Trachyceras
Taxonomy
Trachyceras was named by Laube (1869) [Sepkoski's age data: Tr Carn-l Tr Carn-u Sepkoski's reference number: 302]. It is not extant. It is the type genus of Trachyceratinae.
It was reranked as Ammonites (Trachyceras) by Mojsisovics (1869); it was reranked as Anolcites (Trachyceras) by Mojsisovics (1893).
It was assigned to Ammonites by Mojsisovics (1869); to Tirolitinae by von Mojsisovics (1882); to Anolcites by Mojsisovics (1893); to Tirolitidae by von Mojsisovics (1896); to Trachyceratidae by Spath (1951), Kummel (1960), Creutzburg et al. (1966) and Tozer (1981); to Trachyceratinae by Tozer (1994); and to Ceratitida by Sepkoski (2002).
