This paper describes the skull of the eusuchian Allodaposuchus
subjuniperus sp. nov. This new skull was recovered between the
villages of Beranuy and Serraduy del Pon (Huesca, Spain).
Stratigraphically, it was located in a level of coarse-grained
sandstones in the middle-upper part of the lower red unit (Conqués
Formation) of the Tremp Group, in the uppermost Maastrichtian close to
the Cretaceous–Paleogene boundary. Until now Allodaposuchus was a
monospecific genus. Phylogenetic analysis places the new taxon as a
basal member of Eusuchia forming a clade with the other European
Allodaposuchus remains and as a sister clade to the endemic European
members of Hylaeochampsidae. Furthermore, Allodaposuchus and
Hylaeochampsidae are within the stem of Crocodylia, being key taxa to
understanding the origin of Crocodylia. The new taxon is the latest
record of Allodaposuchus from Europe, and it presents significant
enough morphological differences from Allodaposuchus precedens to
establish a new species. The morphological variations in the material
included in Allodaposuchus, the wide range of age and the geographical
separation among the remains from Romania, France and Spain indicate
that Allodaposuchus is not a monospecific genus as traditionally
established.
