Ubinia Grossheim 1961

DESCRIPTION: Trace fossils preserved as a hypichnial, straight or slightly winding, axial string with arcuate or straight simple branches. Ubinia has a zigzag-shaped axial part and the branches alternate on either side along the length of the central axis (after Wetzel & Uchman, 1997).

BEHAVIOR(S): Fodichnia

ENVIRONMENTAL SETTINGS: Fully marine flysch deposits

POSSIBLE TRACEMAKERS: Marine worms?

GEOLOGIC RANGE: Devonian-Paleocene

REMARKS: Ubinia Grossheim was revised by Wetzel & Uchman, 1997. Graphoglyptids, "gardening" and "trapping" burrows (sensu Seilacher, 1977), such as Paleodictyon and Ubinia are representative of low to intermediate benthic food levels. The occurrence of patterned feeding burrows and deep- layer colonizers indicates that benthic food was available below the layer inhabited by graphoglyptid producers.
