FIGURE 2. Paleogeographic map of Western Europe during the early Eocene (modified from Marandat et al., 2012) and situation of the Catalan localities yielding material described in the text and other contemporaneous European fossil sites. Note that the localities of the Southern Pyrenean Basin (Escarlà, La Roca, Masia de l’Hereuet, Barranc del Fusteró and Font del Torricó) are geographically very close, although situated in different sub-basins (see text).

FIGURE 3. Distribution of lizard and amphisbaenian taxa from the latest Cretaceous to the late Eocene in the Iberian Peninsula. Records from Font del Torricó are omitted because its exact age inside the early Eocene is unknown. Black squares indicate unambiguous records, whereas grey squares indicate uncertainty. LaMa: Late Maastrichtian; eLaMa: earliest Late Maastrichtian; E/LaMa: Early or Late Maastrichtian; Late Campanian.
