    Diagnosis by Kietzmann & Bressan, 2019: Lumbricaria with elongate, bending strings showing overlapping of different parts throughout its length. Cylindrical cross-section. Locally, short segments can appear straight (based on the description emended by Janicke 1970).

     

    Lumbricaria is a trace fossil which is interpreted as the fossilized excrement (coprolite) of cephalopods. This trace genus (Ichnogenus) occurs in the Solnhofen plate limestones and various other similar plate lime occurrences. In the Solnhofen plate limestones, it belongs to the relatively frequent fossils.
