The bones of man belonged to the skull and are as completely fossilized as the bones of a horse and are wholly free from organic matter.
Among the mammals of this list there are no genera and few species that have not been found in the Pleistocene at many places in the United States. The presence of Elephas imperator and three species of Equus and Chlamytherium apparently indicate Pleistocene of about Aftonian times.
From Palma Sola, Manatee County, there have been sent to the U. S. National Museum by Mr. Charles T. Earle many specimens of fossil vertebrates, found at various times washed up on the beach. Some belonged evidently to deposits older than the Pleistocene, probably to Miocene, and included teeth of sharks, a beak of a platanistid porpoise, and a lower tooth of a sirenian, Metaxytherium floridanum. Other specimens, as bones of a camel, parts of the shells of tortoises, alligator or crocodile teeth and bones are of uncertain age. Ten species of the list are referred to the Pleistocene. All of the teeth are isolated, but many are well preserved and little water-worn. The bones are mostly fragmentary, some worn, some not.
Polk County.—On page [159] is an account of a tooth of an elephant. Elephas columbi, reported as being found at Kingsford, Polk County, under 19 feet of phosphate rock and sand. It may belong to E. imperator. On page [196] is detailed the finding of several teeth of Equus in the phosphate mines of Kingsford. The species E. leidyi and E. littoralis are recognized. Unless these elephant and horse-teeth had been incorrectly reported or had been secondarily introduced into the phosphate beds, they are, in the writer’s opinion, to be referred to the first glacial stage, the Nebraskan. Dr. W. H. Dall has somewhere reported the finding of tusks at Bartow; these were supposed to have belonged to Elephas columbi (p. [180]). At Nichols the large land-tortoise Testudo hayi Sellards has been recovered from a phosphate mine. From phosphate mines at Brewster has been secured the following list of vertebrates, obtained from Dr. Sellards’s reports (Florida Geol. Surv., vol. VII, pp. 100, 106, 108; vol. VIII, pp. 95, 96, 98, 100).
- Gomphotherium floridanum? (p. [123]).
- Mammut progenium (p. [123]).
- Hipparion minor (p. [197]).
- Procamelus minor?
- Teleoceras or Aphelops sp. indet. (p. [211]).
- Agriotherium schneideri.
- Tomistoma americanum.
All of this list are referred by Sellards to the upper Miocene or lower Pliocene. The writer regards them as belonging to the first stage of the Pleistocene.
From a phosphate pit at Christina, Sellards (Florida Geol. Surv., vol. VII, p. 106, fig. 35) has reported a tooth of an undetermined species of Gomphotherium.
