Urohelminthoida Sacco 1888

DESCRIPTION: Trace fossil preserved usually as string-sized, deep hypichnial meanders. Lateral appendages protrude outwardly from the curved segments of the meanders. The lateral appendages which pass straight into one arm of the meanders, but form an angle with the second arm are the most pronounced feature of this ichnotaxon, approximately 60 mm long. The distance between meanders varies from tight to widely spaced (cf. Uchman, 1995).

BEHAVIOR(S): Fodinichia (grazing, farming)

ENVIRONMENTAL SETTINGS: Deep marine flysch deposits, Mesozoic shallow marine deposits.

POSSIBLE TRACEMAKERS: Marine organisms such as annelid worms

GEOLOGIC RANGE: Jurassic-recent, questionable forms occur in the Ordovician (Zagora 1997)

REMARKS: One of the Graphoglyptids found in the soles of turbidites.
