Species / Strombus Albirupianus


Original description of Strombus albirupianus by Dall, 1890, p. 174:

  • "Shell of six or more whorls; nuclear part lost; whole surface spirally sculptured with feeble, elevated ridges, with wider interspaces; the ridges or threads coarser in front of the suture and near the canal; transverse sculpture on the early whorls of obscure ribs, chiefly apparent as stout tubercles, which on the later whorls are more or less vertically flattened and may number ten to fourteen or more on the last whorl; whorls turrited by the shoulder, which on the last whorl is subcarinate, with the tubercles on the carina, behind which the shell is somewhat excavated, the surface rising and somewhat appressed at the suture, which is very distinct; aperture narrow, not extended behind the carina of the body-whorl, toward which the expanded lip rises a little from the line of the shoulder, which last angulates the aperture; outer lip hardly reflected, somewhat thickened internally; inner lip lightly coated with callus, lirate behind, with small but distinct lirae; pillar a little twisted, with a faint siphonal fasciole; genital sulcus of the outer lip distinct, small and rather deep, quite anteriorly placed."

Locus typicus: "Claiborne Bluff, Alabama, USA" (Dall, 1890); Jacksonboro, Georgia (Woodring, 1959)

Stratum typicum: "Upper Eocene" (Dall, 1890); late Oligocene (Woodring, 1959)

History and Synonymy


Dall, 1903, p. 1400:

  • "It is well to state here that some of this limestone has long been in the National Museum with the label "White limestone of Claiborne, Alabama," furnished by an eminent paleontologist whose labels must in some way have got mixed. Several species included in this work have been described from these casts and referred to Claiborne, whereas they form a part of the Jacksonboro' fauna. Of these Mr. Vaughan by examining the collection has been able to make the following enumeration: Bulla petrosa Conrad; Strombus albirupianus Dall (p. 174); Cerithium georgianum Lyell; Calyptaea trochiformis Lamarck; Xenophora humilis Conrad; Amauropsis ocalana Dall (p. 377) and Ampullina strepostoma Heilprin, besides others not specifically identified."


Gardner, 1926, p. 558:

  • "This fine species [Strombus aldrichi] forms, in its characters, a sort of transition from S. albirupianus toward S. pugilis and S. granulatus of the Recent fauna, being more like the latter than the former."
  • "It [Strombus chipolanus]transmits several of the features of S. albirupianus and we fancy that they seem to reappear in the recent S. bituberculalus Lam."


Woodring, 1959, p. 189:

  • "Despite records to the contrary, the genus Strombus is unknown in the Eocene of America. Strombus albirupianus Dall (1890-1903, p. 174, pl. 12, figs. 2, 10, 1890) was said to occur in limestone of Jackson age at Claiborne Bluff, Alabama, but really occurs in limestone of late Oligocene age at Jacksonboro, Georgia (idem, p. 1400, footnote, 1903)."
