Pterocerellidae

  • Pterocerellidae Bandel, 2007

Original Diagnosis of the family Pterocerellidae by Bandel, 2007, p. :

  • "The spire consists of angular whorls with two or three spiral keels and relatively wide apical angle. The outer lip has three spikes with keels on the upper side and a groove on the lower side and the siphon is twisted upwards and to the side. In case of Pterocerella the marginal spines of the aperture may branch and be interconnected to each other by a web, in case of Tessarolax the spines have no lamellae on their sides. The protoconch is relatively wide with relatively large and lowly coiled embryonic whorl, smooth rounded larval shell of more than 1.5 mm in width and height and abrupt transition from larval shell to the teleoconch. Species existed from Mid Cretaceous to the end of the Cretaceous."

Etymology: "The family is named after Pterocerella which represents the genus of the group that is best known."
