THE ILLINOIAN ICE INVASION 311 



The tapir (Tapirus haysii) is recorded by Cope 130 from near Richmond, 

 Wayne County, but the record has not been subsequently substantiated. 131 

 Bison antiquus 132 has been recorded from near Vincennes, Knox County. A 

 skull was found in a ditch at a depth of 6 feet. This is believed by Hay to 

 belong to pre- Wisconsin time and it may be referred to the Sangamon interval 

 with a considerable degree of certainty. 



In Bartholomew County mammal remains are reported as follows, possibly 

 from Sangamon deposits. 133 



Species Locality 



Mammut americanum. Sand bar in White River, one mile east of Walesboro. 



Elephas primigenins. In gravel pit one-half mile south of Walesboro, under 



7 feet of soil and gravel. 

 Alces americanus. In White River, one mile east of Walesboro. 



Odocoileus lirginianiis. Wa)Tie Township. 



In a limestone cave in Rock Cliff Quarry, just northwest of Williams, in 

 Lawrence County, the remains of several animals were found in a stalagmitic 

 deposit 20-30 feet below the level of the ground. Hay 133a remarks that the age 

 of the deposit cannot be determined but that the animals probably lived before 

 the oncoming of the Wisconsin ice. It seems quite proper to refer this material 

 to the Sangamon interval. Three species are represented, as noted below: 



Terrapane Carolina. Shell. 

 Tayassu lenis. Jaws and teeth. 

 Platygonus vetus. Molar. 



4. OHIO 



a. Old Soils 



The Sangamon interval has been identified from Ohio by Leverett and the 

 records of some of the old soils and forest beds published by Ohio geologists 

 should doubtless be referred to the same horizon. In Fairfield County 134 this 

 soil occurs at Clearport, between the surface soil and Illinoian drift, and- at 

 Lancaster, between the Wisconsin and Illinoian tills. From German Town- 

 ship, Montgomery County, Dachnowski 135 reports a Sangamon peat bed 

 beneath 80-100 feet of stratified clay and gravel (Wisconsin). This bed is ex- 

 posed in the channel of Twin Creek, a tributary of the Miami River. The 

 peat is from 1 to 4 feet in depth and the upper layers contain sphagnum mosses.
