Description
Notosuchians were generally small, with slender bodies and erect limbs. The most distinctive characteristics are usually seen in the skull. Notosuchian skulls are generally short and deep. While most are relatively narrow, some are very broad. Simosuchus has a broadened skull and jaw that resembles a pug, while Anatosuchus has a broad, flat snout like that of a duck.
The teeth vary greatly between different genera. Many have

This cladogram represents the results of the most comprehensive analysis of notosuchian relationships to date, performed in the description of Antaeusuchus taouzensis by Nicholl et al. 2021. It is largely based on the matrix from the above Pol et al. 2014 study, but also adding character scores from Leardi et al. 2015, Fiorelli et al. 2016, Leardi et al. 2018, and Martinez et al. 2018. The final matrix consisted of 121 taxa scored for 443 morphological traits.[8]
