Massaliasuchus is an extinct monospecific genus of allodaposuchid eusuchian crocodyliform that is known from fossils found in SantonianCampanian-age Upper Cretaceous rocks of southeastern France.[1]

Systematics

[edit]

Massaliasuchus was first described in 1869 by Philippe Matheron as Crocodilus affuvelensis, based on remains including skull bones.[2] The new genus name was given to it in 2008 by Jeremy Martin and Eric Buffetaut. Massaliasuchus was considered to be related to early alligatoroids. Its name means "Marseille crocodile".[1]

Recent cladistic analysis places Massaliasuchus as a member of Allodaposuchidae, a clade of basal eusuchians from the Late Cretaceous of southern Europe.[3] The genus can be distinguished from Musturzabalsuchus in having 15 alveoli in the dentary.[4] However, Massaliasuchus is usually omitted from phylogenetic analyses since it is only represented by poorly-preserved material.[5]
