Ananorites
Encyclopedia
Ananorites is an extinct cephalopod 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 nekton
ic (swimming) stalking marine predator that spent its time hunting above the sea floor.
