“…Because of the paucity of the Iberian Paleocene record, early Eocene assemblages like those described herein provide the best chances for evaluating the recovery of faunas after the K/Pg extinction, but mainly record a migratory event where many taxa from other continents (North America and possibly Asia and/or Africa) joined the poorly diverse Paleocene taxa in Europe. Moreover, the Late Cretaceous Iberian record is also limited, with just a few localities presenting some lizard diversity (Rage, 1999;Blain et al, 2010;Pereda-Suberbiola et al, 2015;Blanco et al, 2016) and always yielding fragmentary material. Such a poor record of lizard assemblages around the K/Pg boundary strongly contrasts with the wellknown assemblages from the Late Jurassic (Seiffert, 1973;Broschinski, 2000) and Early Cretaceous (Evans and Barbadillo, 1997, 1998, 1999Bolet and Evans, 2010b, 2012bEvans and Bolet, 2016), yielding much better preserved specimens and more diverse assemblages.…”
