A. Hastings et al. 2010 | As for type species: "Shorter snout, approximately 54–59% of the dor- sal skull length, than that of all other known dyrosaurids. Also differs from all other dyrosaurids in having approxi- matly 11 teeth in each maxillary, 8 of which are anterior to the orbits. Further differs from all known dyrosaurids ex- cept Chenanisuchus in having a wide interfenestral bar that is square-shaped in cross-section. Further differs from all other dyrosaurids except Phosphatosaurus (and possibly Aram- bourgisuchus) in having a reduced fourth premaxillary tooth. Further differs from Phosphatosaurus and Sokotosuchus in lacking a ‘festooned’ lateral margin of the snout in dorsal view. Further differs from Hyposaurus, Rhabdognathus, Atlanto- suchus, and Guarinisuchus in having a mediolaterally straight posterodorsal margin of the parietal. Further differs from Chenanisuchus and Sokotosuchus in having well-developed oc- cipital tuberosities. Further differs from Chenanisuchus in hav- ing ornamentation continuous across dorsal and lateral surfaces with no interruption across sutures and orbits medially and dor- sally placed, most closely approximating the orbit position of Dyrosaurus. Further differs from Hyposaurus rogersii in having teeth with straight, rather than twisted anterior carinae." Hastings et al. (2010): 141 |
