Slender Oncoceratidae
Group of nautiloids / From Wikipedia, the free encyclopedia
Slender Oncoceratidae are those in the family Oncoceratidae, (Nautiloidea, Oncocerida) which have slender, commonly curved, shells. Some like Oocerina are gently curved, almost straight, and with only slight expansion. Others like Dunleithoceras are strongly curved with a more notable rate of expansion. Inclusion in this somewhat arbitrary category is based on illustrations in the Treatise Part K, 1964.
