EOCENE. 



At least two liorizons are recognizal)le in the Eocene of the west coast, viz, 

 the Martinez and the Tejon; and there may also possibly be a third, which is 

 represented by the richly fo.ssiliferous beds exposed in the vicinity of Little Falls, 

 Lewis County, Wash. The last-mentioned horizon is probably above that of the 

 Tejon, although its relative position has not as yet been carefully worked out. 

 On account of the lack of definite information concerning the affiliations of its 

 fauna, the Little Falls beds will be included in the Tejon. The separation of the 

 Martinez and Tejon formations is based principally upon paleontologic evidence, 

 there being no apparent unconformity between them, although their iithologic 

 characters are usually somewhat different.
