TRILOBITE GENERA AND SPECIES LIST

Wallacia (Lamont, 1978)

Wallacia hendersoni (Norford, 1994)

Wanneria (Walcott, 1910)

Wanneria ? gracile (Walcott, 1910) = Nevadia gracile (Walcott, 1910)

Weeksina (Resser, 1935)

Weeksina unispina (Walcott, 1916b)

Wenkchemnia (Rasetti, 1951) [is a junior synonym of Bathyuriscus, fide ROBISON, 1976]. Note: Wenkchemnia is apparently a junior synonym of Bathyuriscus, fide ROBISON, 1976 according to Jell and Adrain, 2003. Fred Sundberg and others strongly believe that Wenkchemnia Rasetti, 1951 is a valid genus and that Dick Robison shouldn't have placed it in synonomy with Bathyuriscus Meek, 1873.  Both Sundberg & Robison stick to their positions, so the issue is unresolved. For our list, we will go with the genus that the author of the species uses. All species of Wenkchemnia should perhaps be called Wenkchemnia (?=Bathyuriscus) spp. for now.
