Hydrostasis in the Sirenia: quantitative data and functional interpretations.
Mar. Mamm. Sci. 7(4): 331-368. 5 tabs. 18 figs. https://doi.org/10.1111/j.1748-7692.1991.tb00111.x Oct. 1991.
–Analyzes the distribution of skeletal mass in T. m. latirostris and the positions of the centers of gravity and buoyancy in T. inunguis, concluding that increased volume and density of bones (= "pachyosteosclerosis", a term introduced here) do indeed serve in sirs. as ballast to maintain horizontal trim and neutral buoyancy. The design and position of the lungs also seem to serve this purpose. Selection for maintenance of trim and maximization of turning moments of the flippers may help account, respectively, for loss of hind limbs and shortening of the neck. The gross anatomy of a sir. (T. inunguis) is illustrated in serial cross sections for the first time. Summarizes the distribution of pachyosteosclerosis in various fossil sirs., and concludes that this condition is fully adaptive and in no sense "pathological".
