Multina Orłowski, 1968

Remarks. Multina Orlowski, 1968 as well as Pseudopaleodictyon Pfeiffer, 1968 display overcrossings at the different levels; this feature distinguishes these ichnogenera from Protopaleodictyon Ksizkiewicz, 1958 (Uchman, 1998). According to Or³owski and Zyliñska (1996), Multina in its type material differs from Megagrapton Ksizkiewicz, 1968 in its occurrence at the tops of beds and by less regular nets. However, other specimens ascribed to this ichnogenus can be preserved in different parts of the bed. Multina is interpreted as a structure, formed by feeding organisms or searching for food (e.g., Buatois and Mángano, 2004). More details on the taxonomy and ethology of Multina are presented by Uchman (1998, 2001) and Buatois et al. (2012).

This is an endichnial, horizontal, irregular net, of which meshes are formed by branching strings, which are 1–2 mm in diameter. The strings display arcuate to slightly winding courses and can miss other strings on slightly different levels. The meshes are from 6 to 22 mm, exceptionally 60 mm in the maximal width. The net runs along laminae in sandstone beds.

Multina is characterized by overcrossings of strings, also at different levels, in very irregular polygons (Uchman, 1998).

Irregular overlapping networks having straight, meandering to winding strings. Network size is 28.1–190.4 mm and string diameter is 2.0–4.0 mm. Preserved in full relief on sandstone bases.
