dc.descriptionMany thanks go to David Porcel Muñoz and Isabel Sánchez Almazo at the microscopy service of the Centro de Instrumentación Científca (CIC) at Universidad de Granada (Spain), for allowing us to use the optical microscope and for carrying out the SEM analyses, respectively. Many thanks also go to Dr Maria Teresa Galán Puchades (Universidad de Valencia, Spain) for her comments in some of the parasite pictures. Funding for the analyses was provided by the Spanish Ministerio de Economía y Competitividad (MINECO) through the project CGL-2013-42643-P and PID-2019-105546GB-I00. Te fellowship reference BES-2014-070985 of the Program for the Training of Researchers of the MINECO is associated to the project CGL-2013-42643P.es_ES
dc.description.abstractThe 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.es_ES
