Abstract
Coprolites of the seal Pachyphoca volkodavi from the Upper Miocene deposits (Kherson) of the Fortepyanka locality (Republic of Adygea) were studied. Two out of five seal coprolites contained a structure resembling fish muscle tissue and included objects with morphology of trematode metacercariae. Obviously, the larvae of the parasite got into the digestive tract of seals from the fish they ate. Microscopic analysis of the coprolites did not reveal helminth eggs, which indicates possible absence of infection.
