Teichichnus rectus Seilacher, 1955

Taxon description

Knaust, 2018a

Remark. T. rectus has been the most common ichnospecies of Teichichnus since the early Cambrian (e.g.Orłowski, 1989; Pacześna, 1996; McIlroy and Brasier, 2017) and has a global record throughout the Phanerozoic (Fig.7,8).Although also known from the Holocene (Wetzel, 1981; Corner and Fjalstad, 1993; Werner, 2002), noconclusion about its trace makers has been reached and producers of several phyla are likely in light of its long age range (Häntzschel, 1975)-

Mikuláš et al., 2013

Irregularly arranged, densely crowded, mutually cross-cutting spreiten-structures resembling troughs filled up in a vertical plane. These are preserved in full reliefs, partly weathered-out, on an upper bedding plane of the sandstone slab. The troughs are straight; preserved parts are 1–7 cm long and ca 4 mm wide. The trace is composed usually of a small number (2–4) of troughs. In vertical plane, all traces probably show a shape of a very broad “U” letter.

Frey & Bromley, 1985

Diagnosis Long, straight, planar to slightly irregular, retrusive spreiten structures oriented at various angles with respect to bedding.

Howard & Frey, 1984

Diagnosis Vertical bladelike spreiten structures consisting of several closely concentric, horizontal or inclined, longitudinally nested individual burrows adjoining single parent tninks; burrows within the spreite are displaced upward (retrusive).
