Genus Acriclymenia Bogoslovskii 1975
Acriclymenia is a clymeniid ammonite that was extant from 367.6 to 366.8 million years ago during the Late Devonian. The type, and only know species Acriclymenia thaumasta was named by Bogoslovsky in 1975.
The shell, or conch, of Acriclymenia is a lenticular oxycone with a ventral keel accompanied by longitudinal grooves, a moderately narrow umbilicus, and an unusually high ventral saddle. As with other clymeniids Acriclymenia has a dorsal siphuncle the runs along the inner, concave, rim of the whorls.
The genus Acriclymenia is a member of the Carinoclymeniidae which also includes Carinoclymenia, Karaclymenia, and Pinacoclymenia, and may be a junior synonym of Carinoclymenia.
