Article: A tergomyan mollusc from the Upper Cambrian of Wales

Bellerophon cambriensis from the Upper Cambrian of North Wales is redescribed as the type species of the new genus Telamocornu. Unlike most similarly coiled molluscs of this age, apertural sinuses are present which permit both a functional morphological interpretation of it as an untorted mollusc with the apex of the shall oriented anteriorly, and directly support assignation of Telamocornu to the Order Cyrtonellida of the Class Tergomya.
