Mollusca (Pt 3)- Cephalopods- Invertebrate Paleontology | GEO GIRL

The Cephalopoda class of Mollusks! This video covers cephalopod morphology, anatomy, classification, ecology, and evolution. Cephalopods are animals such as octopuses, nautiluses, cuttlefish, squids, and the extinct ammonoids (or ammonites), which are very important index fossils for the Paleozoic and Mesozoic Eras. The major subclasses of cephalopods include: Nautiloidea, Endoceratoidea, Actinoceratoidea, Bactritoidea, Ammonoidea, and Coleoidea. I discuss in detail the internal and external features of cephalopod shells, including nautiloid, goniatitic, ceratitic, & ammonitic ammonoid suture patterns. I also discuss hetermorph ammonoid shell morphologies and planispiral forms and their evolutionary trends.
