The late Campanian-early Maastrichtian site of Lo Hueco (Cuenca,
Spain) has provided a set of well-preserved crocodyliform skull and
lower jaw remains, which are described here and assigned to a new
basal eusuchian taxon, Lohuecosuchus megadontos gen. et sp. nov. The
reevaluation of a complete skull from the synchronous site of
Fox-Amphoux (Department of Var, France) allows us to define a second
species of this new genus. Phylogenetic analysis placesLohuecosuchus
in a clade exclusively composed by European Late Cretaceous taxa. This
new clade, defined here as Allodaposuchidae, is recognized as the
sister group of Hylaeochampsidae, also comprised of European
Cretaceous forms. Allodaposuchidae and Hylaeochampsidae are grouped in
a clade identified as the sister group of Crocodylia, the only
crocodyliform lineage that reaches our days. Allodaposuchidae shows a
vicariant distribution pattern in the European Late Cretaceous
archipelago, with several Ibero-Armorican forms more closely related
to each other than with to Romanian Allodaposuchus precedens.
