History and Synonymy

2001

Description of Acantoxenophora by Steffen Kiel, 2001, p.80:

  • "The shell is small and conical, foreign objects are attached to the first three teleoconch whorls, or the imprints of these can be seen. From the fourth whorl onwards, attachment of objects ceases and the development of spines begins."

Bandel, 2007, p. 159:

  • "The type species is Acanthoxenophora sinuosa PERRILLIAT & VEGA, 2000, from the Maastrichtian Mexcala Formation in southern Mexico (KIEL & PERRILLIAT, 2001: fig. 5, 3–5). It has its teleoconch as well as the protoconch in shape quite close to those of Xenophora leprosa (MORTON, 1834) from the Campanian Coffee Sand of Mississippi (DOCKERY, 1993: pl. 20, figs. 1–4; KIEL, 2002: pl. 22, figs. 3–5). The ornament of the teleoconch is distinctive by bearing large spines in somewhat irregular orientation. They may point into different directions and are distributed in one growth zone and only a few in one whorls (KIEL & PERILLIAT, 2001). This differs from Stellaria, where these spines are on the basal keel, while they are on the sides of the whorls, also the shell is relatively broader. Acanthoxenophora existed during the Late Cretaceous not only in Mexico at the Maastrichtian, but also in northern Germany during the Middle Santonian (KIEL & KRÜGER, 2006)."
