2. _Millersburg, Holmes County._—In the University of Ohio there is a mounted specimen of _Megalonyx jeffersonii_ containing a considerable part of the skeleton; the missing portions are replaced artificially. The remains were found in the eastern part of Holmes County just north of the terminal moraine of the Wisconsin drift-sheet. This moraine had led to the formation of a marsh, and in this the animal ended his life. The place was said by Orton to be 6 miles east and a mile north of Millersburg. The skeleton lay on shell marl beneath 6 feet of peat. The remains have been described by Claypole (Amer. Geologist, vol. VII, 1891, pp. 122–132, 149–153) and by Hay (Geol. Surv. Indiana, vol. XXXVI, 1913, p. 558; Geol. Surv. Iowa, vol. XXIII, 1914, p. 110).
The only member of the order of Xenarthra that has yet been found in this State is _Megalonyx jeffersonii_, and this in only one place, viz, Evansville.
1. _Evansville, Vanderburg County._—In 1854 (Proc. Acad. Nat. Sci. Phila., vol. VII, pp. 199–200), Leidy described a collection of vertebrate fossils secured by Mr. Francis A. Lincke from the banks of the Ohio River, near the mouth of Pigeon Creek, a short distance below Evansville. At that time and locality bones were usually found sticking out of the bank when the water in the river was low. The bones sent to Leidy were thoroughly impregnated with oxide of iron, which served as a cement to adhering pebbles, sand, and fragments of Unios and shells of other fresh-water mollusks. The remains of the megalonyx consisted of parts of two tibiæ of young individuals, an atlas, a fragment of a heel-bone, a metacarpal and a metatarsal bone, and a claw phalanx. With these were discovered a fragment of a cervical vertebra of a species of bison, various bones of the Virginia deer, a vertebra of a horse, probably _Equus complicatus_, a tooth of the tapir _Tapirus haysii_, and a part of the upper jaw of the wolf now known as _Ænocyon dirus_, but at that time called by Leidy _Canis primævus_.
The principal interest in these remains is to determine at what time during the Pleistocene the megalonyx lived. Some indications may be obtained from a study of its companions. From a part of a cervical vertebra Leidy could not name the bison, but it belonged probably to one of the extinct species. The deer is yet living, but appears to have existed through most of the Pleistocene. The species of horse represented is extinct, and there is no evidence that it lived after the Wisconsin glacial stage. Its latest representatives probably lived during the Sangamon stage. No tapir is known to have lived after the Wisconsin stage. The wolf, _Ænocyon dirus_, is believed to be represented in the numerous individuals found in the asphalt beds of Los Angeles, California, probably equivalent in age to the Aftonian.
