Coprolites of the hyena Pachycrocuta brevirostris from the Lower Pleistocene (Upper Villafranchian) of Taurida Cave (Crimea) were studied. One of the three hyena coprolites contained eggs of a helminth. These eggs were attributed to Toxocara sp. based on size and morphology. Toxocariasis was evidently a very common infestation among extinct hyena species. The find of toxocara in P. brevirostris coprolite from the Taurida Cave is the earliest evidence of roundworm infestation in P. brevirostris.
