Horaffia kugleri N. Klein & Hagdorn, 2014

Holotype.

MHI 2112 / 5, left humerus.

Type locality.

Schneider Quarry, Obersontheim-Ummenhofen, Schwäbisch Hall district, Baden-Württemberg.

Type horizon.

Grenzbonebed, basal unit of Erfurt Formation, Lower Keuper Subgroup. Age: Middle Triassic (Ladinian: Fassanian).

Referred material.

Four additional humeri: MHI 2112 / 1, left humerus from former Feldner Quarry at Satteldorf-Barenhalden; MHI 2212 / 2, right humerus from Schumann Quarry, Vellberg-Eschenau; MHI 2112 / 3, left humerus from former Härer Quarry at Crailsheim-Tiefenbach; MHI 2112 / 4, right humerus from Schneider Quarry, Obersontheim-Ummenhofen.

Diagnosis.

Distinguished by the following combination of features: very robust, pachyosteosclerotic humerus; proximal head of humerus triangular with protruding preaxial margin and protruding ventral ridge; and distal end of humerus asymmetrical, with preaxially slanted margin (N. Klein and Hagdorn 2014).

Comments.

The distinctive bone histology of these unusual humeri resembles that of Cyamodus (N. Klein and Hagdorn 2014) . Horaffia kugleri is currently known only from isolated humeri. Although it possibly represents a new clade of placodonts its phylogenetic position remains unresolved at present (N. Klein and Hagdorn 2014).
