Abstract The fossiliferous beds of Las Hoyas (province ofCuenca, Spain) are composed of limestones (probably Late Hauterivian). The main fossiliferous facies consists of laminated limestone from a lake-basin plain with bottom waters perennially anoxic. The floral and faunal assemblage is similar to that of Montsech (prov. of Lerida, Spain), with divergences especially in the insects and some tetrapods. Bottom-dwelling invertebrates are scarce. Most of invertebrates are arthropods: three crustaceans and a relatively diversified entomofauna. The fishes are the main component of the vertebrate fauna both in number of individuals and diversity (13 different taxa). Among tetrapods the most abundant is a new genus of Caudata. Reptiles are represented by a chelonian, a little lizard and an atoposaurid crocodile. Finally, a new bird is reported from Las Hoyas, with an intermediate phylogenetic position between Archaeopteryx and Ornithurae.

Die Unter-Kreide von Las Hoyas, Cuenca, Spanien

José Luis Sanz; Carmen Diéguez; Francisco José Poyato-Ariza

Die Fossilfundstatte Las Hoyas wurde zu Beginn der 80er Jahre durch den ortlichen Privatsammler Armando Diaz Romeral und den Geologen Santiago Prieto entdeckt (Prieto et Diaz-Romeral 1989). Sie bemerkten Fossilien in Kalkstein-Platten, die zum Bau von Mauern und Fusswegen verwandt wurden. Die ersten Arbeiten im Aufschluss wurden im Sommer 1985 unternommen. Seither sind einige 8000 Fossilien geborgen worden. Zusatzlich zu den Korperfossilien, die in diesem Artikel genannt werden, wurden Spurenfossilien von Invertebraten und Vertebraten gesammelt (Moratalla et Fregenal-Martinez 1995). Das meiste Material, das dem Museo de Cuenca gehort, ist vorlaufig an der Unidad de Paleontologia, Universidad Autonoma de Madrid (UAM) untergebracht.
