Publisher's Synopsis
Excerpt from A New Fossil Cetacean
Of primitive cetaceans whose skull characters are sufficiently known to admit Of comparison with Archaeodelphis, three genera stand out as bearing a considerable degree Of similarity to it, namely, Agoro phius, Prosqualodon, and Patriocetus. The first Of these, with the single species A. Pygmaeus, is still known from the type-specimen only now lost the history and peculiarities Of which have been fully set forth by True Although the intermaxillaries and nasals as well as most Of the inferior side of the cranium Of this speci men were not preserved, still it bears Obviously a general superficial resemblance to Archaeodelphis in the somewhat ?attened profile, the great anteroposterior extent and the breadth Of the temporal fossae, and the resulting narrowness Of the region separating the two fossae anteriorly. This narrow isthmus in both genera, is formed dorsally by the parietals which instead Of being excluded from the peak of the cranium as in modern cetaceans, meet behind the frontals at the dorsal line. Further points Of resemblance are found in the shape Of the brain-case and in the great lateral extent Of the orbital portion Of the frontal with its well-developed and tapering postorbital process.
