Species / Anchura Bakeri


Original description of Anchura bakeri by Richards, 1943, p. 27:

  • "Shell of medium size, spire elongate conical; whorls about six (estimated); very slightly convex; suture slightly impressed. Top portion of type not preserved. Prominent lateral ribs on each whorl, much more conspicuous on all except penultimate. Because of the incomplete preservation of the type, it is impossible to estimate the number of ribs. However, they are slightly closer together and apparently more numerous than in A. pontana Stephenson. The body whorl is covered with conspicuous spiral ribs separated by interspaces of irregular width. No riblets were observed in the interspaces. The crossing of the spirals and growth ridges produces a semi-cancellated appearance, although this is less conspicuous than in A. pontana. Aperture not visible. The outer lip is extended to form a lip-like structure which, unfortunately, is not perfectly preserved. It apparently had much the shape of the outer lip of A. pontana."

Locus typicus: Sayreville, Middlesex County, New Jersey, USA

Stratum typicum: Raritan Formation, upper Cenomanian, upper Cretaceous

Types: N.J.S.M. 10448
