Delapparentia is a genus of iguanodont dinosaur from the Early Cretaceous period of Galve, Teruel Province, Spain. The type specimen, MPT/I.G, was found in the Spring of 1958 by amateur palaeontologist José María Herrero Marzo. From 25 September 1958 it was collected by Professor Dimas Femández-Galiano, assisted by a Dutch team from the University of Utrecht led by Gustav Heinrich Ralph von Koenigswald. The finds were originally assigned to Iguanodon bernissartensis by Albert-Félix de Lapparent in 1960. In 2006 José Ignacio Ruiz-Omeñaca named it Delapparentia turolensis in a dissertation. Such a nomen ex dissertatione being invalid, he validly named it in 2011. The generic name honours de Lapparent. The specific name is derived from the Latin name of Teruel, Turia.
