North American Eocene sea cows (Mammalia: Sirenia).
Smithson. Contrib. Paleobiol. No. 52: iii + 69. 3 tabs. 34 figs. Sept. 3, 1982.
–Briefly reviews the worldwide Eocene sir. record, and reports in detail on the 22 known New World Eocene localities (1-17). New specimens from Florida (18-39) and North Carolina (39-59) are described, compared with other sirs., and referred to Protosiren sp. New records of Pleistocene Trichechus manatus from the Waccasassa River, Florida (18), and of Protosiren n.sp. from the Late Eocene of Egypt (55-56, 59), are also reported. The primitive sir. dental formula is confirmed to have been 3.1.5.3, and the significance of this for eutherian phylogeny is pointed out (59-60). The pan-Tethyan distribution of Eocene sirs. and its biostratigraphic potential, the possible sequence of sir. adaptive radiations (60-61), and the probable seagrass diet of Eocene sirs. (61-62) are discussed; concludes that the distribution of fossil sirs. is a more reliable guide to the past presence of seagrasses than are the distributions of Foraminifera or other organisms.
