Description
Spreiten-bauten formed by series of long horizontal burrows stacked vertical to bedding; resembling stacked flat U-shaped roof gutters with pipe at top; wall-shaped laminar body straight or slightly sinuous; generally not branching; commonly retrusive built but can also be protrusive, up to about 50 cm long (in M.Cam. of Öland up to 135 cm), about 10 cm or more in height. [Endogenic burrows, belonging to fodiniehnia; producer unknown, but, due to the very long time range of this ichnogenus, certainly made by different groups of animals; comparable modern structures made by the Recent polychaete Nerds diversicolor (see SEILACHER, 1957, p. 203); MARTINSSON (1965, p. 216) explained Cambrian specimens as combinations of retrusive and protrusive digging activity; transitional forms to Rhizocorallium (L.Carb., Scotland) were described by CHISHOLM (1970b); as shown by SELLWOOD (1970, p. 494), a limb of a vertically retrusive Rhizocorallium may be mistaken for Teichichnus; tunnels of Ophiomorpha have been observed to grade into Teichichnus-like structures (Eoc., N.Am., Miss.) (Hester & Pryor, 1972, p. 686); the relationships of Teichichnus to Phycodes were discussed by HANTZSCHEL & REINECK (1968, p. 26).]
