Timidonella is a genus of large middle Jurassic forams, with microspheric tests up to {{convert|8|mm|in}} in diameter. Smaller megalospheric tests may be fan-shaped or kidney-shaped to discoidal with breadths to slightly over 2 mm and a constant thickness equal to that of the proloculus. Chambers are numerous. The wall, microgranular calcareous, agglutinated.[http://www.gsi.ir/General/Lang_en/Page_48/Action_FirstPageView Timidonella GSI Foraminifera]
