Cymbitidae is family of ammonite that lived during Sinemurian and Pliensbachian stages of Lower Jurassic.

[1] Ammonites belonging to this family had shells with sphaeroconic involute inner whorls that later during ontogeny become evolute and last whorl is highly eccentric.

Ornamentation was weak, as shell was smooth or plicate and only rarely there were lateral tubercules.

One more genus has been added there and it is Hyerifalchia Fucini, 1907, but this one is probably only a synonym of Cymbites.

[1] Ammonites of this family were found in Europe, US and Tunisia.
