Rodzina Spathognathodontidae Hass, 1959

Opis

Biramous S0 element, other elements of S series with relatively short processes.
Despite the great time gap between the Carboniferous occurrences of conodonts with biramous symmetrical elements in the apparatus (Hindeodus and Synclydognathus) and similar Silurian Ozarkodina, it was proposed by myself that they represent the same clade. The occurrence of Synclydognathus in the early Famennian significantly reduces this gap and confirms the hypothesis of their close relationship. One of the new Famennian species appears closely similar in its apparatus organization to coeval Apatognathus, earlier classified among prioniodinids.
