Grandostoma: An additional bellerophontiform mollusc with circumbilical retractor muscle attachment areas (Gastropoda, Bellerophontoidea)

Journal of the Czech Geological Society, volume 41 (1996), issue 3-4, 223 - 228

Grandostoma Horný, 1962, an Ordovician bellerophontiform mollusc, has been recognized as a gastropod with circumbilical retractor muscle insertions comparable to those in Bellerophon. The Subfamily Grandostomatinae is abandoned and the genus Grandostoma> is tentatively located in the Subfamily Bucaniinae (Gastropoda, Bellerophontoidea, Bellerophontidae). The mode of life of Grandostoma bohemicum, including shell repair, is discussed.
