WebScaphitidae and Baculitidae arose, cannot be called a stem group. The existing terminology is, therefore, not adequate for describing the evolutionary patterns or processes of completely extinct taxa. The aim of this paper is to demonstrate the need for expanding the cladistic terminology by describing the phylogeny of the Hamitidae. Scaphitidae is a family of extinct cephalopods belonging to the family of heteromorph ammonites (suborder Ancyloceratina). There is a possible fossil record of them being the last ammonites with fossils dating to the Danian of the Paleocene in Denmark, The Netherlands, The US and Turkmenistan. tx hhsc holiday calendar
