Description(s)
Taylor & Wilson, 2003:
Remark: Narrow curved, branching tunnels connected to the surface by apertures. Attributed to colonial species of phoronid worms.
Knaust, 2012a:
Branched, network.
Buatois et al., 2017:
Category of architectural design: 2.68. Branched tubular borings.
Stiller, 2005:
Several different groups of organisms such as sponges, annelids, various other "worms", bryozoans, or "protists" have been supposed to be the producers of Talpina borings (e. g. Voigt, 1972, 1975) . The overall shape of Talpina borings shows features typical for organisms that live in colonies. Voigt ( 1972, 1975) showed that Talpina borings very closely resemble the borings of pseudocolonies of the Recent phoronid Phoronis ovalis Wright, 1856 in molluscan shells, and that the ichnogenus Talpina, therefore, with great certainty represents borings produced by pseudocolonial phoronids.
Gaaloul et al., 2023:
Emended diagnosis.—Narrow, tubular borings in lithic or hard skeletal substrates, forming multi-branching tunnel systems with apertures towards the exterior. Tunnels with circular to oval cross-section, straight to strongly curved; short side branches towards apertures often developed near branching points of the main tunnel system. Tunnels may anstomose
