Diagnosis
ReferenceDiagnosis
M. D. Uhen et al. 2008Praekogia differs from the Recent species of Kogia by having dense rather than spongy cranial bone; lower cranial crests; orbit situated anterior to the end of the zygomatic process of the squamosal, not posteriorly within the temporal fossa; small skull, slightly more than one half the size of that of adult Kogia breviceps; cranium less foreshortened than in Kogia; lateral maxillary crests high and with sharp margins, not rounded and inflated, forming nearly straight lateral margins of the supracranial basin; left premaxilla wraps around the posterior side of the left naris and contributes to a sagittal facial crest in the supracranial basin that is less developed than in Kogia; the right margin of the right premaxilla does not form a Kogia-like crest but has a deep fossa; temporal fossa is large; lateral surface of jugal is very slender (Barnes, 1973).
