Olenellus
Taxonomy
Olenellus was named by Hall (1861) [Sepkoski's age data: Cm Boto-l Cm Tojo-u Sepkoski's reference number: 81,885]. Its type is Olenus thompsoni.
It was reranked as Holmia (Olenellus) by Peach (1894); it was reranked as Mesonacis (Olenellus) by Peach (1894).
It was assigned to Mesonacis by Peach (1894); to Holmia by Peach (1894); to Mesonacidae by Walcott (1910); to Olenellidae by Riccio (1952), Palmer and Halley (1979) and Whittington et al. (1997); to Olenellida by Sepkoski (2002); and to Olenellinae by Palmer and Repina (1993), Palmer (1998), Lieberman (1998), Lieberman (1999) and Skovsted (2006).
