Alcyonidiopsis longobardiae Massalongo, 1856
Taksoni kirjeldused
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
