       Notosuchus was named in‭ ‬1896‭ ‬and was the first of what would become known as the notosuchian crocodiles that would be described to science.‭ ‬Attaining sizes up to one and a half meters in length,‭ ‬Notosuchus was small when compared to most other crocodiles,‭ ‬though itself still larger than most known notosuchian genera.‭ ‬Notosuchus was also one of the first crocodiles confirmed as being mostly if not entirely terrestrial.‭ ‬This means that Notosuchus spent most of their time roaming about on dry land,‭ ‬only approaching water to drink.
       One of the most startling discoveries concerning Notosuchus came in‭ ‬2008‭ ‬when a much more complete skull preserving a higher level of detail was discovered.‭ ‬The describers of this study‭ (‬Fiorelli‭ & ‬Calvo‭) ‬showed that not only did the skull lack a bony nasal septum,‭ ‬but it was quite likely that a short muscular trunk probably grew from the end of the snout.‭ ‬The lower jaw also supported the placement of a fleshy lower lip that would have worked in conjunction with the short trunk to grip things.‭ ‬It is also possible that Notosuchus may have also had a fleshy cheek to prevent food from falling out of the sides of the mouth when being chewed.‭ ‬It now seems that Notosuchus would have lived like a modern day‭ ‬wild‭ ‬pig,‭ ‬sniffing through the undergrowth and leaf litter,‭ ‬using smell to identify food that was otherwise hidden from other animals.
