Diagnosis
ReferenceDiagnosis
P. Penkalski 2018Squamosal horns large and keeled, with incipient recurvature but not as horn-like as in O. horneri; eight vertebrae in synsacrum (4-2-2, plus cd1); neural spines tall; caudal neural spines erect; proximal caudal neural spines curved cranially; large (28 cm), high osteoderm that is weakly mammillary, keeled cranially, and ribbed, with an open subconical apex; otherwise as for genus. Differs from S. cutleri in having a smaller nuzzling plate, only eight vertebrae in the synsacrum, slightly less constricted swellings between dorsosacral centra, several osteoderm shapes with no counterparts in S. cutleri, more strongly keeled proximal caudal osteoderms, and more pronounced radial ribbing or fluting on some of its postcervical osteoderms.
