Family CONOCARDIIDAE Miller, 1889

bruguierei , Cardium – Deshayes, 1857-TraitElem: 45. Replacement name for Cardium elongatum J. Sowerby, 1815 (J. Sowerby 1815: 188, pl. 82, fig. 3), non Bruguière, 1789, nec Bosc, 1801, nec Montagu, 1803. — Type locality: Derbyshire, United Kingdom. — Type age: Lower Carboniferous. Listed by Hylleberg (2004: 412) in his catalogue of Cardiidae names. Although earlier authors had treated Cardium elongatum J. Sowerby, 1815 , as the type species (M) of the genus Conocardium Bronn, 1834 ( Bronn 1834: 92) (e.g., Branson et al., in Cox et al. 1969: N859), later authors have shown that Bronn (1834), while listing C. elongatum , had actually figured Cardium aliforme J. de C. Sowerby, 1827 , and Bronn’s later works confirmed this. As a result, Amler & Rogalla (2004: 314) concluded that Cardium aliforme J. de C. Sowerby, 1827 , should be regarded as the type species of Conocardium under ICZN Code Art. 70.3. Cardium elongatum J. Sowerby, 1815 , had been listed as a synonym of the still earlier Conchyliolithus rostratus Martin, 1809 (Branson et al., in Cox et al. 1969: N859). While Martin’s work was rejected for nomenclatural proposes because the principles of binomial nomenclature were not followed (ICZN Opinion 231, 1954b), Martin’s species name was later made available by J. Fleming (1828: 420) ( Rogalla & Amler 2006: 48). With the precedent set by Branson et al., in Cox et al. (1969), this species should now be known as Conocardium rostratum (J. Fleming, 1828) , with the Deshayes replacement name falling into its synonymy. — Current status: the earliest name for this species may well be Conocardium elongatum (J. Sowerby, 1815) (M. Amler, pers. comm., March 14, 2023).

konincki , Cardium – Deshayes, 1857-TraitElem: 48. Replacement name for Cardium irregulare de Koninck, 1841 ( de Koninck 1841; 89-90, pl. 4, fig. 14), non Eichwald, 1830. — Type locality: Visé, Belgium. — Type age: Carboniferous. Hylleberg (2004: 579, as “1853”, 569). Additionally unnecessarily renamed Conocardium digitatum Branson, 1942 ( Branson 1942: 388). Listed by Rogalla & Amler (2006: 39), without reference to the Deshayes replacement name. Oxyprora konincki (Deshayes, 1857) . — Current status: Conocardium konincki (Deshayes, 1857) .
