the Paleocene Sinjar Formation of Iraq were assigned to the genus Clypeina Michelin , they were interpreted as belonging to fertile laterals. “Reminiscent of Clypeina ”, they were referred to the sterile laterals of the genus Uteria Michelin showing two types of laterals, sterile and fertile ( Radoičić, 1990; Dieni et al., 1985, p. 26). This type of thallus structure is well discernible in the longitudinal section illustrated in Figure 11a, a View Fig specimen from Eastern Iran (Sistan Suture Zone). There may be one or two fertile whorls between the disc-like whorls of sterile laterals. The specimens from the Chehel Kaman Formation refer exclusively to fragments of sterile laterals. A comparative table of the different Uteria species, excluding U. merienda , has been provided by Deloffre et al. (1989, tab. 1). In fact, the new species described by Deloffre et al. (1989) as Uteria mexicana from the upper Paleocene can in our opinion not be differentiated distinctly from the Iraqi species and might be a possible junior synonym of the latter.
