Description(s)
Knaust, 2012a:
Unbranched, spheroidal.
Buatois et al., 2017:
Category of architectural design: 2.63. Circular holes and pit-shaped borings.
Mikuláš et al., 1998:
Diagnosis: Borings in those wooden parts of fruits which contain a hollow filled with non-xylic digestible tissue (nuts, stones). The borings consist of a short cylindrical tunnel joining the nut (stone) surface and a natural hollow inside the xylic body.
Comparisons: Lamniporichnus differs from a similar ichnogenus Carporichnus Genise, 1995 by the circumstance that the boring of the former ichnogenus only perforates a wall of the fruit particle. However, in Carporichnus, borings are composed of a longitudinal central cavity and a radial tunnel, both made by the tracemaker (Genise 1995). Similar to identical morphology as Lamniporichnus shows also the ichnogenus Oichnus Bromley, 1981, which, however, differs by its substrate (i.e. shells of marine shally fauna, esp. gastropods and lamellibranchs).
