Phycodes circinatum Richter, 1853

Taxon description

Seilacher, 2000a

Emended diagnosis: preserved as positive hyporelief on soles of thin silt beds. Tightly packed bundles of retrusive spreite bodies and curve back distally in a palmate faschion. Delicate transverse corrugation has been observed in a few spesimens. Because distal ends merge into the overlying silt bed, it is not clear wether the generating tube (2-3mm in diameter) was J- or U- shaped.
