Here, a coprolite (fossilized feces) from the 1.2-million-year-old paleontological site of Haro River Quarry in northwestern Pakistan was analyzed for paleoparasites. Micromorphological thin sectioning and Fourier-Transform Infrared Spectrometry (FTIR) analysis confirms the coprolite belonged to a bone-eating carnivore, likely the extinct giant short-faced hyena (Pachycrocuta brevirostris). Parasitological analysis shows the coprolite to be positive for Toxocara sp. To our knowledge, this is the earliest evidence for Toxocara sp. found.}}, journal = {{Journal of Parasitology}}, volume = {103}, number = {1}, pages = {138--141}, }
