Notosuchians
Notosuchia is a clade of primarily Gondwanan mesoeucrocodylian Crocodylomorpha, crocodylomorphs that lived during the Jurassic and Cretaceous. Some phylogeny, phylogenies recover Sebecosuchia as a clade within Notosuchia, others as a sister group (see #Phylogeny, below); if Sebecosuchia is included within Notosuchia its existence is pushed into the Late Miocene or Zanclean, Early Pliocene, about 7 to 4.5 million years ago. Fossils have been found from South America, Africa, Asia, and Europe. Notosuchia was a clade of terrestrial crocodilians that evolved a range of feeding behaviours, including herbivory (''Chimaerasuchus''), omnivory (''Simosuchus''), and terrestrial hypercarnivory (''Baurusuchus''). It included many members with highly derived traits unusual for crocodylomorphs, including Mammal, mammal-like teeth, flexible bands of shield-like body armor similar to those of armadillos (''Armadillosuchus''), and possibly fleshy cheeks and Pig, pig-like snouts (''Notosuchus'').

Mahajangasuchidae
Mahajangasuchidae is an extinct family (biology), family of notosuchian 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, Notosuchus terrestris'', ''Simosuchus, Simosuchus clarki'', ''Araripesuchus, Araripesuchus gomesii'', ''Baurusuchus, Baurusuchus pachecoi'', ''Peirosaurus, Peirosaurus torminni'', ''Goniopholis, Goniopholis crassidens'', ''Pholidosaurus, Pholidosaurus schaumbergensis'', or ''Crocodylus niloticus''. Phylogenetically, Mahajangasuchidae is placed just outside Pholidosauridae, pholidosaurids and more derived neosuchians. Defining characters of the family include fused nasal bone, 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 fro ...
