The Reitlingerellidae are an assemblage of tubular microfossils known from the Cambrian and Ordovician periods (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Shell free, consisting of narrow tubular chamber of constant diameter (0.016–0.017 mm) coiled in expanding spire, cylindrical helical spire, or with early glomerate coil.
