Diagnosis
ReferenceDiagnosis
M. D. Uhen et al. 2008Small to medium-sized sperm whale having twenty teeth in each upper jaw (17 in maxilla; 3 in premaxilla). Dentine core of slender curved teeth often with open funnel-like pulp cavity; fine annular lines of growth and longitudinal fluting characterized the dentine core of larger teeth; outer layer of cementum may completely cover the dentine on undamaged teeth; conical tip or crown of teeth occasionally black and polished, but lacks enamel; no perceptible distinction between crown and root or visible constriction to form neck below crown. Vertex of cranium with large supracranial basin bounded laterally on right side by elevated border of right maxillary; on left side by left premaxillary and elevated crest of underlying left maxillary; and posteriorly by posterior borders of both maxillae which override medially the posterior ends of the frontals and abut against the dorsal crest of the supraoccipital. Right nasal bone either lost or greatly reduced; the left nasal bone flattened against the frontal behind greatly enlarged left nasal passage and partially concealed by squamous overlap of markedly expanded posterior portion of right premaxillary (Kellogg, 1965).
