Tetragonites

Cephalopoda - Ammonitida - Tetragonitidae

Taxonomy
Lytoceras (Tetragonites) was named by Kossmat (1895) [Sepkoski's age data: K Apti-u K Maes-u Sepkoski's reference number: 730]. It is the type subgenus of Tetragonitaceae.

It was reranked as Tetragonites by Matsumoto (1959), Murphy (1967), Henderson (1970), Förster (1975), Cooper (1978), Cooper and Kennedy (1979), Renz (1982), Wright and Kennedy (1984), Kennedy (1994), Kennedy (1995), Wright et al. (1996), Geyer et al. (1997), Sepkoski (2002), Kennedy and Jolkicev (2004), Kennedy (2005), Szives (2007), Kennedy et al. (2007), Hoffmann (2010), Shigeta (2016), El Qot (2018), Gautam et al. (2019) and Shigeta and Maeda (2023).

It was assigned to Lytoceras by Kossmat (1895) and Paulcke (1907); to Litoceras by Böse (1923); to Ammonoidea by Sepkoski (2002); to Tetragonitinae by Matsumoto (1959), Murphy (1967), Henderson (1970), Renz (1982), Wright et al. (1996), Kennedy et al. (2007), Hoffmann (2010) and El Qot (2018); and to Tetragonitidae by Förster (1975), Cooper (1978), Cooper and Kennedy (1979), Wright and Kennedy (1984), Kennedy (1994), Kennedy (1995), Geyer et al. (1997), Kennedy and Jolkicev (2004), Kennedy (2005), Szives (2007), Shigeta (2016), Gautam et al. (2019) and Shigeta and Maeda (2023).
