Bottom Line: The current archeological site is located in northwest of Iran, dated to the Sassanian Era (4(th)/5(th) century CE).In the summer 2012 the carnivore coprolite was obtained within the layers in the mine and were thoroughly analyzed for parasites using TSP rehydration technique.Eggs of 0 were successfully retrieved from the examined coprolite and were confidently identified based on reliable references.

ABSTRACT
Present paper is the second publication introducing the paleoparasitological findings from animal coprolites obtained from archeological site of Chehrabad salt mine in northwestern Iran. The current archeological site is located in northwest of Iran, dated to the Sassanian Era (4(th)/5(th) century CE). In the summer 2012 the carnivore coprolite was obtained within the layers in the mine and were thoroughly analyzed for parasites using TSP rehydration technique. Eggs of 0 were successfully retrieved from the examined coprolite and were confidently identified based on reliable references. Identifying of M. hirudinaceus eggs in paleofeces with clear appearance as demonstrated herein, is much due to appropriate preservation condition has been existed in the salt mine .The present finding could be regarded as the oldest acanthocephalan infection in Iran.

Figure 2: Eggs of M. hirudinaceus retrieved from the coprolite analyzed in this study

Mentions: Out of 170 slides prepared for microscopic study, two acanthocephalan eggs were found. Morphological characters of the eggs such as ovoid shape symmetrically, three-layered shell and an acanthor with the characteristic hooks inside the eggs that measured 82 μm by 51 μm and 84 μm by 51 μm (Fig. 2) led to the diagnosis of the thorny-headed worm, Macracanthorhynchus hirudinaceus. The cited range of the measurments for M. hirudinaceus eggs, 80 μm – 100 μm by 40 μm – 50 μm (13), fits to the eggs found in the coprolites. Polar parts of the outer shell layer were seen partly broken in one (Fig. 2a), while the other one (Fig. 2b) showed the layer more intact.
