Description

Fro his sfudy on the variation in the teeth of Desmostylus, comparing them with that of the human teeth, the author finds that they show a tendency of degeneration, and concludes., That Desmostylus is a degenerate mammal., It is therefore inferred that the geological distribution of Desmostylus is limited to a narrow range of time (Middle Miocene)., This inference has been confirmed by stratigraphic studies.,
