Alcyonidiopsis longobardiae Massalongo, 1856

Taxon description

Fan, R. et al., 2021

Horizontal, straight to winding, cylindrical burrows with numerous relatively small pellets 0.3–0.5 mm in diameter. The burrow is 2–3 mm wide. Cross-cutting relationship between individuals is common, locally showing dense overlapping. Preserved as full relief in thin-bedded limestone of the Sandbian.

Emended diagnosis after Chamberlain. Linear and sinuous inclined and horizontal burrows, seldom branching and filled with relatively small ovoid pellets. http://www.ichnopolis.dk/html/alcyonidiopsis.html
