Diagnosis

Posterior branches of mesethmoid narrow (6, 0> 1); posterior branches of mesethmoid parallel along entire extension (7, 0> 1); fenestra delimited by lateral ethmoid and frontal very large (17, 1> 2); frontal mesial laminar projection absent (23, 1> 0); posterior cranial fontanel very wide and long (27, 1> 3); epiphyseal bar transversely elongate and longitudinally narrow (29, 0> 1); medial groove of cranium absent (30, 0> 1); fenestra delimited by parieto-supraoccipital, pterotic and sphenotic present (34, 0> 1); ventral crest of parieto-supraoccipital process well developed through entire extension of process (48, 0> 1); accessory tooth plates absent (58, 1> 0); optic foramen very reduced (67, 1> 2); ventral tip of subvertebral process spatulate (80, 2> 3); premaxilla narrow and very long, its length two to three times in width (120, 1> 2); ventral crest of hyomandibula absent (142, 0> 1); dorsal crest of urohyal projected anteriorly (156, 0> 1); anterior process of first hypobranchial inconspicuous (173, 1> 0); second hypobranchial transversely elongate, its mesial face acute (176, 0> 1); distal portion of uncinate process of third epibranchial acute (183, 1> 0); posterior margins of fourth epibranchial slightly convex, one-fourth as wide as long (187, 0> 1); median crest associated with neural spine of third vertebra very high (201, 0> 1); accessory crest connecting transverse and median crests associated with neural spine of fourth vertebra present (204, 0> 1); general aspect of superficial ventral ossification regularly arched (211, 0> 1); posterior process of cleithrum very short (224, 1> 0).

Ambiguous optimization: Frontal as main component of bony bridge formed by lateral ethmoid and frontal (15, 0> 2); third basibranchial hourglass shaped (168, 1> 0); transverse crest associated with neural spine of fourth vertebra low (200, 1> 0).
