About 5 or 6 miles below Henderson, on Ohio River, many years ago, considerable parts of the skeleton of Megalonyx jeffersonii were found (p. [44]). With them were reported to have been discovered antlers and bones of the deer (p. [234]). A description of the locality was sent to Joseph Leidy and published by him in his work on ground-sloths (Smiths. Contrib. Knowl., vol. VII, art. 5, p. 7). The bone-bed lay at an elevation of only 5 or 6 feet above an ordinary stage of low water. It was composed of a ferruginous sand and contained various species of fresh-water mollusks and stems and limbs of trees. This was underlain by a bluish clay, while above it, rising 40 or 50 feet, were beds of siliceous earth and widely spread marls. Neither the geology of the place, so far as the writer knows, nor the history of the animal requires us to believe that the geological age is beyond that of the Late Wisconsin or Wisconsin. However, a short time before, near Evansville, Indiana, at the mouth of Pigeon Creek, and apparently only about 10 miles away from where Owen found megalonyx bones, there had been discovered by Frances A. Lincke, and described by Leidy (Proc. Acad. Nat. Sci., Phila., vol. VII, 1854, pp. 199–200), a collection of vertebrate fossils. This included remains of megalonyx (p. [32]), a cervical vertebra of a bison (p. [257]), a vertebra of a horse (p. [186]), a tooth of Tapirus haysii (p. [203]), and a part of the upper jaw of the wolf known as Ænocyon dirus (p. [204]). The horse was most probably Equus complicatus, while the bison was probably one of the extinct species. The wolf is regarded as being the same as that so abundantly found in the collections made at Rancho La Brea, near Los Angeles. The writer regards the fauna as belonging to the Sangamon, unless it is still older. The specimens were found sticking out of the river at low water, and it becomes quite probable that the Henderson beds and bones are of the same age as those at Evansville.

As mentioned on another page (p. [223]) it is probable that the fine skull of Platygonus compressus that was sent many years ago to the Academy of Natural Sciences of Philadelphia by Dr. Samuel Brown, of Lexington, Kentucky, and described by Leidy (Trans. Amer. Philos. Soc., vol. X, p. 331, plates XXXV-XXXVII) had been found somewhere in Rock Castle County. It counts as another product of the caves which abound in the Alleghany range of mountains.
