Cymatosaurus erikae Maisch, 2014

Holotype.

SMNS 10977 , partial cranium (Fig. 8 B ).

Type locality.

Jenzig near Jena, Thuringia.

Type horizon.

Röt Subformation 4, Röt Formation, Upper Buntsandstein Subgroup. Age: Middle Triassic (Anisian: Aegean).

Diagnosis.

Distinguished by the following combination of features: estimated skull length about 20 cm; nasals not reaching external nares or anterior orbital margins; frontal not entering orbital margin; frontal closely approaching but not entering supratemporal fenestra; at least two maxillary teeth anterior to fangs; parietals extending up to posterior orbital margins, posteriorly narrow, and lacking sagittal crest; vomers unfused; palatines narrow and elongate; and quadrates and quadrate condyles inclined ( Maisch 2014).

Comments.

Rieppel (1997) referred SMNS 10977 to Cymatosaurus latifrons , but Maisch (2014) argued for its specific separation.
