Updating titanosaurian diversity (Sauropoda) from the Late Cretaceous
of Spain: the fossil sites of Laño and Chera.
Spanish Journal of Paleontology 30(2): 293-306

Three titanosaurian sauropods are well-known from the
Campanian-Maastrichtian of the Ibero-Armorican Island (southwestern
Europe): Lirainosaurus astibiae from Spain, and Ampelosaurus atacis
and Atsinganosaurus velauciensis from France. However, a higher
titanosaurian diversity has been suggested for this island, a
hypothesis that has gained traction in recent years as a result of new
discoveries in fossil sites from Spain and southern France. An
estimation of the titanosaurian diversity in the late Campanian-early
Maastrichtian of the Iberian Peninsula is made here on the basis of
the available information from the three fossil sites that have
yielded the best preserved fossil remains: Laño (Condado de Treviño),
Chera (Valencia), and Lo Hueco (Cuenca). The results confirm the
hypothesis of a higher titanosaurian diversity in the Iberian
Peninsula: from one to, at least, three taxa. Moreover, we also
suggest the presence of two different titanosaurian morphotypes in the
site of Chera, with one of them representing Lirainosaurus.
