A new tremataspidid genus Tyriaspis (type species T. whitei gen. et sp. nov.) is described from a new Upper Ludlovian locality at Ringerike, southern Norway. The genus is assigned to the subfamily Dartmuthiinae Robertson. Six specimens are known, thus allowing a fairly complete diagnosis and reconstruction of the species which has a flat head-shield with wing-like cornua and.

Three divisions, or subclasses, are involved, the Ammonoidea which are extinct and the Nautiloidea and Coleoidea which have modern representatives.

The Nautiloidea and Ammonoidea have external, chambered shells and are thus ectocochliate. The. Inappropriate The list (including its title or description) facilitates illegal activity, or contains hate speech or ad hominem attacks on a fellow Goodreads member or author.

Morphology, taxonomy, and classification of the order Eurypterida Burmeister, - Volume 63 Issue 5 - V. P. Tollerton.Cephalopod definition is - any of a class (Cephalopoda) of marine mollusks including the squids, cuttlefishes, and octopuses that move by expelling water from a tubular siphon under the head and that have a group of muscular usually sucker-bearing arms around the front of the head, highly developed eyes, and usually a sac containing ink which is ejected for defense or concealment.Cephalopod - Cephalopod - Form and function: Cephalopods vary from elongate, streamlined oceanic organisms to saccular, slow-moving bottom and drifting forms.

Their body plan is indicative in many ways of the habitat in which they dwell and their mode of life. The viscera of a generalized cephalopod are covered by a dome-shaped or elongated sheath of muscle, the mantle, which is connected with.
