History and Synonymy

2002

Kiel & Bandel, 2002:

• "Members of the Anchura clade first occur and have their highest diversity in the Atlantic Gulf plains and Pacific slope of North America (STEPHENSON 1941, 1952; SOHL 1960; DOCKERY 1993; ELDER & SAUL 1996). Helicaulax is considered to represent a subgenus of Anchura with long posterior spur and rostrum. PCHELINTSEV (1953) introduced Pugioptera as another subgenus with a dagger-like wing and no posterior spur and Rostellaria requieniana D'ORBIGNY, 1842 as type species. A rigorous revision is needed to corroborate the validity of this subgenus and even that of Helicaulax. It seems that Anchura is highly variable in shape and extent of its wing, posterior spur and rostrum. In contrast, the ornamentation of the body whorl formed by axial ribs and spiral cords with knobby intersections, seems very consistent through time and space. ELDER & SAtJL (1996) demonstrated that Anchura can be used for biostratigraphy. This also demonstrated the ability of Anchura to undergo rapid adaptations. Shape and size of wing, posterior spur and rostrum might be adaptations to their local environment and are therefore of low taxonomic value above species level. ELDER & SAUL (1996) pointed out that Anchura preferred fine grained sandy sediment of middle or outer shelf environments. This could explain its absence from the Umzamba locality, which represents near shore deposits."

Remark:

• The genus name Anchura had been used in a very broad sense over a long time in literature. It might be that several of the above species belong to different genera. This needs further investigation (U. Wieneke)
