Timidonella is a genus of large middle Jurassic forams, with microspheric tests up to 8 millimetres (0.31 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.[1]

Timidonella has been found in the middle Jurassic of France, Italy, Sardinia, Iran, and Madagascar.[1] Spiraloconulus, Streptocyclammina, and Spirocyclina are among related genera.
