Ananorites
Ananorites is a genus of extinct cephalopods belonging to the ceratitd family Noritidae found in the Middle Triassic of the Himalaya. The shell is  thinly discoidal, evolute, and smooth; cross section highly compressed; venter narrowly rounded except at the late stage where sharp shoulders are developed. As with others of its kind, Ananorites was probably a nektonic (swimming) stalking marine predator that spent its time hunting above the sea floor. References
