Homalopoma
Taxonomy
Homalopoma was named by Carpenter (1864) [Sepkoski's age data: Tr Anis R Sepkoski's reference number: 797]. It is extant.
It was assigned to Liotiinae by MacNeil (1960); to Homalopomatinae by Keen (1960), Fleming (1966) and Kase (1984); to Colloniidae by Lozouet et al. (2001); to Archaeogastropoda by Sepkoski (2002); to Colloniinae by Pacaud and Le Renard (1995) and Bouchet et al. (2005); and to Turbinidae by Turner (1938), Durham (1944), Ladd (1982), Squires (1988), Todd (2001), Kiel (2006) and Squires (2008).
