Scampanella cornuta Forchheimer & Stradner, 1973

Scampanella cornuta Forchheimer & Stradner, 1973


Species of Scampanella have a distal tier with smooth parallel sides and a very low cone with two spines at about 45°. The ratio of height to the width of species [excluding spines and collar] is between 1.5 to 2.0 whiles the ratio of distal tier to the cone is about 2.0. The specimen illustrated here has only one spine at 45° and the other spine is possibly broken off. All the dimensions of the illustrated specimen are compatible with holotype measurements [without spines].

Scampanella cornuta is distinguished from Scampanella magnifica Perch-Nielsen in Perch-Nielsen & Franz (1977) and Scampanella asymmetrica Perch-Nielsen in Perch-Nielsen & Franz (1977) by having 2 spines at about 45° whereas the latter species has only one amalgamated spine aligned with the length of the species. Moreover, Scampanella asymmetrica further differentiated from Scampanella cornuta by being asymmetrical and having a ratio of height to width [excluding spines and collar] over 2 whereas Scampanella cornuta has between 1.5-2.0. The ratio of distal tier to the cone is about 1.2 in Scampanella magnifica whilst it is about 2 in Scampanella cornuta.
