abstract = {The exceptional fossil site of Las Hoyas (upper Barremian, Cuenca, Spain) yields abundant small
to medium vertebrate coprolites, hindering the search for parasites. We studied the contents of
29 coprolites that were previously classifed into distinct morphotypes. Several parasitic eggs
were retrieved from two of these coprolites, confrming the second record of digenea trematode
eggs and nematode (ascaridid) eggs from an Early Cretaceous locality. The cylindrical coprolite
containing anisakid eggs was likely produced by a crocodylomorph as the parasite host, whereas
the bump-headed lace coprolite indicates the role of a fsh as an intermediary or defnitive host of
the trematodes and ascaridids. These trace and body fossils show that the Las Hoyas 126–129 Ma
lacustrine ecosystem documents the early connection between basal Gonorynchiformes fsh and
digenetic trematodes.},
