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.

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.
