1923Vorläufige Notiz über die Pachyostose und Osteosklerose einiger mariner Wirbeltiere.
Anat. Anz. 56(15/16): 353-359. Feb. 26, 1923.
—Discusses pachyostosis and related physiological phenomena with reference to adaptation to air-breathing and submergence in sirs. and other marine vertebrates. Concludes that heavy bones serve as ballast, at least in earlier stages of aquatic adaptation, but that pachyostosis and osteosclerosis are basically disturbances of function that might in some cases bring about extinction.
