Iberodactylus Andreui
''Iberodactylus'' is a genus of pterodactyloid pterosaurs belonging to the clade Anhangueria, that during the Early Cretaceous lived in the area of present Spain. The type species is ''Iberodactylus andreui''. History of discovery and naming In the late 1980s, amateur paleontologist Javier Andreu discovered a pterosaur skull at the Los Quiñones site, west of Obón in Aragón. At the time it represented the most complete discovery of pterosaur fossil material in Spain apart from the remains of ''Prejanopterus''. In 2014, the find was reported in the scientific literature by José Antonio Ulloa-Rivas and identified as a member of the Ornithocheiroidea.Ulloa-Rivas, J.A. & Canudo, J.I. 2014.

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...
