Original Description of Rostellaria carinata by Mantell, 1822, p. 86:

"Turreted, spirally striated; whorls, eight or nine; ornamented with a row of tubercles; body of the lower volution strongly carinated above the middle, and terminating in a spinous process on the outer lip. The casts of this shell are composed of indurated marl of a glossy black colour, and but rarely occur in a perfect state. In some specimens portions of the shell are still visible, and these shew that the original was covered with minute transverse striae; the tubercles on the shell are more elongated than in the casts, assuming the form of ribs."

Locus typicus: Laughton, Lincolnshire County, East Midlands Region, England

Stratum typicum: Gault, Albian, lower Cretaceous

Localities: Ringmer, Norlington, East Sussex County, South East Region, England (Mantell, 1822)

Aporrhais carinata in Gardner, 1875, pl. V, fig. 1

Gardner, 1875:

(p. 125) "A slight modification of this species occurs in the Upper Gault, in which the posterior digit of the wing is shorter, straighter, and diverges outwards; the anterior spur is longer in proportion to the wing, and the tubercles seem less elongated. They occur usually in a crushed condition."
(p. 126) "This and A.marginata, Sow. are the most abundant Gastropods at Folkestone, ranging through all the beds of the Gault, and being frequently found in masses together."
