Scanning Electron Microscope photographs of Siphonodella cooperi and Siphonodella lobata suggest that basal pits decrease in size after having reached a maximum. Analysis of biométrie data and computed regression lines confirm this. The phenomenon is explained by postulating migration of the plane of separation between the conodont and the basal plate, downwards in the holoconodont.
