We report on new mosasaurid remains, namely isolated teeth, from the Upper Maastrichtian shallow marine environment of Albaina in the Laño quarry (Condado de Treviño). The new specimens belong mostly to mosasaurines, i.e., Mosasaurus hoffmanni, Prognathodon solvayi, Prognathodon sectorius, and to the russellosaurine plioplatecarpine Platecarpus cf. ictericus. Prognathodon solvayi and Platecarpus cf. ictericus were previously known from Albaina. This is the first mention in the site of Mosasaurus hoffmanni, widespread in Maastrichtian outcrops located around palaeolatidude 30-40°N, from New Jersey (USA) to Turkey passing through Europe where it is commonly found. Prognathodon sectorius has a comparable palaeobiogeographical distribution, though not so expanded, that M. hoffmanni, being known in the Maastrichtian of New Jersey (USA) and Europe and, since recently, in the Campanian of Navarre. With six different taxa reported here, Albaina is the richest outcrop in specifi c mosasaurid diversity from the Maastrichtian of southern Europe. © Sociedad Española de Paleontología ISSN 2255-0550.

We report here on new vertebrate fossils from the latest Cretaceous of Albaina (Laño quarry, Condado de Treviño), northern Iberian Peninsula. They consist of an incomplete hadrosauroid femur and two partial plates of turtles, one belonging to a Pleurodira (Bothremydidae), the other one to an indeterminate taxon, probably corresponding to a Pan-Cryptodira. They are the first dinosaur and turtle remains found in the Late Maastrichtian sublittoral beds of Albaina. Other components of this shallow marine vertebrate fauna are selachians (sharks, rays), actinopterygians (pycnodonts, teleosts) and marine reptiles (mosasaurids, plesiosaurs). The Albaina femur is one of the few hadrosauroid remains from the Late Maastrichtian of Europe found in marine environments, and the first one described from this kind of deposits in the Iberian Peninsula. The histological structure of the bone indicates that it belongs to an immature individual of small size. © 2015 Académie des sciences.

In recent years, the discovery of isolated teeth from the Late Cretaceous (Campanian-Maastrichtian) of the Basque-Cantabrian Region, in the north of the Iberian Peninsula, has permitted to recognise at least four different mosasaurid taxa in several sites of Alava and Condado de Treviño: Mosasaurus leinonnieri, Prognathodon solvayi, Platecarpus cf. icrericus and Tylosaurus sp. A new specimen, which consists of a fragment of skull with articulated portions of the maxilla and prefrontal, from the Campanian of Navarre is described here. This material is assigned to Prognathodon cf. sectorius on the basis of dental features. It constitutes the only cranial remain and the most significant mosasaurid fragment known to date in the Iberian Peninula. P. sectorius was previously recorded from the Maastrichtian of New-Jersey and The Netherlands.
