316 LIFE OF THE PLEISTOCENE 



Ursus procerus. Overpeck Station, 168 on C. H. and D. Railway, four 



miles from Hamilton, Butler County, 23 feet 

 below the surface on "nest of petrified sticks." 



Ovibos moschatus. Youngstown, under 60 feet of gravel."' 



In Jackson and Muskingham counties several deposits occur from which 

 the remains of mammals have been reported. These are in stream deposits 

 evidently laid down by water from the Wisconsin ice. As the deposits con- 

 taining the bones are at the base of the sections, they may represent Sangamon 

 time. 



In Jackson County (Briggs, 157a ) at Salt Creek, in the northwestern part of 

 the county, the bones of an elephant, thot to be Elephas jacksoni ( = columbi) 

 were found. The section of the bank at this locality is as noted below : 



1. Yellowish clay 5J^ feet 



2. Yellowish sandy clay 7J^ " 



3. Ferruginous sand, partly cemented with iron 4-8 inches 



4. Chocolate colored sand or mud, the lower part containing remains of gram- 

 ineous plants 2 feet 



5. Sandy clay, light chocolate colored 1J^ " 



6. Sand and clay with large proportion of animal matter. Contains fossil 



bones 1-1K feet 



Height of section 17^-19 feet 



Many fossil bones are reported from salt wells in this county, including 

 the elephant and the Megatherium. 



In Muskingham County (Wyman 157a ) the valley drift of the Muskingham 

 River near Zanesville presents the section noted below: 



1. Yellow loam, stratified , 8 feet inches 



2. Fine sand 1 " 



3. Fine gravel " 6 



4. Yellow loam 2 " 



5. Pebbles of igneous rocks 6 " 



6. Yellow sand stratified „ " 6 



7. Yellow loam " 7 



8. Pebbles like number 5 with boulders 2 " 6 



9. Fine yellow sand, with remains of elephant 8 " 6 



Height of section 29 feet 7 inches 



m Miller, Proc. Biol. Soc. Wash., XIII, pp. 53-56. Hay (36th An. Rep., p. 775) believes 

 that the deposit may be older than the Illinoian as rock was found 3-4 feet below the bear skull. 

 As the old forest beds in this region are believed to be of Sangamon age it seems logical that 

 this ancient bear lived at the same time. 



16 ' Hay, 36th An. Rep., Geol. Surv. Ind., p. 641. If the depth of 60 feet is correct it 

 would probably penetrate the Wisconsin drift and the fossil musk ox may belong to the Sanga- 

 mon fauna.
