Treatment

Holotype.

SMNS 97028 About SMNS , nearly complete right maxilla with teeth, exposed in occlusal view.

Type locality.

Schumann Quarry, Eschenau, Vellberg municipality, Schwäbisch Hall district, Baden-Württemberg.

Type horizon.

Untere Graue Mergel, Bed E 6, Erfurt Formation, Lower Keuper Subgroup. Age: Middle Triassic (Ladinian: Longobardian).

Referred material.

SMNS 97029 , crushed dentary fragment, preserving part of the mandibular symphysis and part of the right tooth-bearing ramus exposed in occlusal view.

Diagnosis.

Distinguished by the following combination of features: maxillary and dentary teeth with large labial and small lingual cusp linked by labiolingually extending occlusal ridge and by mesial and distal cingula; mesial and distal surfaces of labial cusp each bearing three prominent apicobasal ridges (‘ arrises’); and mandibular symphysis anteroposteriorly wide, edentulous, with thin lateral and anterior edges ( Sues and Schoch 2023).

Comments.

Rutiotomodon tytthos represents the first known Ladinian-age trilophosaurid and the first known representative of this archosauromorph clade from the CEB.
