Mahajangasuchidae is an extinct family of neosuchian crocodyliforms. It currently contains two genera, Mahajangasuchus and Kaprosuchus, both of which lived during the Late Cretaceous in Gondwana. It is defined as the most inclusive clade containing Mahajangasuchus insignis but not Notosuchus terrestris, Simosuchus clarki, Araripesuchus gomesii, Baurusuchus pachecoi, Peirosaurus torminni, Goniopholis crassidens, Pholidosaurus schaumbergensis, or Crocodylus niloticus.[1] Phyogenetically, Mahajangasuchidae is placed just outside pholidosaurids and more derived neosuchians.
Defining characters of the family include fused nasals, a jaw articulation below the posterior maxillary tooth row, a deep mandibular symphysis that is oriented anterodorsally, and the formation of a hornlike posterodorsal process from the squamosal and parietal (which is much more pronounced in Kaprosuchus).
