POTENTIAL SUBJECTIVE JUNIOR SYNONYMS. — (according to Landau et al. 2013) Cerithium bidentatum Defrance in Grateloup, 1832; Potamides lignitarum var. sulfurea Sacco, 1888 ; Potamides lignitarum var. cingulatior Sacco, 1888 ; Potamides lignitarum var. planulata Sacco, 1888 ; Potamides colligens Sacco, 1888 ; Potamides colligens var. fasciculata Sacco, 1888 ; Terebralia bidentata var. cingulatior Sacco, 1895 ; Terebralia bidentata var. margaritifera Sacco, 1895 ; Terebralia vignali Cossmann, 1906 ; Cerithium ( Clava ) bidentatum var. fusiformis Schaffer, 1912 . Terebralia dertonensis ( Sacco, 1888) and its variations is most probably just a morphotype of T. lignitarum with predominant axial sculpture. Terebralia palustris lineata Borson, 1821 seems to be another morphotype of T. lignitarum with predominant axial sculpture and marked spiral grooves ( Landau et al. 2013).

PALAEOENVIRONMENT. — Plaziat et al. (2001) mention that it is possible that this species had not yet developed an exclusive association with mangrove environments, as its distribution largely exceeded that of Avicennia . Stable isotope data from estuary environments of the Korneuburg Basin ( Austria) in Latal et al. (2006) indicate a preference for brackish-water environments. Terebralia lignitarum coexisted from the late Oligocene (Chattian) to the earliest Miocene (Aquitanian) with T. subcorrugata in the Aquitaine Basin (SW France) and in the Mesohellenic Basin (NW Greece). From the Burdigalian on, it is frequently found associated with T. duboisi ( Landau et al. 2013) .

DISTRIBUTION. — North-eastern Atlantic. Early Miocene of France ( Cossmann & Peyrot 1922; Lozouet et al. 2001); Middle Miocene (Langhian and Serravallian) of France ( Cossmann & Peyrot 1922; Glibert 1949). Tortonian of Portugal ( Pereira da Costa 1866). — North Sea. Late Early Miocene (early Hemmoorian) ( Moths et al. 2010). — Proto-Mediterranean Sea. Oligocene (late Rupelian to early Chattian) and early to Middle Miocene of Turkey ( Mandic et al. 2004; İslamoǧlu 2008; Landau et al. 2013). Late Oligocene (Chattian) and Early Miocene (Aquitanian) of Greece ( Harzhauser & Kowalke 2001; Harzhauser 2004; Thivaiou et al. 2019) and Italy ( Sacco 1895). Late Miocene (Tortonian – early Messinian) of Italy ( Sacco 1895; D’Amico et al. 2012) and Greece ( Dermitzakis 1972; E. K. pers. obs.). — Paratethys Sea.Egerian (Chattian-Aquitanian) of Máriahalom in Hungary ( Báldi & Steininger 1975; Janssen 1984). Early Burdigalian (Eggenburgian) and late Burdigalian (Karpatian) of Austria ( Steininger et al. 1971; Harzhauser 2002). — Early Indian Ocean.Occurrences described by Vredenburg (1928) from the Burdigalian of Pakistan might rather represent another species ( Harzhauser et al. 2017).

REMARKS

This species was intensively discussed by Landau et al. (2013). The list of subjective synonyms (as presented above) is a result of the morphological variability and wide geographical distribution of the species.
