“…It is possible this group of parasites emerged during the chronological interval Cambrian -Ordovician (Littlewood andWaeschenbach 2015, Poinar 2015), with arising of the arthopods hosts. however some investigations in the Brazil and other countries identified Acanthocephala eggs only in coprolites of almost 10,000 years old belonging to humans (horne 2002, Gonçalves et al 2003, Fugassa et al 2011, xenarthrans and carnivorous mammals (Ferreira et al 1989, Noronha et al 1994, Sianto et al 2014, Mowlavi et al 2015, Beltrame et al 2016, and birds of prey (Beltrame et al 2015).…”

this study presents the oldest record of Acanthocephala parasite eggs in coprolites preliminary assigned to Crocodyliformes, recovered in the region of Santo Anastácio Municipality, Southwestern São Paulo State. For this, a paleoparasitological investigation was carried out on 53 mineralized coprolites (complete or fragmented), with round shape or cylindrical shape of rounded or pointed ends, 0.2 -3.9 cm in length x 0.1 -2.4 cm in diameter, 3.7 grams in weight, and absence of food remains. Individual samples of the surface and internal portions of each coprolite were extracted by electric drill, dissociated with Cloridic Acid 10% solution, washed with Distilled Water, and filtered in granulometric screen Mesh / Tyler 325. After laboratory processing, the sediments retained on the granulometric screen was studied with Glycerin under optical microscopy, and the presence of four Acanthocephala eggs could be observed in sample of only one of these ichnofossils. All specimens were well preserved and showed 72.5 -85 µm in length x 27.5 -50 µm in width, elliptical shape, three concentric and thick shells, and embryos in their interior. this study inaugurates investigations and knowledge about Paleoparasitology in Crocodyliformes coprolites from the Bauru Group, Upper Cretaceous from the Paraná Basin.

“…In Argentina, these eggs were identified from canid and human coprolites [10, 11]. In Brazil, such eggs were found in feline paleofeces dating back to 9000 years [25]. Cleeland et al by studying DNA extracted from a 1400-year-old desiccated fecal sample from La Cueva de Los Muertos Chiquitos, archeological site in Mexico, identified Physaloptera DNA by amplifying and sequencing an 18S ribosomal RNA gene specific to Ascaris [6].…”

Human spiruridiasis due toPhysalopteraspp. (Nematoda: Physalopteridae) in a grave of the Shahr-e Sukhteh archeological site of the Bronze Age (2800–2500 BC) in Iran

Evidence of rare human helminthiasis in paleoparasitological records is scarce. we report here the finding of Physaloptera spp. eggs in a soil sample collected in the pelvic and sacrum bones area of a skeleton excavated from a grave of Shahr-e Sukhteh archeological site dating back to the Bronze Age. The site is located in southeastern Iran and has attracted the attention of numerous archeological teams owing to its vast expanse and diverse archeological findings since 1997. The spirurid nematodes Physaloptera spp. are rarely the cause of human helminthiasis nowadays, but this infection might not have been so rare in ancient populations such as those in the Shahr-e Sukhteh. Out of 320 skeletons analyzed in this study, only one parasitized individual was detected. This surprising result led us to suspect the role of nematophagous fungi and other taphonomic processes in possible false-negative results. This is the first paleoparasitological study on human remains in this archeological site and the first record of ancient human physalopterosis in the Middle East.

“…DNA analyses are currently being performed to establish a hypothetical membership of family groups. More recently, dating of feline coprolites near a skeleton from this site (Sianto et al 2014) resulted in ages over 6000 years. The age found in this work agrees with findings in this region reported in other studies.…”

This work reports the dating of a fossil human tooth and shell found at the archaeological site Toca do Enoque located in Serra das Confusões National Park (Piauí, Brazil). Many prehistoric paintings have been found at this site. An archaeological excavation unearthed three sepulchers with human skeletons and some shells. Two Brazilian laboratories, in Ribeirão Preto (USP) and Recife (UFPE), independently performed Electron Spin Resonance (ESR) measurements to date the tooth and the shell and obtain the equivalent dose received by each sample. The laboratories determined similar ages for the tooth and the shell (~4.8 kyBP). The results agreed with C-14 dating of the shell and other samples (charcoal) collected in the same sepulcher. Therefore, this work provides a valid inter-comparison of results by two independent ESRdating laboratories and between two dating methods; i.e., C-14 and ESR, showing the validity of ESR dating for this range of ages.
