However, Hampe (1992) justifies its provisional inclusion of the specimen in the genus Kronosaurus based on the large size of the skeleton, the short neck with 12 vertebrae, the expanded opisthotic, the small and unpaired supraoccipital, and the cervical rib facets extending through the entire length of the centra.
En vista lateral, la curvatura frontal es poco pronunciada, incluso se muestra casi recta en algunos especimenes; la cresta sagital y supraoccipital son desarrolladas en diferente grado, en general los machos lo tienen ligeramente mas desarrollados que las hembras; las alas del pterigoides son delgadas, muy alargadas y dirigidas posteriormente; el condilo occipital esta bien desarrollado.

Rough scales with many small ctenii covering most of body; head, including jaws, completely scaled, scales on cranium between supraoccipital crest and snout minute and unorganized, these scales also cover jaws, circumorbital area, and region ventral to orbit; preopercle and opercle covered in loosely organized rows of larger scales, posteriorly flanked by accessory scales.
[5, 6] This indicates that the bone developing from middle and upper pairs of nuclei was part of parietal bone in early mammalian phylogeny and it has now come to join the occipital bone in primates and man.[1] Further, the intermediate segment which lies between the superior and highest nuchal lines remains fused with supraoccipital part of occipital bone.

At birth the Kerckring center was identified as an ossicle completely separated from the supraoccipital bone in 132 newborns (66%).
Diagnosis: A Bison with relatively high and narrow occipital region; frontals flat; parietals relatively well developed on the roof of brain-case; temporal fossae very narrow at their hinder ends, which are directed upward and inward, and indent the supraoccipital more deeply than in most other known species of Bison; horncores relatively long, and curving upward and farward, anteroposteriorly compressed, cross-section with flat anterior surface, so that the anterior and inner keels, though well rounded, are distinguishable, posterior keel not indicated.
It is the result of the incomplete ossification of the ventromedial part of the supraoccipital bone, (PARKER & PARK, 1974a; DE LAHUNTA, 1983; WATSON et al., 1989).
Identifications of species were based on morphological criteria available in the literature and included presence of epidermal villi, depth of caudal-fin fork, contact between supraoccipital and supraneural bones, basal length of anal fin in relation to length of head, profile of distal margin of anal fin, basal length of anal fin, number of anal-fin rays, length of dorsal spine, and number of gill rakers (Rutter, 1896; Minckley, 1973; Lundberg, 1992; Miller et al., 2005).
