Genus: | Hemicosmorthoceras Foerste (1925) |
Hemicosmorthoceras was named by Foerste (1925). It was assigned to Orthocerida by Teichert et al. (1964); and to Endocerida by Sepkoski (2002).[2]
The shell is usually long and may be straight ("orthoconic") or gently curved. In life, these animals may have been similar to the modern squid, except for the long shell.
Fossil distribution is exclusive to Sardinia, Austrian Alps.
